Lisse by Jace

Gives every website the smooth corners you see on iOS. Same radius the site chose, just a nicer curve. Capsules included.

Lisse softens website corners to look more like iPhone curves. Instead of a sharp turn, it uses Apple’s gradual easing, while keeping the original radius unchanged. Nothing moves or resizes, so buttons and menus stay in place, and pill-shaped controls get the same smooth treatment.

It redraws borders and restores shadows when needed, but leaves anything it can’t handle cleanly as is. Lisse begins before the page finishes loading, updates elements as they appear, and reapplies changes after hover or focus animations.

You can toggle it per site from the toolbar icon: green on, red off. It’s on by default, remembers disabled sites, and doesn’t run on blocked pages. Everything stays on your computer. It only saves the sites you’ve turned off.
