What is FastGPT?

FastGPT lets you load documents into knowledge bases, test retrieval, and build chat apps, agents and plugin workflows in a visual editor with RPA nodes, user interaction steps and MCP in both directions. Answers show the passages they cite, which you can correct, and every call is logged for debugging and evaluation. It is popular in China, and the documentation is mostly in Chinese, with English and other translations available.

Good fit if

  • You build internal Q&A bots over company documents and want a visual workflow editor.
  • You want to inspect and fix citations and retrieval quality.

Look elsewhere if

  • You need an OSI-approved license: RAGFlow is Apache-2.0.
  • You want broader LLM app building with a larger English community: Dify.

Before you adopt it

The FastGPT Open Source License is Apache 2.0 with added conditions, so it is not open source by the OSI definition. Running a multi-tenant SaaS like FastGPT, or removing its logo and copyright from the console, requires a commercial license from Sealos. A self-hosted setup runs about 14 containers, including PostgreSQL, MongoDB, Redis and MinIO.
