PortWisp
Developer preview Localhost, with a way out

A public URL for
the server on your laptop.

PortWisp carries HTTP traffic through one encrypted outbound tunnel to a fixed service on your machine. No router changes. No mystery configuration.

$ curl -fsSL https://get.wispbridge.com/install.sh | sh
$ portwisp http 3000

Install the client, point it at a local port, and share the generated URL.

How it works

One command.
One narrow path in.

  1. 01

    Start locally

    Point PortWisp at a loopback HTTP port or URL selected by you.

  2. 02

    Connect outward

    The agent opens an encrypted connection to the PortWisp relay.

  3. 03

    Share the URL

    Requests to your temporary hostname travel back through that tunnel.

Plans

Random by default.
Stable when you need it.

Free$0

Start a tunnel with a randomly generated hostname that keeps public traffic temporary.

  • One active tunnel
  • Random temporary subdomain
  • HTTP forwarding
Start free →
Paid plan
Stable$10/mo

Choose one subdomain and keep it across reconnects while your plan is active.

  • One active tunnel
  • Chosen stable subdomain
  • HTTP forwarding
Choose Stable →

Plans are billed monthly. Stable hostname reservations require an active paid subscription.

01 / Fixed target

The relay can’t redirect your agent.

Your local destination is fixed at startup. A remote message never gets to choose a new address.

02 / Private by default

Loopback means loopback.

PortWisp defaults to 127.0.0.1 and never silently opens a listener to your network.

03 / Ephemeral

A tunnel, not a data warehouse.

Request bodies are not stored or replayed. The early service is designed around temporary hostnames.

04 / Observable

See what reaches your app.

A focused terminal interface shows request metadata, status, timing, and transfer totals.

Built for webhook debugging, demos, mobile testing, and the small moments when localhost needs an audience.
