Choose langstream if…
- langstream is primarily Python; langchaingo is Go.
- 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 964 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.
Choose langchaingo if…
- langchaingo is primarily Go; langstream is Python.
- Tags unique to langchaingo: ai, go, golang, langchain.
- - You are working on a project that requires LLM-based capabilities, but prefer to code in Go.
When NOT to use langchaingo
- - If your project strictly adheres to another programming language where other implementations of LangChain are available.
- - When your application requires heavy customization at the framework level that might not be directly supported within LangChainGo’s current implementation.
