Feedback on landing page: Remote config for apps

Hi all, 👋

I've been a long time stalker, but this is my first IH post. I've been building mobile apps for quite some time and one thing eventually always pops up:

"Can we make it so that I (PO) can still edit this text afterwards?"
"Can we turn off the feature again after <date>?"
"Can we force user to update to the newest version?"

The solution is usually to dump a simple JSON config file onto an ftp and move on with life. However that JSON often tend to become not so simple anymore after a while (different configs for different app versions, OS etc).

I'm building a tool to simplify this use case. Still working on the initial version, but would love to get your feedback on

1. The problem space: If you're a (mobile/web) developer, have you ever encountered this issue before? Are there better solutions that JSON files that I just missed?

2. Alternatives: For those that have tried other solutions (like Firebase Remote Config), would love to hear what you like and don't like.

3. Can you think of someone that would want this now? (And be happy to sign up for a beta)
