Ragna review
A self-hosted RAG framework with Python and REST APIs plus a browser UI.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Ragna is an open-source RAG orchestration framework from Quansight for developers experimenting with and deploying retrieval-augmented generation applications. Its Python API supports work with RAG components and LLMs, while a REST API lets teams build custom RAG web applications. A browser UI provides a way to configure LLMs, upload documents, and chat. It is a fit for teams that want a self-hosted RAG API and UI, rather than a broader framework for orchestrating varied LLM application patterns.
Ragna’s ecosystem is centered on connecting language models with document retrieval. Built-in assistants support OpenAI, Anthropic, Google, Cohere, and AI21 Labs; source storage options include Chroma and LanceDB. Developers can also create custom assistant and source-storage components. Document handlers cover TXT, Markdown, PDF, DOCX, and PPTX files. That combination gives teams room to explore retrieval choices and connect hosted model APIs or locally run models, while keeping the work focused on RAG rather than wider orchestration needs.
The framework is installed locally with pip or conda and supports configurable authentication, API, UI, and database settings. Documentation covers Python workflows, REST endpoints, UI usage, configuration, and custom components, with docs and community listed as support channels. Ragna is free and open source, and its published description characterizes the project as early-stage. Teams comfortable with self-hosting and evaluating a developing RAG framework may find its APIs and UI useful; teams seeking a mature, broad orchestration layer or a vendor-hosted service should look elsewhere.
