Born from the world's smartest spider

How it works
The Hunt, in three moves
A real Portia spider stalks for hours, plans the perfect angle, then strikes in a single leap. Your terminal deserves the same discipline.
02
The Trap
EADDRINUSE detected
The instant a process crashes with a port collision, Portia identifies the offender, the PID, and the exact socket holding the port hostage.
03
The Strike
One-click kill
A native notification slides in. Click Strike and the blocking process is gone. No terminal, no lsof, no fumbling.
Tech specs
Built like the spider it's named after
