Expona is the UI-first way to share localhost. Pick a port, pick a domain, click Expose — your app is live on a public HTTPS URL in seconds. These guides cover installing the agent and configuring tunnels, domains, passcodes and team access.

How Expona works

The Expona agent runs on your machine and keeps a secure outbound connection to the Expona edge. When a request hits your public URL, the edge forwards it down that connection to your local port and streams the response back. Because the connection is outbound, you never open a firewall port or expose your IP.

Everything you can do from the CLI you can also do from the desktop app and web portal — choosing a port, attaching a custom domain, adding a passcode, and inspecting or replaying requests. That's the whole idea: select and expose, no flags to memorise.
