Show HN: Crest – Answer Claude Code approvals from your MacBook's notch (crestnotch.app)

Crest, a new app for MacBook users, enhances workflow efficiency by utilizing the device's notch to manage Claude Code and OpenAI's Codex permission prompts. When permissions are needed—such as allowing a Bash command to run—Crest displays an unmistakable notification in the notch, allowing users to tap "Allow" or "Deny" without interrupting their tasks. This ensures that even if users are focused on other applications or fullscreen modes, they receive timely prompts to keep their coding sessions from becoming idle. The app's integration with Claude Code's built-in hooking system means it operates seamlessly without interfering with normal terminal behavior. This development is significant for the AI/ML community as it addresses a common frustration experienced by developers: waiting for prompts while running code. By placing permission requests directly in a prominent and persistent location on the screen, Crest minimizes idle time and streamlines the coding process. Additionally, with features that allow detailed views of the commands being requested and an option to reply directly from the terminal, Crest promises to enhance productivity. Users can easily set it up with no API key requirement, making it accessible for those looking to boost their coding efficiency with AI tools.
