Experiments
Build and test new features here before they go anywhere near the platform.
!
Isolated by convention, not by the database. This page uses the same Supabase login as the platform, so anything you run from a prototype can read or write real data. Test against non-production records.
Files
Upload HTML pages to try them here. Add their CSS, JS and images too, and the preview will wire them together.
drop files here
.html, .css, .js, images, fonts, .json — up to 25 MB each.
Dropping or choosing a folder keeps its structure.

no files
Saved in this browser only (IndexedDB), so they stay after a reload but aren't uploaded anywhere.
Preview is isolated by default: a page can't see your platform login, so pages that need Supabase will show errors until you tick "use my login" in the preview bar. Only turn that on for files you wrote or trust.
Links between uploaded pages work. JavaScript redirects (window.location) and fetch() of local files don't.
