Developer Tools · Free · One-time PRO, free tier $69
Native Mac HTTP/HTTPS debugging proxy with a built-in MCP server, so AI coding assistants can read your captured traffic.
All apps
Quiet control for your MacBook notch: AI agent spend and approvals, timers, calendar, clipboard, files, media and stats.
Arrowslit turns the MacBook notch into a quiet control surface that appears only when something needs you:
- AI agents — live token spend, limits, cache efficiency and one-click approvals for Claude Code, Codex, OpenCode and GitHub Copilot.
- Focus — timer, Pomodoro, stopwatch and Keep Awake, with live readings in the closed notch.
- Your day — next calendar event, reminders, clipboard history and a scratchpad.
- Files and media — a file tray, now-playing controls, artwork and optional timed lyrics.
- System feedback — volume, brightness, charging, headphones, downloads and live CPU/memory stats in a compact two-wing strip.
Private by design. No account, no analytics, no ads, no telemetry. Clipboard history, notes and settings stay on your Mac. Agent usage comes from local logs; provider credentials stay with the provider.
Native and fast. Swift + AppKit, macOS 14 Sonoma or later, universal for Apple Silicon and Intel. Free and open source under GPL-3.0.
Install: brew trust j4yop/tap && brew install --cask j4yop/tap/arrowslit or download the latest DMG from GitHub.
