SideCli is a lightweight native terminal for macOS built to stay out of your way. 100% free to use.
Its main feature is edge-snapping: move your mouse to the screen edge and the terminal instantly slides out; move away and it hides again. No hotkeys, no window juggling, no clutter.
Supports multi-monitor setups, pin mode, tabs, split panes, dark/light themes, and more — all in a ~3MB open-source app built with xterm.js.
