Best deepset (Haystack) alternatives
deepset Haystack vs. LangChain: Both Haystack and LangChain are powerful open-source frameworks for building LLM applications. Choose Haystack when your priority is building production-grade, governable, and 'sovereign' AI systems with explicit, inspectable pipelines, especially for enterprise or regulated use cases. Its integrated platform approach (Build, Test, Deploy, Govern) offers a more structured path to production. Opt for LangChain if you prioritize rapid prototyping and access to the largest possible ecosystem of integrations and community components, accepting a more fragmented and less opinionated path to production deployment.
