Workbox

This is cool! I tried to do this in the past with solutions like Jotform etc. but the experience wasn't great. I think your solution might help here. I did find the landing page slightly confusing at first and gave you some recommendations in-context, see https://app.usebubbles.com/058f5d83-9601-4e57-a8e4-508e7a1cc365 --- let me know if this helps.

Technically great: TS implementation, numerous upload sources, various plugins, tree-shakeable and very easy to customise. Also very fast and good support from the maintainers!

This is great! Services like Uploadcare need an API key (so that you can use their backend APIs) to import images from Instagram/Facebook/etc., but with Uppload, it just works! No sign up or API key hassles needed. And it has cool features like importing from Unsplash that no other file uploading widget has.
