I built a tool to instantly share web projects without deploying

As a CS student, every time I wanted to show something I built, I had to either deploy it, screen share, or send files over WhatsApp.
So I built RunZip.
Drop a ZIP file, get a live URL and QR code instantly. No login, no setup, no account. Files auto delete after 24 hours.
I built it with Node.js, Express, and Vanilla JS. Also made a desktop version with Electron.

Would love feedback from the community. Is this useful to you? What would you improve?"
Dev.to is more relaxed than Reddit. Links are fine, longer posts are welcome, and developers there genuinely give good feedback.
