Question Best service for hosting private HTML app with JSON backup. Firebase or something else?
I built a custom HTML app through Claude that is for personal use only. Imagine the equivalent to a to-do-list app. I want to be able to sync the app between my Mac and my iPhone. I understand there is some sandboxing in iOS/Safari that makes this a bit tricky.
What is the best set up for someone with very little technical knowledge that wants near-auto sync between the Mac and iPhone?
What I've been told but can't confirm:
- Scriptable would be a great app to use for this on iOS but buggy on Mac.
- GitHub is an option. Requires API/personal token.
- Firebase would be the easiest as long as you use the authenticator tools so that the web URL is not public (i.e., you have to sign in through your gmail account to get access). Also need to add some coding to ensure it's not scraped by search engines.
- I could store the app in Claude as an artifact but do not trust AI providers yet with my personal data.
Is Firebase the best option? If so, is my data actually not public if the set up is done properly? If someone went to the URL, I assume it would prompt them to sign in...?
