Mojolin is self-funded How we score
Retool is our top pick for teams that build many internal apps on live production data: it connects to databases and APIs under existing permissions, ships auth, access controls and audit logging, and now accepts apps built by AI agents through its MCP server, CLI or React code import. Appsmith is the best value for developer teams, with an open-source edition, Git version control on every plan and a Business plan at $15 per user per month. ToolJet is the strongest pick if you want AI app generation, a built-in PostgreSQL database and self-hosting on Docker, Kubernetes or your own VPC. Teams whose internal tools are mostly scripts and jobs should look at Windmill, and ops teams without engineers should start with Softr or Glide.

Retool
Platform for building internal apps, workflows and agents on production data, with governance built in.
retool.com8.9
out of 10
Best for: Engineering teams that build many internal apps on live databases and need access control and audit logs.
Retool is the most complete platform here for teams that treat internal software as a product. Its app builder now starts from a prompt, but the bigger draw is what surrounds the app: every app connects directly to production data sources under existing permissions, and deployments include auth, access controls and audit logging. Teams that build with outside AI tools can use Retool's MCP server or CLI, or import React apps from Lovable, Replit and other platforms through a ZIP upload or GitHub sync. Workflows, a built-in database, mobile apps and external apps sit on the same platform.
The pricing model is the catch. Team and Business bill per builder and per internal user, so costs grow with every employee who opens an app. Team adds staging alongside production and 1,000 pooled AI credits, while Business adds external users, embedded apps, audit logs and unlimited environments. Git source control, SSO and SCIM are listed only on Enterprise, which also unlocks self-hosted and air-gapped deployment.
Standout feature
Apps built in other AI tools can be imported as React code and deployed inside Retool's governed environment.
Use cases
Support operations teams
Build a customer lookup and refund panel on the production database
Outcome: Agents act on live data inside existing permissions
Platform engineering teams
Move apps generated by coding agents into a governed environment
Outcome: AI-built tools ship with auth and audit logging
Finance and fintech teams
Run approval and reconciliation tools on a self-hosted Enterprise instance
Outcome: Sensitive data stays inside their own infrastructure
Key features
- App builder that turns a prompt into a production app
- MCP server and CLI for building apps with outside AI agents
- Import of React apps by ZIP upload or GitHub sync
- Direct connections to production data under existing permissions
- Workflows, a built-in database, mobile apps and external apps
Pros
- Free plan for up to 5 users with 250 pooled AI credits a month
- Auth, access controls and audit logging ship with deployed apps
- Enterprise runs on Retool Cloud, self-hosted or air-gapped
Cons
- Git source control and SSO are listed only on Enterprise
- Paid plans charge for every builder and every internal user
- Audit logs and external users start on the Business plan
Rank 2 · Runner-up
Appsmith
Open-source low-code platform for internal apps, with drag-and-drop widgets, JavaScript everywhere and Git version control.
appsmith.com8.8
out of 10
Best for: Developer teams that want an open-source, self-hostable builder with code-level control.
Appsmith is the best value for developer teams that want an open-source internal tool builder. Apps are assembled from drag-and-drop widgets, and every part of the logic, from data transforms to appearance, can be written in JavaScript, with external JS libraries available. Code lives in a centralized IDE with autocomplete, multi-line editing, debugging and linting instead of being scattered across widgets. Connectors cover databases, SaaS tools, LLMs and REST or GraphQL APIs, and self-hosting keeps internal data behind your firewall.
Git version control is unusual on a free tier: the Free plan includes it for 3 repos, Google SSO and public apps for up to 5 cloud users. Business, at $15 per user per month for up to 99 users, adds unlimited environments, repos and workspaces, workflows, reusable packages, audit logs and branding removal. The jump to Enterprise is steep at $2,500 a month for 100 users, which is where SAML or OIDC SSO, SCIM and CI/CD live.
Standout feature
Git version control is included even on the Free plan.
Use cases
Data teams
Build forms and dashboards on top of workflow scripts and SQL databases
Outcome: Colleagues run scripts safely through a UI
Self-hosting IT departments
Run the open-source edition next to internal databases
Outcome: Apps reach private data without exposing it
Software teams
Review internal app changes through Git branches
Outcome: Merged changes deploy automatically to the right environment
Key features
- Connectors for databases, SaaS tools, LLMs and REST or GraphQL APIs
- Drag-and-drop widgets plus custom widgets in JS, HTML and CSS
- Centralized IDE with autocomplete, debugging and linting
- Git version control with automatic deploys from environment branches
- Maintained open-source edition you can self-host
Pros
- Git version control included on the Free plan, with 3 repos
- Business plan at $15 per user per month covers up to 99 users
- Self-hosting gives secure access to data behind your firewall
Cons
- SAML or OIDC SSO and SCIM need Enterprise at $2,500 a month
- Free cloud use is capped at 5 users
- Building logic assumes comfort with JavaScript
Rank 3 · Also great
ToolJet
AI app builder for internal tools, with a built-in PostgreSQL database, workflows and agent builder.
tooljet.com8.5
out of 10
Best for: Teams that want AI-generated internal apps and the option to self-host on their own infrastructure.
ToolJet has moved from a low-code builder to an AI-first platform for internal tools while keeping its open-source roots. Its AI app builder generates functional apps, and the rest of the stack is in one place: 100+ integrations, ToolJet Database built on PostgreSQL, workflow automation, an agent builder and a ToolJet MCP server that lets outside coding agents build native, governed ToolJet apps. Self-hosting runs on Docker, Kubernetes, your VPC or on-premise, which suits teams with strict data rules.
The tiers need a close read. Free covers 2 builders, 50 end users and 10 apps with 100 AI credits. Basic at $23 per builder per month billed annually mostly adds AI credits, 2,000 per builder, and Pro adds custom styling and version control. The governance features most companies want, SSO, audit logs, Git sync, custom domains and unlimited apps, start on Team at $199 per builder per month, which makes ToolJet expensive for larger builder groups.
Standout feature
A built-in PostgreSQL-based database means small apps need no separate data store.
Use cases
Operations teams
Generate a back-office app from a description and store records in ToolJet Database
Outcome: A working tool without provisioning a separate database
Regulated companies
Self-host ToolJet on Kubernetes inside their VPC
Outcome: Internal apps run next to private systems

UI Bakery
Internal tool builder for admin panels, CRUD apps and dashboards on live databases, with an AI development agent.
uibakery.io8.4
out of 10
Best for: Small developer teams that want a low per-developer price and the option to export React code.
UI Bakery covers the core internal tool jobs, admin panels, CRUD apps, dashboards and approval workflows, on top of live databases and services, at prices that suit small teams. Its AI Development Agent builds and deploys an app from a chat conversation, which UI Bakery says takes 2 minutes on average. Apps connect to 45+ databases and APIs, a running MCP server can be added as a data source, and a hosted database helps with quick prototypes. React code export is a useful safeguard against lock-in.
The Free plan includes unlimited apps and data source connections, unlimited public app users and release history. Builder costs $20 per developer per month billed annually, or $25 monthly, and adds environments, app export, built-in roles and up to 50 workspace view seats. Team at $35 per developer per month billed annually adds role-based access control, audit logs and premium support. A self-hosted edition and SSO options cover stricter deployments.
Standout feature
React code export means an app can leave the platform if needs change.
Use cases
Operations teams
Build an inventory tool that tracks stock and triggers reorders
Outcome: Stock levels are managed from one internal app
Finance teams
Review, filter and approve vendor invoices
Outcome: Approvals happen in a single queue
Startups
Prototype an admin panel on the hosted database before connecting production
Outcome: A working tool before the data model settles
Key features
- AI Development Agent that builds and deploys apps from chat
- 45+ databases and APIs as data sources
- MCP servers as data sources for app interfaces
- Hosted database for prototypes
- React code export and self-hosted deployment
Pros
- Free plan with unlimited apps and data source connections
- Builder plan from $20 per developer per month

Rank 5
Softr
No-code builder for apps, databases, workflows and portals, aimed at business teams.
softr.io8.3
out of 10
Best for: Ops teams without engineers that need internal tools and client portals on a small budget.
Softr is the easiest way in this list for an operations team to ship an internal tool without engineers. Every plan includes unlimited apps, databases, workflows, agents and forms, and Softr's own databases mean a team can start without connecting an external data source. Workflows run actions inside monthly allowances, starting at 500 on Free, and the Softr API and MCP let other tools work with your apps. Softr also counts team users, who share a business email domain with a builder, separately from client users, which helps when one workspace serves staff and customers.
Free covers up to 3 builders, 5 app users, 5,000 records and 5 AI credits a month. Basic at $19 per month adds a custom domain, conditional form logic and automated database backups, with one builder included. Pro at $99 per month removes Softr branding and adds more sign-in options, and Business at $329 per month adds filtered user sync and two-factor authentication. Teams that need custom code or complex queries should look at a developer platform instead.
Standout feature
Unlimited apps, databases, workflows and forms are included even on the Free plan.
Use cases
Small operations teams
Replace a shared spreadsheet with a request tracker on Softr Databases
Outcome: Requests get owners and statuses
Agencies
Give clients a login to see project status

- Softr Workflows with monthly action allowances
- Softr API and MCP access
- Separate counting of team users and client users
Pros
- Cheapest paid plan in this list at $19 per month
- Free plan with up to 3 builders
- Builders can be added as app users at no extra cost
Cons
- Free plan allows only 5 app users and 5,000 records
- Removing Softr branding needs Pro at $99 per month
- Less suited to custom code than developer platforms
Rank 6
Windmill
Open-source, code-first platform for scripts, workflows, apps and AI agents, with a self-hostable job engine.
windmill.dev8.3
out of 10
Best for: Engineering teams whose internal tools are mostly scripts, jobs and data pipelines that need a UI.
Windmill approaches internal tools from the engineering side. A function in any of 20+ languages becomes an API endpoint and a form, with imports resolved and versions locked at each deploy. Flows are drawn as DAGs or written in Python or TypeScript, scripts and flows get webhooks and schedules automatically, and the app editor mixes drag-and-drop with code for custom interfaces. The same platform runs data pipelines and AI agents on a job engine you can self-host on Fargate, Docker or Kubernetes.
The open-source edition is generous: unlimited executions, 3 workspaces, up to 50 users with SSO capped at 10, and 100 free app guests per 30 days who sign in through your identity provider without taking a seat. Enterprise starts from $120 a month and adds audit logs, SAML with group sync, a commercial licence and 24/7 support with a 3 hour response time. Seats cost $20 per builder and $10 per non-builder per month, plus compute units for workers, so model your setup with the vendor's calculator.
Standout feature
Any script becomes an API endpoint and a form automatically.
Use cases
Finance engineering teams
Turn a reconciliation script into a form colleagues can run
Outcome: Repeatable jobs without a custom frontend
Data teams
Schedule pipelines and expose results through an app
Outcome: Pipelines and their UI live in one platform
Platform teams
Self-host the job engine on Kubernetes for internal automation
Outcome: Unlimited executions on their own infrastructure
Key features
- Scripts in 20+ languages, including TypeScript, Python, Go, Rust, Bash and SQL
- Flows drawn as DAGs or written as code
- Auto-generated UIs and webhooks for every script and flow
- Low-code app editor that mixes drag-and-drop and code
- Schedules plus Postgres, WebSocket and email triggers
Pros
- Free open-source edition with unlimited executions
- Git-based collaboration fits engineering workflows
- 100 free app guests per 30 days, even on the free edition
Cons
- Assumes engineers who write code
- Free edition caps SSO at 10 users and groups at 4
- Enterprise pricing combines seats and compute units, so it takes modeling
Rank 7
Glide
AI app builder that turns spreadsheets into business apps and agents for desktop and phone.
glideapps.com8.2
out of 10
Best for: Ops and field teams that run on Excel or Google Sheets and want apps without code.
Glide is built for teams whose operations already live in spreadsheets. You drop in an Excel file or Google Sheet, its SheetSense feature reads the sheets, formulas, lookups and notes, and the agent builds a working app for desktop and phone. Any number in the app can be inspected to see how it was calculated, data entered in the field updates the back office immediately, and role-based views keep employees, managers, customers and partners to their own information. Teams that prefer their own AI tools can build over MCP from Claude, Gemini or ChatGPT into the same apps.
Pricing is credit-based and billed monthly. Free covers 2 team members and 10 projects, Basic at $25 per month includes 100 credits, 2 published apps and 1 workflow, and Plus at $50 per month adds public apps and 5 published apps. Most teams will land on Pro, from $125 per month with 5 members, unlimited published apps, premium integrations and org-level roles. It is a weaker fit for engineers who want SQL queries on production databases.
Standout feature
SheetSense reads existing formulas and lookups, so the app reflects how the spreadsheet already works.
Use cases
Field service teams
Log site inspections and flag failures from a phone
Outcome: The back office sees results immediately
Operations managers
Turn an inventory spreadsheet into a stock tracking app
Outcome: Stock across sites in one place
Crew-based businesses
Assign crews to sites and shifts
Outcome: A shared weekly schedule everyone can open
Key features
- Agent that reads a spreadsheet and builds a working app
- Apps for desktop and phone that sync with the back office
- MCP connection for Claude, Gemini, ChatGPT and other agents
- Role-based views for employees, managers, customers and partners
- Ready-made templates for inspections, inventory and crew scheduling
Pros
- Fastest route from an existing spreadsheet to an app
- Apps stay private to your company by default
- Free plan for 2 team members and 10 projects
Cons
- Basic allows only 2 published apps and 1 workflow
- Unlimited published apps need Pro from $125 per month
- Single sign-on is listed only on Enterprise
Rank 8
Budibase
Open-source platform for business process apps, agents and automations, self-hosted or in Budibase Cloud.
budibase.com8.1
out of 10
Best for: IT teams that want unlimited users on a self-hosted, open-source platform for requests and approvals.
Budibase has refocused on business processes: apps give people an interface to request, review and complete work, agents handle requests using your data, tools and approval rules, and automations run event-driven workflows. A service portal brings apps, requests and approvals into one place, and the platform adds data tables, connections to existing systems and an API explorer for testing API actions. Budibase cites one Bulgarian Government app that supports 100k+ users.
The self-hosted Community edition is the main reason to choose it: it is free with unlimited users, apps, agents, automations and requests, plus standard SSO. Budibase Cloud starts at $299 per month with 2 creators, 20 end users, 250K monthly actions and 50K monthly AI credits, and extra creators cost $50 each per month with annual billing. Actions are hard limits rather than overage charges, which keeps bills predictable but means work stops when you reach the cap until you raise the allowance.
Standout feature
The self-hosted Community edition has no user limit.
Use cases
IT departments
Route equipment purchase requests through approvals
Outcome: Requests, approvals and records in one portal
Public sector teams
Self-host a citizen-facing or staff process app

- Self-hosting, including air-gapped deployment on Enterprise
Pros
- Self-hosted Community edition is free with unlimited users and apps
- Hard monthly action limits keep cloud costs predictable
- 28K GitHub stars and an active open-source project
Cons
- Budibase Cloud starts at $299 per month
- Cloud base plan includes only 2 creators and 20 end users
- Extra creators cost $50 each per month on annual billing
Rank 9
DronaHQ
Low-code platform for internal apps and AI agents, with SSO, RBAC, secrets and audit trail built in.
dronahq.com8.0
out of 10
Best for: Companies that want unlimited app users on a flat monthly plan, in the vendor's cloud or their own.
DronaHQ positions itself as the layer that turns AI-built code into a production internal app. You build with prompts, the visual builder for web and mobile, or Claude Code and Cursor through DronaHQ MCP, and the platform supplies what generated code usually lacks: SSO, RBAC, an encrypted secrets vault, environments, an audit trail and hosting in DronaHQ's cloud or yours. Its agent builder covers sub-agents, RAG on your documents, guardrails and tracing, with agents running in chat, voice, WhatsApp, email or behind an API.
Pricing is by tasks rather than seats, so every plan has unlimited users. Starter costs $100 per month billed annually, or $140 monthly, with unlimited apps and connectors, 100+ UI components and version history. Business at $500 per month billed annually adds data environments, white labelling and SAML or OpenID Connect SSO, while audit logs and granular permissions are listed on Enterprise. There is no free plan, only a one month trial of Business.
Standout feature
Every plan includes unlimited users, with usage billed by tasks.

Superblocks
Platform for building and governing AI-generated internal apps and agents, with its Clark AI agent and VPC deployment.
superblocks.com7.8
out of 10
Best for: IT and security teams that want governed AI app building, with enterprise deployment in their own cloud.
Superblocks has turned its internal app builder into a governance platform for AI-generated software. Builders can work with its Clark AI agent or bring Claude Code, Codex, Cursor or another coding agent, while IT controls integrations, identity, infrastructure policy and code security. Its integration gateway centralizes access to MCPs, APIs and databases with audit trails and rate limits, and Enterprise runs Superblocks inside your VPC on AWS, GCP or Azure.
The Teams plan, at $100 per month billed annually or $125 monthly with a 14-day trial, is a small entry point: it includes 100 Governed Agent Units a month, the Clark agent, staging and production environments, 50+ integrations, unlimited end users and up to 15 builders, but only 1 hosted app, with more at $10 per app per month. Source control through GitHub, GitLab, Bitbucket or Azure DevOps, SSO, RBAC, audit logs and VPC deployment are all Enterprise features, so most buyers will need a custom quote.
Standout feature
Builders can use their own coding agent while IT sets one governed path to production.
