Get the tropa agent

One small binary, no dependencies — it runs next to your app and forwards a port you're already serving. Download it, or let the one-line installer set it up and connect for you.

Three steps to a public URL

1Start your app

Run your service locally as usual — say a dev server on localhost:3000. tropa forwards to it; it doesn't take the port.

2Connect once

Create a workspace or sign in to get a key, then run tropa up 3000 --relay wss://tropa.doshka.me --token <key>. The relay and key are saved.

3After that, just

tropa 3000 — the subdomain is auto-named from your folder. Use tropa api=8080 to name it yourself, or tropa service to keep it running at login.

Every binary ships with a SHA-256 checksum; the installers verify it automatically. On macOS/Linux, make a manual download executable with chmod +x tropa and move it into your PATH.
