Self-contained Web App with Persistent Data Packaging
Problem
Users want to bundle an HTML Web app together with its data into a single portable file for offline use, eliminating reliance on external hosting and simplifying sharing, but current solutions lack effective merging capabilities and collaboration support.
Pain points
- Sharing a complete Web app and its data without external servers
- Merging different versions of data files when multiple users collaborate
- Frequent state updates requiring the entire file to be re-transferred
Questions to verify
- Does the target user prefer offline usage over real-time collaboration?
- Is merging different users' data copies the primary pain point?
- Would they accept re-sending the whole file rather than finding a hosting solution?
Evidence

building HTML pages is really simple now, but trying to save data required hosting it somewhere, and sharing it afterwards was not easy.
fact · sourcepost
User data can either be saved as a localStorage key/value store or via a MongoDB-inspired collections API as documents, saved in a table in the file.

If your app needs to update and preserve state (using SQLite or any other DB), it is probably not something you want to pass around as a bundled file.
