Sideband

Local-first communication for browsers, daemons, and P2P apps.
No WebSocket plumbing. End-to-end encryption by default.

Cowork is a strong signal of where agentic workflows are heading.

I've been exploring similar ideas with Sideband — focusing on E2EE-first, trust-bounded workflows where files don’t have to leave the user’s control.

Introducing Cowork: Claude Code for the rest of your work.

Cowork lets you complete non-technical tasks much like how developers use Claude Code.

@luka_usdt @coinbureau Strong point! When centralized doors close, P2P rails matter. I'm building Sideband, a P2P-friendly protocol stack. If you see overlap, I'd love to learn and maybe collaborate.

Quick note on the name: "Sideband" comes from radio — carrying extra signals alongside the main carrier. That's the vibe I want for this stack: lightweight channels alongside your app, carrying control, RPC, and events without getting in the way. If it resonates, let me know 🙂

Shipped @sideband/protocol v0.0.5 🚢 Binary frames now carry timestamps, reserved bits enforced, and frame IDs stay pure entropy. TypeScript/Bun friendly. GitHub: https://t.co/DKxlXZegpU #realtime
