https://www.instantpreview.dev/ is like an instant, temporary Netlify or Vercel or Cloudflare Pages etc.
The difference? No hassle (no account needed) but also not permanent. Uploaded website expires after ~2 hrs
Why build it?
I have several projects where I generate static website. I often want to preview it before deploying.
Both Vercel and Netlify have cli that allows creating a preview but there's a lot of ceremony (need an account, need to create a project, need to create access token, keep the tokens secret).
So I made Instant Preview where you don't need any of that. Just upload files either by drag&drop in the browser or from cmd-line with curl and I'll create a private (hosted under random url), temporary (expires in ~2 hrs) preview of a static website.
It's not a web hosting service, just for previews. That's why expires in 2 hrs.
Can also upload from code (do a POST to https://www.instantpreview.dev/upload with either form-encoded name/content or raw ZIP file). Will return a URL for the content.
Concept inspired by transfer.sh, except for static websites and not files.
