In simple English
Restfox lets you test your computer programs by sending messages to web addresses and checking the replies. It runs right on your computer or inside a web browser window. It stores all your work locally so nothing gets sent to an external server. You do not need to pay any money or create an account to use it. It saves you time when you build websites and need to check if your server code works correctly.
