Haystack by deepset is an open-source framework for building search systems, question answering, and RAG applications. It uses a modular pipeline architecture where components (retrievers, readers, generators) can be mixed and matched. Haystack 2.0 introduced a cleaner API focused on LLM applications with pipeline serialization and deployment tools.
Key Features
- Modular pipeline architecture
- RAG pipelines
- Document stores integration
- Pipeline serialization
- Evaluation tools
- REST API deployment
- Component marketplace
Pros
- Clean modular design
- Good for search/QA systems
- Production-ready
- Strong typing
Cons
- Smaller community than LangChain
- Fewer integrations
- Learning curve for pipelines
