Butterfly Drop

Instant P2P file sharing — private, fast, and serverless

What it does

Butterfly Drop uses WebRTC DataChannels for true device-to-device file transfer. The server only handles signaling (SDP/ICE) and never touches file data. Sessions are ephemeral, encrypted, and require no accounts or installs — resulting in LAN-speed transfers with minimal overhead and a tiny frontend bundle.

    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.

    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…

    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
