Get started

Go from a local dev server to a public HTTPS URL in under a minute — no flags, no config files.

Five steps

1

Create your account

Sign up at expona.dev and confirm your email. The free plan is enough to get a public URL today.

2

Install the agent

Download the desktop app (or the CLI agent) for your platform. See the Install guide for each OS.

3

Pick a port

Open the app and choose the local port your dev server runs on — 3000, 8080, 5173, whatever you use.

4

Pick a domain

Use a free you.expona.dev subdomain, or attach your own custom domain from the dropdown.

5

Click Expose

Your tunnel goes live on an HTTPS URL in a couple of seconds. Share it, and watch requests stream in.

Prefer the CLI?

Every action has a UI, but the agent also takes a one-liner if you like the terminal:

# expose local port 3000 on a free subdomain
expona expose 3000

# attach your own domain + a passcode
expona expose 3000 --domain app.yoursite.com --passcode hunter2

That's it — the URL prints to your terminal and appears in the web portal, where you can inspect and replay every request.
