"Langsmith appeared popular, but we had encountered challenges with Langchain from the same company, finding it overly complex for previous NonBioS tooling. We rewrote our systems to remove dependencies on Langchain and chose not to proceed with Langsmith as it seemed strongly coupled with Langchain."

I've never really used Langchain, but setup Langsmith with my own project quite quickly. It's very similar to setting up Langfuse, activated with a wrapper around the OpenAI library. (Though I haven't looked into the metadata and tracing yet.)

Functionally the two seem very similar. I'm looking at both and am having a hard time figuring out differences.
