Indie dev builds CoIsland, a notch-resident AI monitor with 37 connectors, entirely with Claude Code
DonTizi · reddit · 2026-09-28
Reddit user DonTizi released CoIsland, a macOS app living in the MacBook notch that schedules monitors across 35+ connectors (failed Vercel deploys, red GitHub Actions runs, Stripe payment failures, emails, Snowflake queries). When a monitor fires, you hand the alert to Claude Code, Codex, or Cortex Code, which works visibly in a card next to the notch — but never resolves the alert for you.
Key details:
- The Swift/SwiftUI app, 37 connectors, license server (Cloudflare Workers + Stripe + Keygen), and website were all written with Claude Code; the author planned, reviewed every diff, and tested
- The launch video was generated as an HTML page with a frame-by-frame timeline, rendered with Playwright and ffmpeg, music composed in Python; a project skill preserves design rules
- Where humans mattered: taste (music transitions took two iterations) and catching a 4K playback bug via Apple's hardware decoder
- Ships with Claude Code skills to auto-configure connectors and monitors
Free to try on Apple Silicon (macOS 14+); monitoring your own tools requires a one-time license at $19.99 early bird until Oct 25, then $59.99, no subscription, 30-day refund.
