Choose gateway if…
- gateway is primarily TypeScript; langstream is Python.
- Tags unique to gateway: ai-agents, anthropic, language-model, llm.
- When you require access to more than 200 different LLMs through a unified interface, ensuring seamless integration and management in your development projects.
When NOT to use gateway
- When your project only involves a few specific LLMs that don't require a comprehensive, unified SDK; in this case using direct SDKs from those LLM providers could simplify your setup.
- If you are working primarily in languages other than TypeScript and need an SDK that supports those environments natively for better performance or community support.
Choose langstream if…
- langstream is primarily Python; gateway is TypeScript.
- Tags unique to langstream: composability, modular development, python.
- LangStream is a Python-based tool for building robust Language Model (LLM) applications, emphasizing modularity and composability.
When NOT to use langstream
- Last GitHub push was 965 days ago (dormant maintenance, Jan 3, 2024). 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.
