Browser panes

A browser pane is a real Chromium, rendered off-screen and composited on the same GPU surface as your terminals: Metal and IOSurface on macOS, wgpu on Linux, D3D11 on Windows. It splits, zooms, focuses, and targets like any other pane:

zz new-browser https://crates.io
zz split-browser -h                  # split the current pane
zz set-browser-url -t %3 https://docs.rs

URLs typed in the address bar are http(s) only; localhost and loopback addresses default to http. Clicking a URL in a terminal pane opens it in the nearest browser pane of the same window. The OS browser is only used when the window has none.

Profiles

Every pane runs a named, persistent, zz-owned profile. Cookies, cache, and storage are shared between panes with the same profile name and isolated across names. zz never touches your Chrome profile.

Chrome import

Import Chrome data (macOS and Linux) decrypts a read-only snapshot of a Chrome profile’s cookie and history databases, via the system keychain, and injects cookies into the pane’s zz profile. Chrome’s files are never written. History fills the “Recently visited” list on blank pages. Passwords and autofill are never imported.

You can also import a Cookie-Editor JSON or Netscape cookies.txt file.

Element picker

Click the inspector icon, then click any element on the page. You get an inspector-style source context, including the React source file and line when the page exposes it, plus a screenshot of that element, together in one clipboard entry, ready to paste wherever you need it.

Chromium’s own DevTools are one keystroke away (cmd-alt-i / ctrl-shift-i, or right-click → Inspect element).

Limits

No find-in-page yet. Downloads, file dialogs, and permission prompts are denied; popups open a new tab in the same pane instead of a window.
