How to access your app engine dev server from another machine

I keep forgetting how to do this so I’m writing it down in the vain hope I may commit it to memory.

The problem

You want to access your locally running dev server on another machine on your local network or maybe even from a virtual machine. whatevs.

The solution

Start your dev server with this extra program argument (you can find this under “debug configurations” in eclipse):


Now remember it you stupid brain.

Gradle users

If you’re using Gradle then you need to set it in httpAddress like this:

appengine {

    httpAddress = ""
    httpPort = 8888
    downloadSdk = true
