Anyone running AI coding agents knows the routine: you kick off a task, walk away to grab coffee, and come back to find the agent has been sitting idle for 20 minutes waiting for you to click "Allow."
Greenlight is a new iOS app that solves this by forwarding agent permission requests to your phone as push notifications. You tap approve or deny right from the notification, and the agent keeps working. It supports Claude Code, Copilot CLI, Cursor CLI, and Codex CLI.
The timing is awkward. Anthropic recently shipped "Remote Control" for Claude Code, which covers similar ground for that specific agent. But Greenlight works across multiple coding agents, which gives it a niche for developers who bounce between tools.
The core problem is real. Permission prompts are the single biggest productivity drain with autonomous coding agents. The whole point of letting an agent run is that you can do something else while it works. Every blocked prompt breaks that promise. A phone-based approval flow is the obvious fix, and it's surprising the agent makers themselves haven't all built this natively yet.
Greenlight is available on the App Store now. For developers who primarily use Claude Code, Anthropic's built-in Remote Control may be sufficient. But if you're running multiple agents or want a unified approval queue, Greenlight fills a gap the big players haven't closed.
