Terminal
The fast, minimal foot terminal, ported natively to macOS with AppKit, CoreText and Core Animation. No Wayland, no X11, no emulation. An idle window sits at about 30 MB.
brew install --cask gobijan/tap/foot| foot | kitty | Ghostty | |
|---|---|---|---|
| Startup ms | 75 | 683 | 155 |
| Idle memory MiB | 31 | 86 | 62 |
| Idle CPU % | 0.04 | 0.29 | 0.65 |
| Idle wakeups per s | 0.3 | 2.3 | 16.2 |
Ghostty is still the fastest at raw output.
Unofficial port, not affiliated with upstream foot.
CSS
A small, composable CSS toolkit. Sharper defaults, finer colour steps, a CSS Grid layer and design tokens. One stylesheet, no build. This site runs on it.

Completes CSS class names in HTML from the stylesheets the page actually loads, jumps to their rules and warns about classes nothing defines. A single static binary with no configuration.

Bijan Rahnema has been shipping software on the web for more than twenty years. Day-to-day work revolves around Ruby on Rails and Go: running production systems at Screen Island, contributing to the Rails ecosystem, and publishing tools born out of daily needs.
Beyond our own repositories, we contribute patches, bug reports and documentation to the Ruby on Rails ecosystem and the broader open source community. Most of it never makes a headline, and that’s the point.
If you use these tools every day, you can sponsor the work on GitHub.
