I build small tools.
These are two utilities I made and maintain. Both are free and open source, in case they're useful to you too.
Apps
macOS · menu bar
Scan Screen QR Code
Reads QR codes that are already on your Mac's screen, so you don't have to point a phone at your monitor.
- Scans the whole screen or a region you select, from the menu bar icon or a global hotkey.
- Handles QR, Aztec, DataMatrix, and PDF417. Decoded text is copied to your clipboard, and links can open in your browser.
- Detection happens on-device with Apple's Vision framework; nothing is uploaded or saved.
terminal · tmux
tend
Shows what the AI coding agents in your tmux session are doing.
- Detects agents like Claude Code and Codex in your panes and reports whether each one is blocked, working, or idle.
- The dashboard also shows the git branch and repo state for each pane, and can switch you to a pane directly.
- Has no runtime dependencies. JSON output is available for scripts and tmux status bars.
