PortTracker

Not just "what ports are open?" — "which of my projects are running right now?"

PortTracker is a fast CLI + interactive TUI that lists your listening ports, detects which project they belong to, and lets you kill them by port or project name. Works on macOS and Linux.

Why PortTracker?

There are many port killing tools out there. Here's what makes PortTracker different:

Feature	pt	fkill	killport	kill-port	LazyPorts
Interactive TUI	Yes	Fuzzy list	No	No	Yes
Auto project detection	Yes	No	No	No	No
Kill by project name	Yes	No	No	No	No
Grouped by project	Yes	No	No	No	No
Directory + uptime	Yes	No	No	No	No
Search / filter	Yes	Fuzzy	No	No	Yes
Kill confirmation	Yes	No	No	No	No
Single binary, zero deps	Yes (Go)	No (Node)	Yes (Rust)	No (Node)	Yes (Go)

Most tools answer "kill port 3000". PortTracker answers "what's running, where, and for how long?"
