UltraRAG is an open-source rag & knowledge project by OpenBMB (OpenBMB/UltraRAG on GitHub). It has 5,717 GitHub stars and 450 forks, is released under the Apache-2.0 license, and was last updated on GitHub on 7 October 2026.
Map the retrieval and generation steps you need — corpus processing, retriever, reranking, generation, evaluation.
Clone the repo and sync dependencies with uv, choosing core, full or per-module extras.
Point the pipeline at your embedding and LLM providers (for example OpenAI, Qwen or local vLLM) and prepare your corpus.
Execute a bundled example experiment YAML, then open the UI to inspect each step's output.
Compose retrieval, generation and evaluation steps in a few dozen lines of YAML instead of hand-writing orchestration code.
Built as a low-code MCP framework, so pipeline components interact through the Model Context Protocol.
Designed against black-box development: pipeline logic and intermediate results stay inspectable, including in the web UI.
Install only the modules you need with extras — retriever, generation, or the full stack with corpus processing and evaluation.
Ships multimodal support and example pipelines including a lightweight DeepResearch setup.
Ready Docker images (base CPU, base GPU and full GPU) are published on Docker Hub for a fast start.
Clone UltraRAG (shallow) and enter the directory.

Yes — it is open source under the Apache-2.0 license.
It depends on your pipeline: hosted models (OpenAI and similar) need your key, while local models served with vLLM do not.
Those are general application frameworks; UltraRAG specializes in declarative, MCP-based RAG pipelines where every reasoning step remains visible and swappable.
Clone the repo, run uv sync, and execute the sayhello example pipeline.
