P2P file sharing app without cloud, free and open-source

Hello reddit! I am P2P engineer so in my free time was working one little side project I'm excited to share, it's called AlterSend. AlterSend is a free, open-source app for sending files directly between your devices, no cloud, no uploads, no size limits. Files transfer peer-to-peer and are end-to-end encrypted, so nothing is ever stored on a server. GitHub: https://github.com/denislupookov/altersend Features: No accounts No servers storing your files End-to-end encrypted No file size limit Cross-platform (desktop + mobile) Open source The idea was to build a good alternative to the established cloud file-transfer apps, without the cloud. How it works, roughly: AlterSend is built on Hyperswarm, which underneath is a Kademlia DHT. For every transfer we generate a random key that acts as a discovery topic, you share that with whoever should receive the files. Each peer announces itself on the DHT under its own node ID, so peers can find each other directly. A handful of public bootstrap nodes serve as the initial entry point and after that peers discover one another through the DHT without relying on any central server. Once two peers connect, the transfer is direct and encrypted end-to-end. Would love to hear your feedback! submitted by /u/AlgoAstronaut [link] [留言]
