ToolJet

Retool's job, self-hosted: ToolJet is an open-source low-code platform for building internal tools, dashboards, and admin panels. Apps are assembled in a drag-and-drop visual builder with 60+ responsive components, including tables, charts, forms, and lists, and connected to 80+ data sources: PostgreSQL, MySQL, MongoDB, REST and GraphQL APIs, cloud storage, and common SaaS tools. When visual configuration is not enough, you can run JavaScript or Python inline for queries and transformations. A built-in no-code database (ToolJet Database) covers apps that need their own tables without provisioning an external database, Workflows add node-based automation for background jobs with dedicated worker containers and a Redis-backed queue, and multi-page apps with multiplayer editing, inline comments, and mentions support team development. Security is designed for internal data: credentials are AES-256-GCM encrypted, data flows proxy-only through your server so database contents never reach a third-party cloud, and granular per-app access control plus SSO gate each tool. Where Retool-style platforms bill per builder and sometimes per end user, the self-hosted Community Edition serves unlimited builders and users at hosting cost, and full source availability means the platform itself can be forked, audited, and extended. The stack is Node.js and React on PostgreSQL, deployed via Docker.

Benefits

  • No Per-User or Per-End-User Charges
  • Retool-style platforms bill per builder and sometimes per end user. Self-hosted ToolJet Community Edition serves unlimited builders and users at hosting cost.
  • Data Never Leaves Your Network
  • Queries execute through your instance with proxy-only data flow and AES-256-GCM encrypted credentials, so database contents are never exposed to a third-party cloud.
  • Visual Speed, Code Depth
  • Common CRUD screens assemble in minutes from components, while inline JavaScript and Python handle the transformations and business logic visual tools cannot express.
  • An Auditable Exit Strategy
  • Full source availability means you can fork, audit, and extend the platform, an option proprietary internal-tool builders do not offer.

Features
