The short answer

Retool and Appsmith are both drag-and-drop builders for internal tools wired to databases and APIs with SQL and JavaScript. Retool is closed source with a larger, more polished component library and per-builder plus per-user pricing. Appsmith is Apache-licensed and free to self-host, which is why many teams choose it. Pick Retool for breadth and polish; pick Appsmith for open source and lower cost at scale.

Appsmith or Retool: our take

The way of working is nearly the same. Developers drop tables, forms, charts and modals onto a canvas, connect them to data sources, and write JavaScript to glue the logic together. Retool connects to almost any source, from Postgres and Snowflake to REST, GraphQL and SaaS APIs, and adds Workflows for scheduled jobs, a hosted Retool Database, mobile apps, customer-facing portals and AI agents. Appsmith covers common databases such as Postgres, MySQL and MongoDB plus any REST or GraphQL API, supports Git-based version control for apps, and has added workflows and an AI assistant. Its widget set is smaller and less polished, and large apps can feel sluggish.

Licensing and deployment are the clearest split. Appsmith's Community Edition is free and open source under Apache-2.0, so a company can self-host it on Docker or Kubernetes at no licence cost and keep data in its network. Retool can also run self-hosted or even air-gapped, but it is a commercial product and teams depend on its roadmap. On the cloud, Retool's free plan is $0 per builder, then $10 (Team) / $50 (Business) per builder/month plus $5 (Team) / $15 (Business) per user/month for internal users, so costs grow as more employees use the apps. Appsmith's cloud is free for up to 5 users, with a Business plan at $15 per user/month; single sign-on and audit logs need paid plans.

Retool suits engineering-led companies building many internal tools on production systems, where a richer component library and wide connector support save developer time, and where the budget can absorb per-user fees. Appsmith suits teams that want a Retool-style builder they control, need self-hosting without a licence bill, or expect a large number of internal users. Both assume comfort with SQL and JavaScript, so neither is aimed at non-technical builders.

What is Appsmith?

Appsmith is one of the most popular open-source alternatives to Retool. Developers drag widgets such as tables, forms, charts and modals onto a canvas, connect them to databases like Postgres, MySQL and MongoDB or to any REST or GraphQL API, and write JavaScript for logic between them. Apps can be versioned with Git, moved between environments and embedded elsewhere, and newer releases add workflows and an AI assistant for generating queries and code. Because the Community Edition is Apache-licensed, companies can self-host it on Docker or Kubernetes at no cost and keep data inside their network, which is the main reason many choose it over closed platforms. The hosted cloud has a free plan for up to five users, a Business plan priced per user, and an Enterprise plan for large deployments with single sign-on and audit logs. It runs in the browser. The widget set is smaller and less polished than Retool's, and complex apps can feel slower.

What is Retool?

Retool lets developers assemble internal tools by dragging tables, forms, charts and buttons onto a canvas and wiring them to databases and APIs with SQL and JavaScript. It connects to almost any data source, from Postgres and Snowflake to REST, GraphQL and SaaS APIs, and adds Workflows for scheduled jobs, a hosted Retool Database, mobile apps, customer-facing portals and AI agents. Engineering and operations teams use it for admin panels, support consoles, approval queues and back-office dashboards that would otherwise take weeks to code. Pricing separates builders from end users: there is a free plan for small teams, then Team, Business and Enterprise tiers charged per builder and per internal user per month, with external users priced separately. It runs in the cloud, self-hosted or even air-gapped, which makes it acceptable to security-conscious companies. It assumes comfort with SQL and JavaScript, and costs grow quickly as more employees use the apps.
