Most file sharing between devices on the same network still goes through the cloud. Upload somewhere, download somewhere else. Open Slack just to send a log to the person next to you.

Instbyte skips all of that. One command, a local URL appears, anyone on the same WiFi opens it in their browser — no install, no account, nothing leaves the network.

Stack: Node.js, Express, Socket.IO, SQLite. Frontend is vanilla JS. v1.9 has channels, drag and drop upload, passphrase auth, configurable retention, white-label support, read receipts, inline preview for images, video, PDF and code, and inline editing. v2.0 adds Docker and standalone binaries.
