Share beyond your machine
Turn any running server into a live, branded HTTPS URL — for phone tests, webhooks, and demos. Nothing to install.
Sometimes localhost isn't enough. You need to open the thing on your phone, point a webhook at it, or send someone a link. Pier turns any running server into a live HTTPS URL in one click. No tunnel tool to install, no config file, no account juggling.
From localhost to a URL
Hit Share on a running server and you get back a branded HTTPS link that routes straight to it. Pier runs the tunnel for you and tears it down when you're done. The URL works where localhost doesn't: webhooks, OAuth callbacks, phone browsers, someone else's laptop.
There's also a small inspector that lists the requests coming through the link. It turns "did the webhook fire?" from guesswork into a line on your screen.
Made for agent work too
When a coding agent builds something, the server it started is already sitting in Pier, so sharing it for a look is the same single click. And nothing an agent does goes public on its own — Pier asks you first.
Share links are live in the preview. Join the waitlist for an invite.
Run everything side by side
Start, watch, and stop every dev server, script, and package-manager command — each server on its own myapp.localhost domain.
Provision your local backend
Postgres, Redis, and more in one click — connection string ready, password already in your OS keychain. You never touch Docker.
