FastGPT
Open-source enterprise AI agent builder with visual workflows and hybrid RAG
FastGPT stands out for on-premise, governable AI agents with a visual workflow builder and hybrid retrieval. Its SSO, RBAC, and LLM auditing are genuine enterprise assets. But sales-led engagement and no visible pricing may deter smaller teams. For quick self-serve needs, consider Dify's cloud tier or OpenAI Assistants; for production RAG with compliance, FastGPT is worth evaluating.

About FastGPT
FastGPT is an open-source enterprise AI agent builder and RAG platform. You create production-grade AI assistants by stacking blocks in a visual workflow, integrating any large language model via API. Hybrid vector-plus-keyword retrieval grounds responses to reduce hallucinations, while data auto-cleansing keeps your knowledge base current. Governance is a core focus: SSO, RBAC, and full LLM lifecycle auditing give compliance-minded teams control. Deployment options include cloud, self-hosted, and private, with turnkey solutions for sales, support, HR, and finance—such as an AI sales assistant, smart ticket routing, resume screening, and expense reimbursement review. With 28,000+ GitHub stars and 1,000+ enterprise customers, FastGPT targets organizations needing secure, controllable AI agents with deep workflow and integration requirements.
Behind the Verdict
FastGPT differentiates through a visual, block-stacking workflow that lets you build complex agents without code, combined with hybrid retrieval (vector plus keyword) to curb hallucinations. The governance layer—SSO, RBAC, full lifecycle auditing—puts it ahead of many competitors for regulated industries. Turnkey solutions (sales assistant, ticket routing, resume screening, expense review) accelerate time-to-value. Weaknesses: no public pricing, sales-led onboarding, and self-hosting may require DevOps expertise. Hobbyists and simple-chatbot projects will find it heavy. Best for enterprises with compliance needs and document-heavy workflows; not ideal for small teams wanting instant self-serve.
