Dark Mode for the AppSignal UI

A dark theme for the AppSignal UI is here. Easier on the eyes for late deploys, and a good place to wrap Launch Week 2026.
Pick your Theme
Late deploys, on-call shifts, dashboards left open all day, the AppSignal UI spends a lot of time on your screen. Dark mode gives it a theme to match.
Click your profile icon in the top right, then set the Theme toggle to:
- Light: the default
- Dark: always-on dark mode
- System: follows your OS preference
The setting lives on your account, not your browser, so it follows you between devices. Every screen, from dashboards and incidents to the log stream and logbook, respects the theme you pick.
