Introduction

ToolJet is an open-source low-code framework to build and deploy custom internal tools. ToolJet can connect to your data sources such as databases ( PostgreSQL, MongoDB, MS SQL Server, Snowflake, , BigQuery, etc ), API/GraphQL endpoints, SaaS tools ( Airtable, Stripe, Google Sheets, etc ) and cloud object storage services ( AWS S3, Google Cloud Storage and Minio ). Once the data sources are connected, ToolJet can run queries on these data sources to fetch and update data. The data fetched from data sources can be visualised and modified using the UI widgets such as tables, charts, forms, etc.

How ToolJet works

ToolJet - List view widget

ToolJet has just 3 fundamental principles for building apps:

  • Connect to data sources: Connect to your existing data sources such as PostgreSQL, MySQL, Firestore, Stripe, Google Sheets, API endpoints, etc.
  • Build queries: ToolJet comes with query builders for all supported data sources. ToolJet also supports the use of custom JavaScript code to transform the query results.
  • Customise widgets: Widgets are the UI components that can be edited using ToolJet's visual app builder ( Eg: tables, charts, forms, etc ). Widgets have events such as on click, on row selected, on page changed, etc. Every UI widget has a dark version.

ToolJet binds together the data sources, queries and widgets to convert business logic into custom applications.
