What Stylus does
Stylus injects custom CSS into pages you visit, changing how they look without touching the underlying site. You can install styles other users have shared, or write your own from a built-in editor, then toggle each style on or off per site.
Stylus free vs paid
Stylus is free to use, covering custom CSS injection, the built-in editor, and installing shared user styles. There's no separate paid tier for additional features.
Is Stylus safe?
Stylus needs to read and modify the pages you visit to apply CSS, which is required for any styling extension. Custom CSS itself can't run scripts or access data beyond appearance, but styles shared by other users should come from repositories you trust.
