Building a web app to manage and test your app at scale

Hey IndieHackers,

The web app creates and manages different versions of your app at scale. Features in no particular order:

• Make sure your app is working without clicking through screens manually
• Work on a new feature, without breaking the live app
• A/B Test different versions of your app simultaneously for faster feedback

I'm trying to validate this before building, so I don't make the same mistakes as I've done in the past :)

Do you need this app? Have you used something like this before?
