ToolJet Overview
ToolJet is a free, open-source low-code platform for building and deploying internal business applications, for Windows, macOS, and Linux, and commonly self-hosted. It lets teams create tools such as dashboards, admin panels, and operational apps by dragging components onto a visual builder and connecting them to data sources. ToolJet supports a broad set of connectors, including databases like PostgreSQL, MySQL, and MongoDB, REST and GraphQL APIs, and various SaaS services, so an app can pull together data from several systems. It allows custom logic through JavaScript and Python-style queries, supports multi-page apps and reusable components, and includes access control and version history for managing apps across a team. Being open source, it can be self-hosted for control over data and deployment, with the core platform free and paid plans available for larger organizations.
