"All-in-One LLM Tracing, Debugging, and Evaluation with LangSmith"
5/5
What do you like best about LangSmith?

What I like most about LangSmith is that it lets me trace, debug, and evaluate LLM applications all in one place. It offers detailed visibility into model behavior, which makes it easier to spot issues, refine prompts, and keep an eye on overall application performance. I also appreciate its smooth integration with LangChain, along with its support for experiment tracking. Review collected by and hosted on G2.com.

What do you dislike about LangSmith?

One thing I dislike is that there’s a learning curve, especially for users who are new to LLM development and observability tools. Also, some advanced features are only available on paid plans, and setting up evaluations and tracing for more complex applications can take a while. Review collected by and hosted on G2.com.
