## A browser with boundaries
Most browsers put every login, tab, and distraction into one long-lived container. Crest begins with **Spaces** instead. Give work, home, research, or a private session its own banner; Crest gives each one its own cookies, website data, history, archive, tabs, credentials, settings, and sync identity.
Switching Spaces changes more than the color of the window. It changes the browsing context.
## Two engines on Mac
Crest for Mac opens pages in **Chromium** by default. Its engine is built on
ungoogled-chromium,
with Google integrations removed, and runs Chrome Web Store extensions. Any
website or page can open in **WebKit** instead, which adds Reader, whole-page
translation, built-in content blocking, and FairPlay video. When a page needs
protected video, Crest switches to WebKit automatically, respecting any
unsaved-changes prompt before moving it. Choose the default engine and
per-website rules in **Settings → Engines**. iPhone and iPad use WebKit. The
engine guide lists what each engine
supports.
## Crest Studio and Appearance
**Crest Studio** puts each Space's crest on that Space's own sidebar background. Start from a template, then step through shape, field, band, emblem, border, finish and sidebar, choosing from previews of your own crest. Every part of the crest and the sidebar has its own color, named by what it paints. Use heraldic artwork, emoji, monograms, or a searchable SF Symbols picker, and Shuffle and Undo freely.
**Appearance** lets you dock the sidebar on either edge, go borderless, adjust tab shape and scale, choose a pin layout, and tune tab and address-field colors, or let them follow each Space's accent. Start with a preset, see changes live, and reset individual settings. Choose an app icon palette, folder colors and icons, and a default page zoom from 50% to 300%.
## Browsing features
- **A sidebar with structure.** Pins for everyday sites, saved tabs with a home URL, nested folders for projects, and current tabs for what you are doing now. Select tabs, Split Views, and folders together to organize them in one step.
- **Split View.** Keep two to four live pages in a group. Resize columns on Mac and iPad; move through focused cards on iPhone.
- **Peek.** Preview a link above the current page, then close it or keep it as a tab. On Mac, drag a link into a live Peek. On iPhone and iPad, native link and image menus keep touch actions close by.
- **Quick Window on Mac.** Open a link from another app using the right Space’s signed-in session. Promote it to a regular tab when it deserves to stay. Link Routing sends matching external links to their chosen Space.
