File transfer with no cloud storage, no account, no limits
AlterSend sends files directly between devices - P2P, E2EE, no cloud storage, no account, no size limits. Open source and cross-platform: mobile + desktop. Share a code or scan a QR, and files stream straight across.
I'm Denis. I built AlterSend because sending a big file to someone is still way harder than it should be. You upload it to WeTransfer or Google Drive, wait, hit a size limit, send a link, and your file ends up on a server that isn't yours. It's slow, it's capped, and it's not private.
AlterSend sends files straight from your device to the other person's. No upload step, no account, no size limit, end-to-end encrypted. Works anywhere - same room or another country.
We released a month ago and it's going better than I hoped: 7,000+ downloads, almost 1,000 GitHub stars, and a lot of great feedback from users that's helping me decide what to build next.
How it works: • Each transfer creates a random 32-byte key - that's the join code you share with the receiver • Devices find each other through a public DHT using a hash of that key - the key itself never leaves your devices • The connection is encrypted end to end. If a direct connection isn't possible, a relay passes the encrypted stream along - it can't read your files and doesn't store anything • When you disconnect, everything is wiped — nothing is stored anywhere
It's open source (Apache-2.0), free, and there are no accounts.
I'd love honest feedback - especially: what would it take for you to stop using WeTransfer, Drive links, or USB sticks? I'll be in the comments all day. 🙌
