ToolJet

ToolJet is an open-source low-code platform that enables developers and business users to build and deploy internal tools, dashboards, and admin panels rapidly without extensive frontend development. Founded in 2021 by Navaneeth K P, ToolJet has gained significant traction with over 35,000 GitHub stars, positioning it as a leading open-source alternative to proprietary low-code platforms like Retool and Appsmith. The platform features a drag-and-drop visual builder with over 50 pre-built UI widgets including tables, forms, charts, buttons, text inputs, dropdowns, date pickers, Kanban boards, calendars, maps, and rich text editors, which can be connected to over 50 data sources including PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, REST APIs, GraphQL, Google Sheets, Airtable, Stripe, S3, SMTP, and Snowflake. ToolJet's component architecture supports JavaScript transformations, event handlers, and custom queries, enabling complex business logic without writing custom backend code. The platform includes built-in multi-tenancy support with role-based access control (RBAC), granular widget-level permissions, group management, and audit logs for enterprise governance. ToolJet can be deployed as a fully managed SaaS (ToolJet Cloud) or self-hosted on Docker, Kubernetes, Helm, AWS EC2, Google Cloud Run, or on-premises infrastructure, with PostgreSQL as the metadata database. The open-source Community Edition is available under the AGPL v3 license, while the Enterprise Edition adds features like single sign-on (SAML, OIDC, Google Workspace), custom CSS branding, white-labeling, multi-environment deployment, and priority support. ToolJet is used by thousands of organizations to build customer support dashboards, inventory management systems, HR portals, and operational admin panels.
