Sill / Make it yours

A browser that fits.
As you move.

Drag the chrome-size slider and watch your browser make room. Find a setting in seconds, then make Sill feel like your workspace.

Your size. In real time.

Move from roomy 88-pixel chrome to a 36-pixel compact frame. The balanced default is 72 pixels. The preview follows your slider movement; releasing it saves your size.

One row. More room.

As top chrome gets smaller, the workspace, tabs, navigation, address and menu consolidate into a single row. Autofill, Inspect, bookmarks, protection and downloads remain accessible in the labeled More menu and through keyboard shortcuts.

Find it. Change it.

Search across settings, then open the matching category and control. Appearance, saved data, browsing history, protection, developer tools and updates have clear places in the sidebar.

Works with Glide.

Pinned top Glide reserves exactly the height you choose. Unpinned Glide stays over the page. Side Glide uses grouped controls, a scrolling tab list and a live width slider. Resizing the chrome keeps your page text and settings text at their normal sizes.

Still your browser.

Twenty color palettes, eight illustrated skins and custom colors stay within reach. Add transparent PNG artwork over your chosen color, or use a clean surface.

New in beta24

A proper home for your tabs.

Left and right Glide now use a structured workspace panel. Navigation and the address sit together, tabs scroll in their own space, and labeled tools stay within reach at the bottom. Your workspace and window controls have clear places at the top.

Drag Panel size directly in the side panel to move smoothly between 336 and 248 pixels wide. The balanced width is 310 pixels. Pinning reserves the chosen width; unpinning gives the page the whole window.
