Which Should You Pick?

Pick LangGraph if...

  • Higher output quality (9 vs 6)
  • Better value for money (8.5/10)
  • More features (9.5 vs 7)

Developers building complex, stateful, or human-in-the-loop agent workflows where the logic is genuinely a graph -- loops, branches, approvals, retries. Also the right pick for teams already on LangChain who want serious production tracing and evaluation.

Our Verdict

LangGraph is the clear winner here with 8.3/10 vs 6.5/10. Bolt.new isn't bad, but LangGraph outperforms it across the board. Pick Bolt.new only if non-developers who want to quickly prototype a web app idea and don't need production quality.
