Pairlane

What it does

Pairlane is P2P file transfer: share a link, drop a file, and it goes straight to the recipient. No accounts, no uploads, no server-side storage. Private by default (end-to-end encrypted). Works in browser or CLI.

Transfer files directly between devices via WebRTC. No server upload, peer-to-peer only.

Transfer directly between devices without uploading to a server. Only signaling goes through thefrom getpairlane.com

In the maker’s words, at launch

Hi HN — I built Pairlane, a WebRTC-based P2P file sharing tool. Core idea: file bytes never pass through the server. The server only does WebSocket signaling (Cloudflare Workers + Durable Objects), while the actual transfer happens peer-to-peer over a WebRTC DataChannel. It works for: - browser ↔ browser - browser ↔…

  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.

  Tt – P2P terminal sharing over WebRTCJan 2026 · ▲13

  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…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
