AC Bridge

AC Bridge turns the smart lights and plugs you already own into quiet status lights for Claude Code and OpenAI Codex. One glance at the room tells you whether your coding agent is working, waiting for your permission, waiting for input or done. No more watching the terminal, no ping sounds, no checking your phone.

AC Bridge is a desktop app for Windows, macOS and Linux. It listens to the hooks Claude Code and Codex already fire and shows each agent state as a colour or effect on your lights. It works with the agents you already run, so there is no model API key to add.

What you get:

• Up to 29 agent states, including working, needs permission, needs input, plan ready, context low and finished. You choose the colour for each one.
• One light per project, or one for several. Each repo gets its own profile, and Claude Code and Codex can run side by side.
• 16 brands on your local network: Philips Hue, LIFX, Govee, WiZ, Nanoleaf, Kasa, Tapo, Yeelight, WLED, Shelly, Tuya, Meross, SONOFF/eWeLink, Elgato, Roku and ESPHome. Plus the devices your Home Assistant already runs, and SmartThings through Samsung's cloud.
• Lights go back to how they were when a session ends.
• Your agent can use your devices too: ask Claude Code or Codex to flash the front room lights when a deploy is done. Locks, garage doors, valves and cameras are always refused.

Your prompts, code and session transcripts are never collected.

One plan: a 7-day free trial with no card needed, then £2.99 a month.
