When NOT to use langstream
Constraint-first guidance from category fit and live maintenance signals - not marketing copy.
- Last GitHub push was Jan 3, 2024 (dormant maintenance). Validate activity before betting a new project on langstream.
- Developer Tools: A gateway is overkill when you're pinned to a single provider and model.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
