🛠 Buzz: CLI Agent Notifications on iPhone

BuzzKit released the open-source iOS app Buzz: Claude Code, Codex, and Cursor send notifications to an iPhone with a single POST to ping.buzzkit.dev/YOUR_KEY. Task completion arrives as a push notification, a Live Activity with a progress bar appears on the lock screen and in the Dynamic Island, and status:"waiting" brings up a 'Waiting on you' card when the agent needs approval.

🌍 Instead of custom webhooks, it uses the pattern of 'one POST endpoint + skill.md + remote MCP': the open-source framework manages APNs keys itself and aggregates dozens of parallel agents into a single Live Activity with one push token. The barrier to entry is lower than even for CI and shell scripts.

👤 Install the TestFlight beta and step away from the terminal: your phone will notify you of completion, errors, or approval requests, and progress will be shown on the lock screen. Setup takes a minute: a six-digit code and skill.md for the agent. You can self-host it.
