Super Claude browser extension makes Claude.ai UI fully customizable
A developer who spends 8+ hours daily on Claude.ai has released a browser extension called Super Claude that makes the entire interface customizable. The extension addresses the "bland" default white interface by providing granular style control beyond just dark mode.
Key customization features
The extension enables complete visual customization of Claude.ai:
- Color selection for all interface elements
- Font changes
- Layout adjustments
- Usage tracking functionality
- Token counting
According to the developer, users have created diverse visual themes including:
- Full terminal aesthetics
- Softer backgrounds for late-night use
- Cyberpunk-inspired interfaces
The developer notes that while the extension includes usage tracking and token counting features, users primarily engage with the styling capabilities, frequently sharing screenshots of their customized interfaces.
Technical implementation
The extension was built solo using Claude itself, which assisted with:
- CSS injection system
- DOM manipulation for live preview functionality
- Service worker architecture
Availability
Super Claude is available for both major browsers:
- Firefox: https://addons.mozilla.org/firefox/addon/super-claude/
- Chrome: https://chromewebstore.google.com/detail/super-claude/hogiifbepjnfjaikjfifaacppefnjblg (note: Chrome version was still under approval at time of posting)
The extension is free and provides a practical solution for developers who spend extended periods in Claude.ai and want to personalize their workspace.
