A dark theme for the AppSignal UI is now available as part of AppSignal Labs.
Light mode remains the default. To opt in, click your profile picture in the top-right corner and switch the Theme toggle to:
- Light — the default
- Dark — always-on dark mode
- System — follows your OS preference
We're rolling this out gradually as we polish the rough edges, so expect a few screens that aren't quite there yet. Found one that doesn't look right? Tell us — that's the whole point of Labs.
