What it does
A macOS menu bar app that shows every listening dev port with the app or AI agent that opened it, warns when a server is exposed to your LAN, and stops it safely. CLI and MCP server included.
Wharfy shows every listening dev port with the app — or AI agent — that opened it, warns you when a server is exposed to your LAN, and stops it safely. $ wharfy list PORT PID USER PROCESS ← PARENTS 3000 51530 egebilge node ← claude ← zsh ← Terminal 3001 51612 egebilge node ← cursor ← launchd 5432 1201 egebilge docker: papyro-app-db-1 Who opened it The full parent chain, with the starter's real app icon. A port opened by Claude Code says so. One opened by Cursor says so. No more pid archaeology. Dev servers bound to 0.0.0.0 are visible to everyone on your network. Wharfy flags them, and filters the list to just those in one click. SIGTERM, a grace period, then SIGKILL. Tree-kill stops the…from wharfy.dev

Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…
