ToolJet

ToolJet is an open-source low-code platform for building internal tools such as admin panels, dashboards, CRUD apps, and workflows. It provides a drag-and-drop UI builder, integrations to common data sources, and a query/action layer to connect UI components to data and business logic.

Key Features

• Drag-and-drop app builder with pre-built UI components (tables, forms, charts, etc.)
• Connectors for databases, APIs, and SaaS tools; run queries and bind results to components
• JavaScript for transforming data and controlling component behavior
• Authentication and role-based access control (RBAC) for internal app permissions
• Reusable modules/components and app versioning/management features for teams
• Audit/logging and environment configuration options for operational use
• Deployment options including Docker-based self-hosting and Kubernetes setups

Use Cases

• Operations/admin panels for managing users, orders, inventory, or content
• BI-style internal dashboards combining multiple data sources
• Support and engineering tooling (triage consoles, runbooks, internal workflows)

Limitations and Considerations

• Complex logic may still require custom code/services beyond the built-in query layer
• Connector coverage and advanced enterprise controls can vary by edition and release

ToolJet fits teams that want to ship internal tools quickly while keeping control of hosting and extensibility. It is often used as a Retool-style builder for CRUD apps and data-driven internal dashboards with database/API integrations.
