FastGPT

No-code knowledge base platform with visual AI workflow and built-in RAG

freeupdated Aug 16, 2026

FastGPT is an open-source no-code AI knowledge base platform with 27,000+ GitHub stars and 500,000+ users worldwide. It combines visual workflow orchestration, built-in RAG pipelines, QA-pair extraction, and API-aligned completions into a single deployable stack that runs on just 2GB RAM via Docker one-liner deployment.

FastGPT provides a complete platform for building intelligent chatbots and knowledge-based applications without writing code. The visual workflow editor lets users design complex AI pipelines by connecting nodes for data processing, retrieval, LLM calls, and conditional logic. Built-in RAG capabilities handle document ingestion, chunking, embedding, and hybrid retrieval out of the box, eliminating the need to assemble separate tools for each step of the retrieval-augmented generation pipeline.

A distinctive feature is the automatic QA-pair extraction system that transforms uploaded documents into structured question-answer datasets optimized for retrieval accuracy. This approach consistently outperforms naive chunking strategies by preserving the semantic structure of source material. The platform supports multiple LLM providers through an OpenAI-compatible API interface, enabling users to switch between models without modifying their workflows.

FastGPT has achieved massive adoption in the Chinese developer ecosystem with over 500,000 users, while remaining relatively unknown in Western developer circles. The platform runs remarkably efficiently on just 2GB RAM, making it deployable on modest hardware. Docker one-liner deployment gets a fully functional instance running in minutes. Enterprise features include multi-tenant support, usage analytics, and custom branding. The project represents a significant gap in English-language developer directories despite its scale and maturity.

hf-agents

One-command local coding agent that auto-detects your hardware and picks the best model

hf-agents is a Hugging Face CLI extension that detects your hardware, recommends the best GGUF model using llmfit, and launches a local coding agent in a single command. It collapses the multi-step local LLM setup into hf agents run pi, automatically handling hardware profiling, model download, inference server startup, and coding agent activation.

NocoBase

Extensibility-first open-source no-code/low-code platform for business apps

NocoBase is an open-source, self-hosted no-code and low-code platform built around a data-model-driven architecture and plugin-based microkernel. Unlike form-centric no-code tools, it separates data structure from UI, enabling unlimited block types and views per data collection. All functionality is delivered through plugins similar to WordPress. Features include AI Employees for in-app automation, visual workflow builder, RBAC permissions, and automatic REST/GraphQL API generation.
