GamePusher is a tool for Windows that helps you upload your builds to more game platforms, faster.
Steam, Oculus, itch.io.
Every gaming platform offers a command-line tool for uploading your game. These tools are faster and less buggy than UI-based tools those platforms offer (if they even have one). However, command-line tools are hard to use.
GamePusher has a nice interface where you can specify your build, release channel, and anything else offered by platforms' command line tools. Also, it saves all the data you enter for next time (except passwords, if you say so in Settings), and checks for errors. Then, when you press 'Upload', it opens a cmd prompt already running the correct command.
That's all it does.
