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.

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: github.com/sidebandtech/side… #realtime
