ToolJet

ToolJet is an open source, low-code application development platform for building internal tools, admin dashboards, data management interfaces, and business applications. With a visual drag-and-drop builder, an extensive library of component widgets, connectivity to dozens of data sources, and workflow automation capabilities, ToolJet enables developers to build and deploy internal applications significantly faster than building from scratch.

The ToolJet Builder provides a canvas-based development environment where applications are assembled from a library of over 50 pre-built components. The component library includes tables, forms, charts, buttons, text inputs, select dropdowns, date pickers, modals, spinners, file uploaders, rich text editors, code editors, maps, calendar views, and many others. Each component's properties are configurable through a sidebar that supports static values, JavaScript expressions, and bindings to query data.

The ToolJet Database (based on PostgreSQL) provides an integrated, visual data table builder for teams that need to store application data without connecting an external database. Tables can be created, columns added, and data managed through a spreadsheet-like interface. The database is accessible through the query system and can be used as the primary data source for simple internal applications.

Data source connectivity in ToolJet covers an extensive range of systems. Relational databases include PostgreSQL, MySQL, SQL Server, MariaDB, Oracle, and SQLite. Cloud databases include BigQuery, Snowflake, Redshift, Databricks, and CockroachDB. NoSQL options include MongoDB, Redis, DynamoDB, Firestore, and Elasticsearch. SaaS integrations include Airtable, Google Sheets, Stripe, GitHub, Slack, Twilio, SendGrid, HubSpot, Salesforce, and many others. REST and GraphQL APIs can be connected for any service without a native integration.

Workflows in ToolJet enable automating business processes using a visual flow builder. Workflows are composed of trigger events connected to action steps including database queries, API calls, conditional logic, loops, and JavaScript code execution. Workflows can be triggered by user interactions in applications, scheduled cron jobs, or incoming webhooks from external systems.

Multiplayer collaboration in ToolJet allows multiple developers to work on the same application simultaneously, with real-time updates visible to all collaborators. Version history tracks changes and enables reverting to previous application states.

Permission management in ToolJet supports groups and roles that control which users can view or edit each application. SSO via Google OAuth, OKTA, and LDAP is available for enterprise deployments. ToolJet can be self-hosted using Docker or Kubernetes, ensuring complete data control and compliance, and ToolJet Cloud provides a managed hosting alternative.
