Zas
Send files, text and code. It deletes itself in 5 days.
Zas moves files, photos, text and code between your devices and to other people. Nothing to install and no account to start: open zas.red and paste. A universal clipboard: copy on your phone, paste on your computer. Directo sends up to 10 GB device to device. Everything is encrypted on your device before upload and deletes itself in 5 days unless you pin it. Your coding agent (Claude Code, Codex, any MCP client) can send too. Web, Android and iOS. Free to use — a corridor, not a warehouse.
Hi Product Hunt, I'm Sebastián, solo founder in Buenos Aires.
Zas is for the thing you do ten times a day and never think about: getting a file, a photo, a link or a chunk of text from this device to that one. Most of us do it with a WhatsApp message to ourselves, an email to ourselves, or a USB stick. All of those are libraries. Nobody cleans them.
Zas is a hallway instead. Open zas.red, paste or drop something, and it is on your phone. No account and no install to start. Sign in with Google, Apple, an email code or a passkey when you want it to stick. Everything expires after five days, with a small ring on each item counting down — nothing to clean up, nothing left behind.
"Isn't this just AirDrop?" AirDrop stops at Apple. Zas doesn't — any device, any browser (Android to iPhone, phone to laptop), then it clears itself out.
What is under it:
- Content is encrypted on your device before upload. Storage receives encrypted bytes. The service keeps the account, channel, delivery and expiry metadata it needs to sync and delete items. I do not call it end-to-end and I would rather tell you why than have you find out: the account key is derived with help of a server-side service.
- Direct moves up to 10 GB from one browser to another over a live connection, nothing stored, with a 24-hour encrypted fallback if the connection cannot be made.
- Your coding agent (Claude Code, Codex, any MCP client) gets its own identity in Zas: its own keys, a permission per channel, a teal >_ mark on everything it sends. It is never you.
- Web, Android and iOS, in Spanish, Portuguese and English.
Free. No card and no plan to pick.
What I have not built yet: a blocklist and takedown path for abuse, Direct in the native apps, and a simpler agent pairing.
Tell me what breaks and what is unclear. I will be here all day.

Who hunted Zas?
Zas was hunted by Sebastián Fernández Quezada. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
