FastGPT
An open-source platform from the Sealos team for building knowledge-base question answering and AI agents with visual workflows, RAG retrieval and data processing, offered as a cloud service or self-hosted.
About FastGPT
Building a question-answering system over company documents needs document ingestion, retrieval, model wiring and a workflow layer, which is a lot of glue code to assemble from scratch.
Who it’s for
- Teams building internal knowledge-base assistants or customer-service bots over their own documents
- Developers who want a self-hosted visual workflow builder for agents with any model
When to consider it
Consider FastGPT when you want to build RAG question answering and agent workflows visually, connect your own models, and choose between a hosted plan and a self-hosted community edition.
Tradeoffs & limitations
- Cloud plans are priced in yuan: Free (100 AI credits, 1 team member, 10 agents, 3 knowledge bases), Basic at ¥99 per month and Advanced at ¥599 per month; the free self-hosted community edition is limited to single-user use, and multi-workspace, SSO and full commercial rights need the paid commercial edition.
- Licensed under Apache 2.0 with extra conditions: running a multi-tenant SaaS similar to FastGPT or removing the logo and copyright from the console requires a commercial licence.
