When NOT to use langserve

Constraint-first guidance from category fit and live maintenance signals - not marketing copy.

  • When you prefer using frameworks or tools that are not built around Python's ecosystem and require languages like JavaScript or Java.
  • If your project specifically requires a non-FastAPI backend for serving models because of specific performance criteria, constraints, or compatibility issues with FastAPI.
