About ToolJet

ToolJet is an open-source platform for creating internal software, including admin panels, dashboards and operational apps that sit on top of your existing databases, APIs and SaaS systems. Apps are assembled visually in a builder, so teams can ship tools without writing a full front end.

AI plays a large role. ToolJet AI turns a text description into pages, queries and components, and a Model Context Protocol server lets coding agents such as Claude Code and Codex build and modify ToolJet apps directly. Agents work against the platform's real component and data contracts, so the output is an ordinary ToolJet app that the team can keep editing in the visual builder with the same permissions, environments and version history. Workflows and AI agents are part of the offering.

You can self-host ToolJet or use ToolJet Cloud, and the open-source foundation is AGPL-3.0 licensed with a JavaScript and TypeScript codebase. It targets teams that need internal software quickly and want an open-source option with a managed alternative.
