LLM App Frameworks & SDKs comparisons
Head-to-heads featuring LLM App Frameworks & SDKs tools — at-a-glance tables, benchmarks, and verdicts.
Haystack vs LangGraph
If you need production RAG with hybrid retrieval and multimodal support, pick Haystack. If you must build complex, stateful multi-agent loops with human oversight and low-level control, pick LangGraph. Both are free and open-source, but cater to different core use cases.
Dify vs Langflow vs FastGPT
Choose Dify if you need a fully open-source, self-hosted solution with MCP server publishing and RAG pipelines, ideal for production deployments. Choose Langflow if you want a low-code, team-collaborative platform with Python customization and enterprise cloud hosting for rapid prototyping and iteration.
