Mojolin is self-funded How we score

Hightouch is our top pick: it syncs to 300+ destinations, reads changes through your warehouse's own CDC for low-latency syncs, and offers a free tier with 2 active syncs, though paid plans are quoted by sales. Fivetran Activations, the former Census, is the natural choice for Fivetran customers, with 200+ activation destinations and 3,500 free monthly active rows. RudderStack and Segment bundle reverse ETL into a wider customer data platform with free tiers and paid plans from $265 and $120 a month. Polytomic is the strongest all-in-one sync tool with a self-hosted option, and Airbyte, Weld and Omnata are the budget routes when you already use their ELT or Snowflake.

    Hightouch

    Reverse ETL and composable CDP that syncs warehouse tables and SQL models to 300+ business tools.

    hightouch.com

    8.8

    out of 10

    Best for: Data teams that run many warehouse-to-app syncs and want low-latency pipelines, Git workflows and strong governance.

    Hightouch began as a reverse ETL tool and that product is still its core: you pick a table or write SQL in Snowflake, Databricks, BigQuery or Redshift, map fields, and sync to more than 300 destinations on a schedule or in real time. Real-time syncs read the warehouse's native change data capture, and batch jobs use warehouse compute for large backfills.

    The tooling for data teams is the deepest in this list. Pipelines can live as YAML in a Git repo, dbt models can be imported and syncs triggered when dbt jobs finish, and a row-level debugger shows every API call. Approval flows, sync templates and staging workspaces help larger teams keep control, and Hightouch says it never stores customer data. The Basic tier is free with 2 active syncs, unlimited destinations and seats. Everything beyond that is usage-based and quoted by sales, so budget planning starts with a demo.

    Standout feature

    Real-time syncs built on the warehouse's own change data capture, with Git version control for every pipeline.

    Use cases

    • Analytics engineers

      Sync dbt-built lead scores from Snowflake to Salesforce after each dbt run

      Outcome: Sales reps see updated scores without CSV imports

    • Growth marketers

      Push warehouse audiences to Google Ads and Meta

      Outcome: Ad targeting and suppression lists that follow the warehouse

    • Support operations

      Send account health and plan data into Zendesk

      Outcome: Agents prioritize tickets with current customer context

    Key features

    • Syncs to 300+ destinations in real time or on a schedule
    • Real-time syncs that read the warehouse's native change data capture
    • Git version control with YAML files and a dbt integration that triggers syncs after dbt jobs
    • Row-level debugger, sync logs written back to the warehouse and custom alerts
    • Approval flows, sync templates, staging workspaces and role-based access control

    Pros

    • Free tier with unlimited destinations and user seats
    • Never stores customer data and runs syncs on ephemeral workers in AWS, GCP or Azure
    • Grows into a full composable CDP with audiences, identity resolution and event collection

    Cons

    • No published prices for paid plans
    • Free tier is limited to 2 active syncs
    • Product line is wide, so teams that only need reverse ETL may pay for more platform than they use
  2. Rank 2 · Runner-up

    Fivetran Activations (Census)

    Reverse ETL and audience building from Fivetran, built on its acquisition of Census.

    fivetran.com

    8.6

    out of 10

    Best for: Teams that already replicate data with Fivetran and want ingestion and activation on one usage-based plan.

    Fivetran bought Census and now sells its reverse ETL as Fivetran Activations, so ingestion and activation share one account, one contract and one usage model. The product syncs modeled warehouse data to 200+ pre-built destinations such as Salesforce, HubSpot and marketing platforms, with observability across the whole pipeline.

    Beyond plain syncs, Audience Hub lets marketers build audiences in the warehouse without SQL, and AI Columns generate new fields with models from OpenAI, Anthropic and Google. Pricing follows monthly active rows. The Free plan includes 3,500 activation MAR, each new activation gets a 14-day trial, and Fivetran's own Standard plan examples put a Snowflake to Salesforce activation at $202.25 a month and Snowflake to HubSpot at $197.96 for companies with up to 200 employees. Audience Hub sits on the Enterprise plan, and annual contracts save up to 22%. Teams that do not use Fivetran for ingestion will find fewer reasons to choose it over a standalone tool.

    Standout feature

    Ingestion, transformation and activation on one Fivetran plan, with published per-activation price examples.

    Use cases

    • Fivetran customers

      Add reverse ETL to HubSpot without a second vendor

      Outcome: One contract and dashboard for ingestion and activation

    • Marketing teams

      Build warehouse audiences in Audience Hub

      Outcome: Self-service segments without SQL requests to the data team

    • RevOps teams

      Enrich CRM accounts with AI Columns before syncing

      Outcome: New fields generated in the warehouse and delivered to Salesforce

    Key features

    • 200+ pre-built reverse ETL destinations
    • Audience Hub for building audiences in the warehouse without SQL
    • AI Columns that generate new fields with OpenAI, Anthropic or Google models
    • Datasets for modeling and transforming data into views for activation
    • One plan and contract across connections, transformations and activations

    Pros

    • Free plan covers 3,500 activation MAR alongside 500,000 connection MAR
    • Each new activation comes with a 14-day free trial
    • Fivetran publishes median monthly list prices for common activations

    Cons

    • Audience Hub needs the Enterprise plan
    • Usage pricing per activation makes totals harder to predict
    • Best fit is inside the Fivetran ecosystem rather than as a standalone tool

    RudderStack

    Warehouse-native customer data platform with event streaming and reverse ETL in its Core product.

    rudderstack.com

    8.5

    out of 10

    Best for: Engineering-led teams that want event collection and warehouse-to-app syncs from one vendor with a free tier.

    RudderStack Core combines event collection, warehouse destinations and reverse ETL, which suits teams that would otherwise buy a CDP and a separate activation tool. Its reverse ETL turns warehouse tables into identify and track calls, runs custom SQL models, and supports upsert or mirror modes with a visual mapper. Syncs run on intervals or CRON expressions, and Airflow or Dagster can trigger them.

    Data can be changed in flight with JavaScript or Python transformations, and the data quality toolkit checks types for each destination before data reaches more than 200 tools. The Free plan includes Reverse ETL with 250K events a month and 10 connections, and Growth starts at $265 a month for 1 million events with 25 reverse ETL connections. Each record a reverse ETL sync sends counts as an event, so heavy syncs raise the bill. Rudder Lookout, a separate marketer-facing audience product in public beta, starts at $12,000 a year.

    Standout feature

    Reverse ETL included in a CDP Free plan, with in-flight JavaScript and Python transformations.

    Use cases

    • Product engineering teams

      Collect app events and sync warehouse traits back to Braze

      Outcome: One pipeline vendor for inbound and outbound customer data

    • Data engineers

      Trigger reverse ETL from Airflow after nightly models finish

      Outcome: Syncs run in the same orchestration as the rest of the stack

    • Startups

      Start syncing a few models on the Free plan

      Outcome: Working CRM enrichment at no cost under 250K events

    Key features

    • Table sync and SQL models that run on the warehouse and sync results
    • Upsert and mirror sync modes
    • Visual data mapper and custom CRON sync schedules
    • Apache Airflow and Dagster orchestration integrations
    • JavaScript or Python transformations on data in flight to 200+ tools

    Pros

    • Reverse ETL is included on the Free plan
    • Same platform handles SDK event collection and warehouse destinations
    • Rudder Lookout adds marketer-facing audience building when needed

    Cons

    • Core is priced on events, so record volume from syncs counts toward the bill
    • Free plan caps Reverse ETL connections at 10
    • Lookout audience plans start at $12,000 a year
  4. Rank 4

    Twilio Segment

    Customer data platform whose Connections product includes Reverse ETL from major warehouses.

    segment.com

    8.4

    out of 10

    Best for: Teams already collecting events in Segment that want warehouse models sent to the same destinations.

    Segment added Reverse ETL to its Connections product, so warehouse tables and SQL models can flow to the same destinations that already receive tracked events. Documented sources include Snowflake, BigQuery, Databricks, Redshift, Postgres, Azure and Db2, and mappings use Segment's Destination Actions framework.

    The pricing is easy to start with. The Free plan includes 500,000 Reverse ETL records a month with 2 sources and 1 warehouse destination, and Team starts at $120 a month with 1,000,000 Reverse ETL records, unlimited sources, public API access and a 14-day trial. Segment says more than 25,000 companies use its platform. The limits show at scale: the plan table lists 1 sync a day on Free and 2 on Team, with custom schedules on the Business plan, and features such as data governance and advanced permissions also sit on Business. For teams already on Segment, it is the shortest path to warehouse activation.

    Standout feature

    500,000 Reverse ETL records a month on a free plan, the largest free record allowance in this list.

    Use cases

    • Existing Segment customers

      Send warehouse churn scores to the destinations already wired to Segment

      Outcome: No second activation vendor to manage

    • Lifecycle marketers

      Sync subscription status from BigQuery to an email platform

      Outcome: Campaigns based on billing data that lives in the warehouse

    • Small product teams

      Test reverse ETL on the Free plan

      Outcome: Up to 500,000 synced records a month at no cost

    Key features

    • Reverse ETL from Snowflake, BigQuery, Databricks, Redshift, Postgres, Azure and Db2
    • Same destination catalog as Segment event streams, with 550+ pre-built destinations
    • Destination Actions for mapping warehouse fields to destination calls
    • Functions for custom code, with 50 hours on Free and Team
    • Public API access on Team

    Pros

    • Free plan includes 500,000 Reverse ETL records a month
    • Low entry price for the Team plan
    • Easy to add if Segment already handles event tracking

    Cons

    • Free and Team limit warehouse syncs to 1 and 2 a day
    • Team includes 1,000,000 Reverse ETL records before custom volume
    • Governance features such as advanced roles need the Business plan

    Polytomic

    One sync platform for ETL, CDC streaming, reverse ETL and two-way app syncs, with a self-hosted option.

    polytomic.com

    8.3

    out of 10

    Best for: Teams that want one tool for data in both directions and need self-hosting or HIPAA compliance.

    Polytomic treats reverse ETL as one direction of a general sync engine. The same platform runs ETL into warehouses, CDC streaming, reverse ETL out to apps, and syncs between databases, spreadsheets and HTTP APIs, so a RevOps team can push warehouse fields into Salesforce while pulling HubSpot data the other way.

    Syncs can be built with point-and-click filters or SQL, and Polytomic only sends changed records to save API limits and warehouse compute. Integrations include Snowflake, BigQuery, Databricks, Salesforce, HubSpot, Marketo, NetSuite, Stripe and Google, Facebook and LinkedIn Ads. Enterprise buyers get a self-hosted deployment, Terraform support, audit logs and SOC 2, GDPR, CCPA and HIPAA compliance. Pricing begins at $500 a month with a 14-day trial, and the Standard tier adds multiple sync destinations and live chat support, while Enterprise adds on-prem deployment, SSO and a dedicated engineer. There is no free plan.

    Standout feature

    ETL, CDC and reverse ETL in one product with a self-hosted deployment option.

    Use cases

    • RevOps teams

      Sync product usage from Snowflake into Salesforce and HubSpot

      Outcome: Both CRMs show the same account data

    • Healthcare data teams

      Run reverse ETL inside their own cloud

      Outcome: HIPAA workloads without data leaving their environment

    • Lean data teams

      Replace separate ELT and reverse ETL vendors

      Outcome: One contract and one UI for syncs in both directions

    Key features

    • ETL, ELT, CDC streaming, reverse ETL and general data syncs in one platform
    • Two-way integrations with Salesforce, HubSpot, Marketo, NetSuite, ad platforms and more
    • Point-and-click filtering plus SQL query support
    • Syncs only changed data to save API limits and compute
    • Self-hosted deployment, Terraform support and fine-grained RBAC

    Pros

    • Replaces separate ELT and reverse ETL tools
    • Self-hosted option for teams that must keep data in their own cloud
    • SOC 2, GDPR, CCPA and HIPAA compliant

    Cons

    • $500 a month entry price is high for small teams
    • No free plan
    • Multiple sync destinations and SSO need higher tiers
  6. Rank 6

    Airbyte

    Open-source data movement platform that added data activation syncs from the warehouse to apps.

    airbyte.com

    8.2

    out of 10

    Best for: Teams already using Airbyte for ingestion that want low-cost syncs back into HubSpot, Zendesk or marketing tools.

    Airbyte is best known for moving data into warehouses, and it now runs the opposite direction too under the name data activation. Its docs describe syncs from Snowflake, BigQuery or Redshift into tools such as HubSpot, Customer.io, Marketo and Zendesk, with declarative mappings that define how warehouse columns land in destination fields and a separate rejected records feature.

    The main reason to choose Airbyte is cost and consolidation. Data activation is listed on every edition, including self-hosted Core, and Cloud Standard starts at $20 a month with 5 credits and a 14-day trial with 400 credits. Plus starts at $189 a month and adds 15-minute syncs and SSO. The tradeoff is depth: the activation destination catalog is small next to Hightouch or Fivetran Activations, and there is no audience builder for marketers. Teams already running Airbyte pipelines can add a few CRM or support syncs without a new vendor.

    Standout feature

    Data activation included even on free self-hosted Core, with Cloud from $20 a month.

    Use cases

    • Marketing operations

      Sync engagement scores from Snowflake into HubSpot contact properties

      Outcome: Targeted campaigns based on product usage

    • Support teams

      Deliver customer health scores to Zendesk

      Outcome: Tickets prioritized by account health

    • Self-hosting engineers

      Run ingestion and activation on Airbyte Core

      Outcome: Both directions with no license fee

    Key features

    • Data activation (reverse ETL) on Core, Standard, Plus, Pro and Enterprise Flex
    • Warehouse-to-app syncs from Snowflake, BigQuery and Redshift to tools such as HubSpot, Customer.io, Marketo and Zendesk
    • Declarative field mapping between warehouse and destination
    • Rejected records handling documented as part of the sync flow
    • 700+ connectors for ingestion on the same platform

    Pros

    • Lowest monthly plan price in this list at $20 a month
    • Self-hosted Core includes data activation at no license cost
    • One tool for ingestion and activation

    Cons

    • Activation destination list is much shorter than dedicated tools
    • Standard syncs at most hourly; 15-minute syncs need Plus
    • No marketer-facing audience builder
  7. Rank 7

    Omnata

    Snowflake native app that syncs data in and out of Snowflake with no middleware.

    omnata.com

    8.1

    out of 10

    Best for: Snowflake-only teams that want flat daily pricing and to pay with Snowflake credits.

    Omnata takes a different approach from the other tools here: instead of a SaaS service that reads your warehouse, it installs as Snowflake Native Apps, so syncs run inside your own Snowflake account. The Sync Engine is a free listing, and you add a plugin for each app, such as Salesforce CRM, HubSpot, Salesforce Marketing Cloud or Marketo.

    Pricing is a flat fee per plugin per day, charged only on days when syncs are active, with no extra charges for data, objects or refreshes. Salesforce CRM and HubSpot cost $6.50 a day for the first sync direction and $3.00 for the second, Salesforce Marketing Cloud is $10.00 a day, the cheapest bi-directional plugin starts at $5.00, and Google Sheets is free. In the US and some other regions you can pay with Snowflake capacity credits through the Marketplace. The limits are clear: Omnata only serves Snowflake, and its plugin list is shorter than dedicated reverse ETL catalogs.

    Standout feature

    Runs inside Snowflake as a native app with flat per-day plugin pricing and no volume charges.

    Use cases

    • Snowflake data teams

      Keep Salesforce accounts in sync with Snowflake models

      Outcome: Two-way CRM sync billed at a flat daily rate

    • Security-focused companies

      Run reverse ETL without a third-party data processor

      Outcome: Data stays within the Snowflake account

    • Finance and procurement

      Pay for syncs with committed Snowflake credits

      Outcome: No new vendor contract to approve

    Key features

    • Runs as Snowflake Native Apps inside your Snowflake account
    • Bi-directional plugins for Salesforce CRM, HubSpot, Salesforce Marketing Cloud, Marketo and more
    • Flat fee per plugin per day, charged only when syncs are active
    • No extra charges for data volume, objects or refreshes
    • Pay through the Snowflake Marketplace with capacity credits in the US and some other regions

    Pros

    • Predictable daily pricing with no row or record meters
    • Data does not pass through a third-party middleware service
    • Free two-way Google Sheets plugin

    Cons

    • Only works with Snowflake
    • Each sync direction and extra connection adds a daily fee
    • Smaller plugin catalog than dedicated reverse ETL vendors
  8. Rank 8

    Weld

    Data platform that combines ELT from 300+ sources, SQL transformations and reverse ETL.

    weld.app

    8.0

    out of 10

    Best for: Small data teams that want ingestion, modeling and reverse ETL in one tool at a fixed monthly price.

    Weld bundles three jobs that smaller data teams often buy separately: replicating data from 300+ sources into a warehouse, modeling it with SQL, GitHub or dbt, and syncing the results back to business tools with reverse ETL. An AI agent called Ed writes and checks SQL, and a REST API and MCP server let agents and scripts manage pipelines.

    Plans are tiered by monthly active rows and connectors. Basic is $99 a month billed yearly with 5M MAR, 2 connectors, 1 user and daily syncs. Premium at $389 a month billed yearly adds 6 connectors, 3 users and hourly syncs, and Business at $959 adds 10 connectors and 15-minute syncs. Extra users cost $19 a month and paying yearly saves 20%. Every plan starts with a 14-day trial, but there is no free plan afterward. Reverse ETL destinations are listed on every plan, though the catalog is smaller than at a dedicated activation vendor.

    Standout feature

    ELT, AI-assisted SQL modeling and reverse ETL on one plan from $99 a month billed yearly.

    Use cases

    • Small ecommerce data teams

      Load Shopify and ad data, model it and sync segments back

      Outcome: One tool covers the whole loop

    • Analysts without engineers

      Use Ed to write SQL for a CRM sync

      Outcome: Models ready to activate without hand-written queries

    • Agencies

      Run pipelines through the Weld Connect API

      Outcome: Repeatable setups across client accounts

    Key features

    • Reverse ETL to business tools alongside ELT from 300+ sources
    • SQL editor, GitHub and dbt for transformations
    • Ed, an AI agent that writes and checks SQL
    • Log-based CDC replication, an add-on on Business and included on Enterprise
    • Weld Connect REST API and MCP server for agent workflows

    Pros

    • Ingestion, modeling and reverse ETL on one subscription
    • Plans are tiered by monthly active rows with published add-on prices
    • 14-day free trial on every plan with no credit card

    Cons

    • Basic includes 2 connectors, 1 user and daily syncs
    • Hourly syncs need Premium and 15-minute syncs need Business
    • No free plan after the trial
  9. Rank 9

    Rivery

    Boomi-owned data pipeline platform with ingestion, orchestration and reverse ETL in one workflow.

    rivery.io

    7.6

    out of 10

    Best for: Data teams that want reverse ETL as a step in larger orchestrated pipelines, including pushes to any REST API.

    Rivery, now part of Boomi, treats reverse ETL as one step in a larger data workflow. You define a target app such as Salesforce, Tableau or any REST API, write the expected POST request body with variables, query Snowflake or Databricks for the data, and map query results to those variables. Kits for HubSpot, Tableau and Slack give a head start.

    That design is flexible, since any API can become a destination, but it asks for more setup than the field mappers in Hightouch or Segment. The rest of the platform covers ingestion from 200+ sources, SQL and Python transformations, orchestration with branching and sub-rivers, and built-in versioning. Pricing is pay as you go at $0.9 per BDU credit on Base, which allows 2 users and syncs every 60 minutes, while Professional adds unlimited users, Python and 15-minute syncs. The free trial runs 14 days or 1,000 credits worth $1,200, whichever ends first.

    Standout feature

    Any REST API can be a reverse ETL target, inside the same orchestrated workflow as ingestion.

    Use cases

    • BI teams

      Refresh Tableau dashboards after a pipeline finishes

      Outcome: Reports update as soon as new data lands

    • Finance data teams

      Push Snowflake results into NetSuite

      Outcome: Operational systems receive modeled numbers automatically

    • Support operations

      Send alerts to Slack from warehouse queries

      Outcome: Faster responses to tickets and internal requests

    Key features

    • Reverse ETL in the same workflow as ingestion and transformation
    • Push to Salesforce, HubSpot, Tableau, Slack or any REST API
    • Pre-built kits for common reverse ETL workflows
    • SQL and Python transformations with workflow orchestration
    • 200+ data sources and built-in version control

    Pros

    • Reverse ETL included on every edition
    • Any REST API can be a target through a POST request template
    • Free trial includes 1,000 credits worth $1,200

    Cons

    • Syncs are built as API request templates, which takes more setup than a field mapper
    • Base edition syncs at most every 60 minutes
    • Credit pricing needs the estimator to forecast

Buying guide

How to choose

Start from the destinations you must reach

List every CRM, ad network, marketing platform and support desk you plan to feed, then check each vendor's destination catalog and whether the connector supports the objects you need, such as custom Salesforce objects or Google Ads customer match lists. Hightouch lists 300+ destinations, Fivetran Activations and RudderStack 200+, and Segment 550+ across its whole platform. ELT tools such as Airbyte, Weld and Rivery cover the common CRMs but have shorter outbound lists, and Rivery can post to any REST API.

Check how changes are detected and how often syncs run

Most reverse ETL tools compare query results between runs and send only changed rows, which saves destination API limits. Hightouch can also listen to the warehouse's native change data capture for near real-time syncs. Plan limits matter: Airbyte Standard syncs at most hourly, Segment Free and Team run 1 and 2 syncs a day, Weld Basic syncs daily, and Rivery Base runs every 60 minutes.

Model the bill on synced records, not seats

Pricing units differ widely: monthly active rows at Fivetran and Weld, Reverse ETL records at Segment, events at RudderStack, credits at Airbyte and Rivery, a flat fee per plugin per day at Omnata, and usage contracts at Hightouch. Estimate how many rows change each day in the models you sync, multiply by the destinations, and check where each vendor's next tier starts.

Decide who will build the syncs

If marketers need to build audiences without SQL, look at Hightouch Customer Studio, Fivetran Activations' Audience Hub or Rudder Lookout. If only the data team will configure syncs, a SQL model plus a field mapper is enough, and Git version control or dbt integration matters more. Hightouch and Polytomic both offer configuration as code.

Review security and where data is processed

Reverse ETL tools read your warehouse and write to customer-facing systems, so check SOC 2 reports, SSO, role-based access and private networking. Hightouch says it never stores customer data, Polytomic and Airbyte can run in your own cloud, and Omnata runs inside your Snowflake account with no middleware.

Frequently asked questions

+What is the best reverse ETL tool in 2026?

Hightouch is our top pick for data teams, with 300+ destinations, CDC-based real-time syncs and a free tier with 2 active syncs. Fivetran Activations, the former Census, is the best alternative for Fivetran customers, with 200+ destinations and 3,500 free monthly active rows.

+What is reverse ETL?

Reverse ETL copies modeled data from a warehouse such as Snowflake or BigQuery back into operational tools like Salesforce, HubSpot, ad platforms and Zendesk. It lets sales, marketing and support teams act on warehouse data inside the apps they already use, instead of reading it in dashboards.

+Is there a free reverse ETL tool?

Yes. Segment's Free plan includes 500,000 Reverse ETL records a month, RudderStack Free includes Reverse ETL with 250K events, Hightouch Basic allows 2 active syncs and Fivetran's Free plan covers 3,500 activation rows. Airbyte Core includes data activation and is free to self-host.

+What happened to Census?

Fivetran acquired Census and now sells its reverse ETL as Fivetran Activations. The getcensus.com pricing page now points to Fivetran's pricing, where activations are billed by monthly active rows alongside connections and transformations.

+How is reverse ETL priced?

Units differ by vendor: monthly active rows at Fivetran and Weld, Reverse ETL records at Segment, events at RudderStack, credits at Airbyte and Rivery, and a flat fee per plugin per day at Omnata. Hightouch and Polytomic quote paid plans, with Polytomic starting at $500 a month.

+Do I need a CDP or a reverse ETL tool?

If your customer data is already modeled in a warehouse, a reverse ETL tool sends it to apps without a separate copy. If you also need to collect web and app events, RudderStack and Segment include reverse ETL in their CDPs, and Hightouch sells event collection and audiences as separate products.
