I have decided to open source this project to increase trust even further. In case you have seen my previous posts, this is an update for berb.app, a WebRTC file sharing app. My goal is simple: send files between devices in real-time without installing crap or uploading to any servers.

It uses WebRTC to allow peer-to-peer sharing, so you can send files to devices on the network using super fast WiFi speed. You can send to anyone on the web though. Drag files, get a download link and send it. Enjoy http://cend.me

Perhaps the easiest way to get a shell on your remote devices wherever they are (even behind NATs and firewalls) -- no VPN required. Offers file transfer right from the terminal itself. Because it is web-based and connects via WebRTC it is better than VPN + SSH in every way: - no setup required on the client machine, it hence works on all OSs and even your phone, - it will always find the shortest-path to your robots, meaning it won’t go through the cloud if you are on the same network as your robot - still end-to-end encrypted - file upload via drag & drop - file download by clicking on…

I’d like to share a open source project I’ve been working on: Weblink, a pure web-based file transfer and chat application built on WebRTC. No downloads or installations are needed—everything works directly in your browser. Key features include: - Works seamlessly as a PWA for sharing files/text through the system - File synchronization and resuming interrupted transfers - Video calling - Clipboard and folder transfer (folders are auto-compressed) Weblink uses a serverless P2P architecture, supporting multiple backends like Firebase and self-hosted WebSocket, and ensures signaling…

Made this to use my laptop terminal session on mobile without data going through a server. tt start -p mypassword → get a URL (qrcode) → open in browser → enter password → connected. Direct webrtc datachannel between your machine and browser. Signaling server is a cloudflare worker, exchanges ~2KB of sdp/ice metadata then gets out of the way. Password never transmitted - argon2id derives 256-bit key locally on both ends. All terminal i/o gets nacl secretbox encryption before hitting the datachannel. double encrypted with dtls underneath but I wanted the relay to see nothing useful…
