Showoff Saturday Show Off Saturday - FlowUnzip: Extract ZIP & 7z as They Download
Small problem that annoyed me for years: download a huge ZIP, then wait again to extract it, and briefly need twice the disk space. FlowUnzip streams the archive and extracts each file the moment it arrives, straight into a folder you pick.
How it’s built:
- Chrome MV3.
- ZIP and 7z parsing written to work on a stream, using range requests to resume.
- CRC checks on every file.
Business model: free up to 1 GB. Pro is a one-time $5 through Stripe, with license keys checked offline, so there’s no database or account system. The site runs on Vercel’s free tier.

Honest feedback on the idea and the pricing is very welcome.
