FastGPT
An AI agent building platform with out-of-the-box data processing and model-calling capabilities, letting users assemble complex question-answering applications through a visual workflow editor.
FastGPT provides ready-to-use data processing and retrieval-augmented generation retrieval alongside model calling, and lets a user compose these into more complex applications through a visual flow-based workflow editor rather than custom integration code. It can be started quickly with Docker using a guided configuration prompt.
Its ecosystem includes a plugin system (FastGPT-plugin), an AI Proxy component for aggregating and load-balancing calls across multiple model providers, and Sealos for deploying clustered applications; third-party services are also listed as compatible.
Its source is published under the FastGPT Open Source License, which permits direct commercial use as a backend service but does not permit offering it as a SaaS product without a separate commercial license, and requires copyright notices to be kept in any commercial deployment.
It is written in TypeScript.
