I kept starting long agent runs, leaving the laptop, and finding out an hour later they'd stalled two minutes in on a permission prompt, or asking me a question. Cosyncing is a self-hosted server that watches the coding agents already running on your machine and serves clients to your phone, desktop, and browser. Permission requests, agent questions, and finished runs all land in one inbox — answer from whatever device you're holding. Prompt from the app while the terminal keeps running; neither side drifts. Works with Codex, OpenCode, Pi, Kimi Code, and DeepSeek Harness for full two-way sync; Claude Code is read-only until you take over. Runs over your own Tailscale network — no relay of mine in the path, no telemetry. Apache-2.0, free. ▎ npm install --global cosyncing → cosyncing setup → cosy pair. What should I support next?
