Marsdrop is privacy-first file sharing. Files are encrypted in your browser with AES-256, sent by link or peer-to-peer, and deleted on your terms — the server never sees your files or keys. Free to fly — send rocket fuel only if you want to.





Hey Product Hunt! I'm Rishabh, the dev behind Marsdrop.
A while back I sent a signed contract over chat, then realized weeks later it was still there — sitting on their servers, readable, forever. "Delete" doesn't delete anything; it just hides the file from you. I wanted to send something that truly vanishes — that not even the service can open.
So I built it.
Marsdrop encrypts your file in the browser before it leaves your device. The key lives only in the share link (after the #, which never reaches a server) — so all my server holds is a blob I genuinely can't read. No accounts, no tracking.
A few things I'm proud of:
- Truly zero-knowledge — the key never touches my server. It's math, not a privacy policy.
- Files self-destruct — on a timer, a download limit, or whenever you revoke them.
- Direct P2P mode — send browser-to-browser, no server in the middle.
- Free — no tiers. Optional tip jar if you want to fuel it.
I built the whole thing solo. This is v1 and I've got big plans — drop a comment with what you'd want to see. Building in public.
Thanks for checking it out! 🚀
The browser-side encryption is a nice touch, files stayed end-to-end encrypted even when I sent a link to a friend. Also appreciate that the server never sees the keys, makes sharing sensitive docs way less stressful.
@adakockana30363 Thank you Ada, this genuinely made my day 🙏 That "less stressful" feeling is exactly what I was chasing , the whole point is that you don't have to trust me, because the keys never reach my server. Really glad it landed for you!
Love the browser-side encryption approach, and the delete-on-your-terms part is what really sets it apart. One thing that would seal the deal for me: add a password or passphrase option on top of the link, so even if the URL leaks the recipient still needs a second factor to decrypt. Would make it usable for truly sensitive stuff.
@abanaltmgzpk Really thoughtful , exactly the right threat to think about 🙏 Love feedback at this level ! keep it coming!
