FastGPT

FastGPT is an AI Agent building platform from labring that combines data processing, model calling, RAG retrieval, and visual workflow orchestration. It is available as a cloud service, a community self-hosted edition deployable with Docker or Sealos, and a commercial edition with additional support. The latest release listed is v4.17.2.

What It Is

FastGPT lets teams build knowledge-based question-answering systems and agents without extensive setup. Users import documents into knowledge bases, then compose conversational or plugin workflows in a visual Flow editor to produce deployable AI applications.

Workflow and Knowledge Base

The README lists agent skill orchestration, chat and plugin workflows (including basic RPA nodes), user interaction nodes, and two-way MCP support. Knowledge bases can be reused and mixed across apps, and chunks can be edited or deleted. Import supports manual input, direct chunking, and QA splitting, with file formats including TXT, MD, HTML, PDF, Docx, PPTX, CSV and XLSX, plus URL reading and an API knowledge base. Retrieval uses hybrid search with reranking.

Debugging and Operations

Developers can test knowledge base searches, view and edit cited references during chats, inspect full call-chain logs, and run application evaluations. Operational features include login-free share windows, one-click iframe embedding, unified conversation logs with annotation, and application operation logs. The homepage states it supports SSO and RBAC for enterprise portals and model integration with auditing.

Deployment and Licensing

A Docker install script pulls configuration, after which the app runs at localhost:3000. The license is Apache 2.0 with extra conditions: commercial use is permitted, but operating a multi-tenant SaaS service or removing the logo and copyright information requires a commercial license.
