Complete visibility into every bound port
Never lose a port fight again.
A live registry of every port across your machines and environments — with reservations, approvals, and conflict alerts so two services never fight over the same number again.

Everything you need, nothing you don’t
One live registry
Every bound port across every machine and environment, discovered automatically and kept current — no more grepping netstat on ten boxes.
Reserve before you build
Claim a port for a service with an approval workflow and an expiration, so nothing squats on a number it isn't using.
Conflicts, caught early
The moment two services want the same port, PortsMapper flags it and pings your chat and incident tools.
Audit-ready by default
Full change history and reporting — who reserved what, when, and why — ready for the next review.
Access you control
Role-based permissions and self-hosted collectors keep sensitive environments in your hands.
Fits your stack
Webhooks and integrations wire PortsMapper into the tools your team already runs.
It already knows what's running
Point PortsMapper at your fleet and it inventories every listening port on every host — then keeps that map live as services come and go.
Stop collisions before they ship
Conflicts don't wait for business hours. PortsMapper watches the registry and escalates the instant two services target the same port — with the context to fix it fast.
