ArrowslitVerified on MacBase

Arrowslit is a free, open-source Mac app that puts a control panel in the MacBook notch. Hover the top edge of the screen or click the menu bar icon, and it opens; move away and it closes. It is for people who keep timers, music, calendar, clipboard and system stats in separate menu bar apps, and for developers who run coding agents and want to see usage and approve commands without switching windows. It works on MacBooks with a notch, on external displays and on Macs without a notch by drawing a virtual notch at the top centre. The panel combines a focus timer, Pomodoro and stopwatch with now playing, calendar, reminders, clipboard history, a file tray with AirDrop and a local scratchpad. It reads token and plan usage for Claude, Codex, OpenCode and GitHub Copilot, and shows approval requests from Claude Code, Codex, Copilot CLI, Antigravity, Cursor and OpenCode with Allow, Deny and Ask in CLI. It also shows CPU, memory, disk, network and live football scores, includes a camera mirror and keep awake, and opens every tool from a launcher grid. The difference is the combination: one free panel for the daily tools and the agent tools, instead of a separate app for each, and it works on Macs without a notch. Arrowslit is native Swift and AppKit. It has no account, no analytics and no telemetry. Clipboard history stays in RAM; only pinned clips are written to disk, and password-manager items are skipped. Calendar, Reminders and Camera permissions are requested only when those tools are opened. Lyrics lookup and live sports are optional network features; lyrics are off by default, and live sports use your own data key. It is free software under GPL-3.0, for macOS 14 or later, universal on Apple silicon and Intel.
