Cognita

Summary

TrueFoundry's Cognita is a free, self-hosted RAG framework for teams building document-search-powered AI applications without vendor lock-in.

Cognita lets data science and platform engineering teams assemble retrieval-augmented generation systems by connecting pluggable components—vector databases, embedding models, rerankers—without writing infrastructure code. The problem it solves: production RAG deployment is fragmented across commercial APIs and open-source libraries, forcing teams to choose between convenience and control. The headline differentiator is its ability to run entirely via docker-compose on local infrastructure while hosting multiple RAG instances in a single application, making it viable for organizations with sensitive document collections. It's free. The honest catch: you're limited to Qdrant or SingleStore for vector storage today, and production use requires standing up separate LLM and embedding model services yourself—so the 'free' price tag assumes you can manage containerized infrastructure.

Bottom line: *Use this if your team can containerize infrastructure and needs to avoid cloud APIs for data; skip it if you want a fully managed SaaS solution.*
