Hey HN. Built this because LangSmith needs a cloud account just to see my own traces.

pip install opensmith — everything shows up at localhost:7823. SQLite. No accounts.

No config. Fully offline.

800+ downloads in 2 days. Surprised me.

Would love honest feedback from this community.

Hey HN. I built this because LangSmith needs a cloud account to see my own traces.

The full stack is: → @trace decorator on any Python function → autopatch() for OpenAI, Anthropic, LiteLLM, Qdrant, ChromaDB, Pinecone → SQLite at ~/.opensmith/traces.db → Dashboard at localhost:7823

800+ downloads in 2 days.

I have not done any marketing.

Its early in development. I am happy to hear what is missing.
