Windows shows "Windows protected your PC"?

The installer is not code-signed yet, so Windows SmartScreen may warn you the first time. Click More info, check that the app is Sir, Post, then click Run anyway. You can compare the file with the SHA-256 above.

First time installing? See Desktop app and local agent for what Windows and Android ask on the first install.

Everything works on the web today, on desktop and on your phone. Requests are sent from our server, so public APIs work right away. For localhost and private office addresses, open the desktop app: it also lets the browser reach them through its local agent.
