Show HN: I made read receipts for file sharing

Hey HN,

I built SendFast (https://sendfast.app) because I was tired of clunky urls, and not knowing when my files are viewed. Google Drive links are long and annoying, WeTransfer has ads and expirations, and most alternatives don’t tell you if someone actually opened your file.

With SendFast:

- You upload and share files up to 32GB - Get notifications when someone views or downloads your file (no more “Did you get my email?”) - Recipients don’t need an account & can preview files (images/videos/pdf) instantly without ads - Links won’t expire as long as you need them [also working on better pricing and guarantees to make sure this extends down to even free-tier]

It’s built for people who send important files (contracts, pitch decks, legal docs, photos, etc.) and want a simple, reliable alternative that doesn’t lock them into a Big Tech ecosystem.

I’m still improving it, so I’d love any feedback. What do you currently use for sharing large files? Any pain points?
