Retool

Retool is a platform for rapidly building, deploying, and managing internal business applications using a unified development environment. It allows teams to connect to virtually any data source, including SQL and NoSQL databases, REST and GraphQL APIs, third-party SaaS tools, and large language models (LLMs). Users can assemble interfaces with a drag-and-drop component library—tables, forms, charts, buttons, and more—while writing JavaScript or SQL where needed for custom logic, data transformations, and workflows.

Retool supports role-based access control, environment management, and versioning, making it suitable for production-grade internal tools. It includes workflow automation to run backend jobs on schedules or triggers, as well as query editors, debugging tools, and audit logs for reliability and governance. AI features enable use cases such as natural language querying of data, AI-assisted form filling, content generation, and integrating custom LLMs into internal apps.
