ToolJet is an open-source low-code platform for building internal tools quickly. Its visual builder includes over 50 UI components — tables, charts, forms, maps, calendars, kanban boards — that connect to virtually any data source through built-in connectors.
The platform supports data connections to PostgreSQL, MySQL, MongoDB, Elasticsearch, REST APIs, GraphQL, Google Sheets, Stripe, Slack, Twilio, and many more. Custom JavaScript and Python transformations enable complex business logic. ToolJet also includes a built-in database for simple use cases.
ToolJet is open source under the AGPL v3 license. Self-hosted deployment is free with unlimited users. ToolJet Cloud offers a free tier and paid plans starting at $20/user/month.
