Dark mode for the dashboard has come up a few times (2023: Dark Mode for fly.io website dashboard , 2025: Fly.io Dashboard Dark Mode ), so I made one.
It covers apps, Machines, Postgres, fly.toml, billing and sign-in, and keeps Fly’s violet. It’s generated from the dashboard’s own CSS, so hover/focus states and layouts behave like the original.
Install with Stylus: GitHub - rojnwa/fly-io-dark-mode: 🌙 Dark mode for the Fly.io dashboard: a smooth, purple-tinted Stylus userstyle (UserCSS) for apps, Machines, Postgres, billing and sign-in. One-click install, auto-updates. · GitHub
