Did you have anyone in mind specifically when building this?
1. Indie hackers validating ideas — need a working form/API for their landing page before committing to a "real" backend
2. No-code builders on Webflow/Framer/Carrd who want dynamic data but don't want to learn Firebase
3. Freelancers (like me) who keep getting "can you make this spreadsheet accessible via API" requests from clients
4. Internal tools teams who already have data in Sheets and just need to expose it to a dashboard
The common thread: situations where the data naturally lives in a spreadsheet, and spinning up a proper database feels like overkill.
