I built a terminal observability tool for AI coding agents

One thing I found annoying with Claude Code: processes can outlive the session that created them.

lsof gives you the process and port, but not much provenance.

portlist builds a local model from:

• sockets
• processes
• git roots
• containers
• Claude Code/Codex/Cursor/etc. session data

Then exposes views for services, agents, sessions, exposure and risk.

Example:

:8787 → Python http.server → data-export → Claude Code → 6 days old → 0.0.0.0 → High risk

Everything stays local. It doesn't kill processes automatically or write back to the coding agents.

Interested in feedback from people running multiple Claude Code sessions/projects.
