AgentBox – a zero-dependency local observability dashboard for smolagents

[pujaaaaaa]

I built a tiny local observability tool for smolagents and wanted to share.

I kept spinning up Postgres + Docker just to check token usage and
latency on local agent runs, which felt like massive overkill. So I
built AgentBox — single Python file, zero dependencies, logs every
run to local SQLite, and gives you a live dashboard at localhost:8888.

It auto-detects the .monitor object on smolagents runs for token
counts and cost tracking, no config needed. Nothing leaves your
machine — no signup, no cloud.

Currently smolagents-specific, planning LangChain/CrewAI adapters
next. Would love feedback from people running agents locally — is
this useful, and what's missing?
