Install it on your server

Cloud

The easiest way is through the Console: connect a server, then install the app from the catalog.

  1. Sign in to the Keenrig Console

  2. Add a server and run the install command the Console gives you on your VPS

  3. Go to Catalog, pick this app and press Install

Open the ConsoleInstall Keenrig

Whoami echoes back exactly the headers and addresses it receives. That sounds useless right up until routing goes wrong: when a domain lands on the wrong app, or the gateway is not forwarding a header you assumed it forwards, this is the only place you see the truth instead of guessing.

What you would use it for

  • A domain you just added returns the wrong app — install Whoami on that domain to see where requests actually land.
  • Check whether the gateway passes `X-Forwarded-For` and `X-Forwarded-Proto` down to the container, before installing a real app that depends on them.
  • Confirm a new instance receives outside traffic at all, separately from whether an app works.

What Keenrig handles for you

  • The lightest entry in the catalog: 32 MB of memory, small enough to run alongside everything else while you diagnose.
  • Health checked at its own `/health` path rather than `/`, so whatever the root path returns never makes the platform think the app is dead.
  • Fast to install and remove; it holds no data to lose when you delete it.

What it does not do. This is a diagnostic tool, not something to leave running. It prints request headers to anyone who can reach it — take it off a public domain as soon as you have found what you were looking for.
