Retool

This Retool review covers what Retool is used for, the key features of this low code platform, Retool pricing, self-hosting, where it shines and falls short, and how it compares with other internal tool builders. Retool gives technical teams a drag and drop editor with pre-built components such as tables, forms, charts and buttons, and lets them connect those components to multiple data sources with SQL, JavaScript and API queries. You build apps with custom logic in JavaScript where the no code parts stop, and deploy apps to your team in just a few clicks, so a working app on live production data takes hours instead of weeks. Retool also covers the jobs around those apps: Retool Workflows for scheduled and triggered automation, Retool Database for data storage, Retool Mobile for native iOS and Android apps, and AI agents that run tasks on your data.

What is Retool used for?

Retool lets teams create internal tools and other internal business tools that would otherwise take an engineering team weeks of front-end work, and automate processes around them. Typical Retool apps are admin dashboards, customer support tools that pull an order, a refund and a user profile into one screen, back-office consoles for operations, approval flows, inventory and logistics tools, and data-entry apps that write straight to a production database. Because Retool connects to existing databases and APIs rather than replacing them, it is a thin, fast layer on top of the systems a company already runs.

The typical builder is a developer or a technical operations person who knows some SQL and JavaScript. Retool is not a no code tool for non technical users: you write queries, transform data with JavaScript and wire components to that data. For engineering teams, that is the point. They get full control over the logic without building UI plumbing, while the people who use the tools every day never touch code.

Key features

• App builder: a drag and drop interface with pre built components for tables, forms and charts, custom React components when you need to extend functionality, and multi-page web apps. Apps run in the browser and can be embedded or shared with external users on the Business plan.
• Data sources: Retool connects to PostgreSQL, MySQL, MongoDB, BigQuery, Snowflake, REST and GraphQL API connections, Google Sheets and many more, so one app can pull data from multiple databases and APIs at once.
• Retool Workflows: scheduled jobs and webhook-triggered automations built from code blocks, for tasks such as nightly syncs, alerts or report generation.
• Retool Database: a built-in PostgreSQL database for data that has no other home yet.
• Retool Mobile: native iOS and Android apps with offline mode, push notifications, barcode scanning and signature capture, distributed white-labelled, as a PWA or through the Retool app (Retool Mobile).
• AI features and agents: AI actions inside apps, AI app generation that can generate apps from a prompt as a starting point, and Retool Agents that run multi-step tasks against your tools, billed by agent runtime hours.
• Enterprise security: role based access controls and audit logs on Business, SSO and source control on Enterprise, and separate environments for staging and production.

Retool pricing

Retool prices by user type. Builders who edit apps pay the most, internal users who only use apps pay less, and external users are priced separately. The plans below come from Retool's pricing page as of September 2026; the page showed euro prices here, and the US dollar figures come from third-party pricing guides that match its structure.

• Free: $0 for up to 5 users, unlimited web and mobile apps, 500 workflow runs a month, 5 GB of data storage and 250 AI credits a month.
• Team: about $10 per builder and $5 per internal user a month billed annually ($12 and $7 monthly), with 5,000 workflow runs, a staging environment and 1,000 AI credits.
• Business: about $50 per builder and $15 per internal user a month billed annually ($65 and $18 monthly), adding audit logging, rich permission controls, external user support and 3,000 AI credits.
• Enterprise: custom pricing with SAML or OpenID Connect SSO, source control, custom branding and dedicated support.

Annual billing on the paid plans saves about 20%. Agents include up to 20 hours a month on the free plan; paid usage is billed by the hour, and the rate varies by AI model.

The cost surprise to check is who counts as a user. Every internal user of a Retool app is billed, not only the builders, so a tool used by 200 support agents costs far more than the builder seats suggest. SSO and source control, which many companies consider critical features, sit on the enterprise plans, not on Business; enterprise pricing is quoted by sales.

Data sources, API integrations and external databases

Retool integrates with the systems a business already runs rather than storing everything itself. You connect an external database such as PostgreSQL, MySQL, SQL Server, MongoDB or Snowflake, or a REST or GraphQL API with an API key or OAuth, and Retool keeps those credentials as resources on the server side, so end users never see them. One app can combine multiple databases and API integrations, for example orders from Postgres, payments from Stripe and tickets from a support tool, and write changes back with the right permissions. Separate environments let teams test against staging data before they touch production resources. This is what lets Retool manage data across many systems from one internal app.

Can you self-host Retool?

Yes. Retool offers self-hosted plans next to Retool Cloud, deployed with Docker or Kubernetes on your own infrastructure, so data stays inside your network. The Free, Team and Business plans can be self-hosted with the same features as the cloud version, while Enterprise is required for unlimited users, SSO and advanced self-host features such as secrets manager integrations with AWS, HashiCorp Vault and GCP. Self-hosting gives more control over data access and compliance, but it also means your team runs upgrades, backups and scaling. Competitor Superblocks points out that a self-hosted Retool requires significant DevOps resources and that new features reach self-hosted instances later than the cloud. Teams that self host Retool on the enterprise plans also get audit logs and role based access controls inside their own network.

Retool for mobile and external users

Retool is best known for web apps used by employees, a kind of business software that rarely needs to look polished, but it covers two other cases. Retool Mobile builds native iOS and Android apps for field teams, with offline mode, push notifications and barcode scanning. Some competitor articles, such as Adalo's, describe Retool as web-only; Retool's own product page contradicts that. External apps let you share Retool apps with customers, vendors or partners, for example a client portal, on the Business plan and above. For polished consumer-facing apps, dedicated app builders remain a better fit.

Where Retool shines — and where it falls short

Strengths:

• Very fast to build internal tools on top of existing databases and APIs.
• Full control with SQL and JavaScript wherever the drag and drop editor stops.
• Covers apps, workflows, a database, native mobile apps and AI agents in one platform.
• Self-hosting and enterprise security for regulated teams that want more control over data access.

Trade-offs:

• Needs technical builders; Retool is low code rather than no code, and non technical users struggle without SQL and JavaScript.
• Per-user pricing for every internal user adds up in large teams.
• SSO and source control only on Enterprise.
• Large apps with heavy queries can slow down in the browser.
• Apps live on Retool's platform; there is no clean code export.

How Retool compares

• Appsmith: an open-source internal tool builder with a similar developer-first approach and a free self-hosted edition.
• DronaHQ: an internal tool builder with unlimited users on its plans.
• UI Bakery: a low code platform for internal apps with AI app generation.
• Microsoft Power Apps: the choice for teams on Microsoft 365 and Dataverse.
• AppSheet: Google's no code app builder for non technical users on Google Workspace.
• OutSystems: enterprise low-code for larger, customer-facing applications.

Is Retool worth it?

Retool is worth it for engineering and operations teams that need internal tools on production data and want to spend their time on logic, not on UI plumbing. A support console or an admin dashboard that would take weeks to hand-code can be ready in days, and the free plan is enough to test it on real data. It is less of a fit for non technical users who want a pure no code drag and drop tool, for simple spreadsheet apps on Google Sheets, for companies that need a low per-user cost across hundreds of internal users, or for polished customer-facing apps. If you want help to build or maintain Retool apps, the low-code agencies and developers on LowCodeDevs can take it on.
