Port discovery
Walks every TCP listener via lsof, dedupes IPv4/IPv6, and tells you the port, PID, command, and cwd.
macOS-first · built for developers
See what's
running.
Run it again.
A native macOS menu-bar app that discovers every process listening on localhost, remembers how you started each one, and gives you run / stop / restart without hunting through terminal tabs.
Localhost, no surprises.
DevDock surfaces the things you actually need when you're juggling four dev servers at 2am.
Run · Stop · Restart
Save how a service was started — DevDock spawns it via $SHELL -ic in the right cwd so nvm & asdf just work.
Captured logs
stdout & stderr stream to per-run log files, viewable in a dialog. No more "where did that error go?".
Instant search
Filter the list by label, port, command, cwd, or project name. ⌘F focuses it in one keystroke.
Signal over noise.
Every process gets sorted into one of three buckets so the things you care about float to the top.
Dev
What you're actually building.
Foreground services launched from a project root — your web server, your API, your database, your background workers.
next dev
cargo run
postgres
redis-server
Tooling
Helpers that keep dev running.
IDE helpers, language servers, container runtimes, ADB, anything inside an .app/Contents/ bundle — visible but tucked under a fold.
rust-analyzer
tsserver
Docker
OrbStack
System
macOS doing macOS things.
Apple daemons and consumer apps that happen to bind a port. Hidden by default, one click away when you want them.

sharingd
Tail the logs. Ask your AI.
The two things you actually do when something breaks — built in, opt-in, local-first.

Local AI suggestions opt-in
Point DevDock at whichever AI CLI you already have installed — it stays local, you stay in control.
Detected a Next.js project at

Suggested command:
pnpm dev on port 3000.
Stale
node still bound to :5173 with no parent shell.
Suggested action: free the port before next launch.
