What LangSmith is for
LangSmith is one of 61 tools in our MLOps, Vector DBs & AI Infrastructure list. Tracing and evaluation for LLM apps.
This layer runs AI in production: vector databases, serving, monitoring, evaluation and data pipelines. Most teams need less of it at the start than vendor marketing suggests.
What to check before choosing LangSmith
- Real scale needs: a simple database extension may be enough at low volume.
- Observability for tracing prompts, costs and failures.
- Whether you can self-host or migrate, and how much operational work that adds.
Avoid adopting a full platform before you have a working use case. Infrastructure bought early tends to shape the product around the tool rather than the problem.
