labring/FastGPT

FastGPT is a knowledge-based platform built on the LLMs, offers a comprehensive suite of out-of-the-box capabilities such as data processing, RAG retrieval, and visual AI workflow orchestration, letting you easily develop and deploy complex question-answering systems without the need for extensive setup or configuration.

FastGPT – An AI‑Agent Building Platform

FastGPT (by the labring organization) is a self‑hosted, open‑source platform for creating and running AI agents. It bundles the usual pieces needed for a Retrieval‑Augmented Generation (RAG) or chatbot‑style application—data ingestion, vector‑store search, model calling, and a visual workflow editor—so you can assemble fairly complex AI‑driven services without writing a lot of glue code.

What it does

Area What FastGPT provides
Application orchestration A Flow visual editor where you can chain together Agent Skills, dialogue workflows, plugin steps, and basic RPA nodes. The UI lets you design multi‑step interactions and expose them as a single app.
Debug & testing Built‑in tools for testing knowledge‑base look‑ups, seeing the full call chain (including model prompts and responses), and annotating or editing references during a conversation.
Knowledge‑base handling Supports multiple vector stores, incremental chunk updates, and a wide range of file types (txt, md, html, pdf, docx, pptx, csv, xlsx) plus URL fetching. It also offers mixed retrieval & re‑ranking and an API‑driven knowledge‑base.
Plugin system Hot‑reloading of system tools, with a roadmap for hot‑updating RAG modules, agent loops, and real‑time generation plugins.
Operations Shareable, no‑login chat windows, one‑click iframe embedding, unified conversation logs with labeling, and basic usage analytics.

How to get it running

  1. Docker quick‑start – Run a single script that pulls a configuration file and then docker compose up -d. After a few seconds the UI is reachable at http://localhost:3000 (default credentials: root / 1234).
  2. Self‑hosted options – Besides Docker you can deploy on Sealos Cloud with a one‑click installer.
  3. Cloud SaaS – If you prefer not to manage infrastructure, FastGPT offers a hosted version at fastgpt.io.
  4. Commercial edition – For enterprises that need extra features or dedicated support, a paid version is available (SaaS is prohibited by the open‑source license).

Ecosystem & related projects

  • fastgpt‑plugin – a repository for extending FastGPT with custom plugins.
  • AI Proxy – a model‑aggregation and load‑balancing service that FastGPT can call.
  • Sealos – the underlying platform used for cluster‑level deployment.
  • SiliconCloud – an open‑source model‑hosting front‑end that can be hooked into FastGPT.

Who might use it?

  • Product teams that want to prototype AI‑augmented workflows (e.g., customer‑support bots, internal knowledge assistants) without building the pipeline from scratch.
  • Developers looking for a visual “low‑code” environment to stitch together LLM calls, vector searches, and external APIs.
  • Enterprises that need a self‑hosted solution for data‑privacy reasons but still want a ready‑made UI and debugging tools.
