ToolJet is an **open-source low-code framework** to build and deploy internal tools quickly without much effort from the engineering teams. You can connect to your data sources such as databases ( like PostgreSQL, MongoDB, Elasticsearch, etc ), API endpoints ( ToolJet supports importing OpenAPI spec & OAuth2 authorization) and external services ( like Stripe, Slack, Google Sheets ) and use our pre-built UI widgets to build internal tools.
The easiest way to get started with ToolJet is by creating a [ToolJet Cloud](https://tooljet.io) account. ToolJet Cloud offers a hosted solution of ToolJet. If you want to self-host TooJet, please proceed to [deployment documentation](https://docs.tooljet.io/docs/setup/architecture).
