Blocks · Browser

The page beside the terminal that serves it.

A browser as a block. Its localhost is the session's host, so the dev server running in the shell beside it shows right there, local or remote.

A drawing, not a recording. The Browser block runs only in the desktop app, and the recordings on this site are made in the browser workbench.

What it does.

The host's localhost: Loopback and private addresses open through the host the session runs on.
A block like the others: Pin it, split beside it, maximize it. Its toolbar is its header.
Where agents show their work: Claude Code opens the page it is building here.
Chromium on Linux and the Mac: One engine contract, so other engines can follow.

The desktop app comes with a local host. Add a remote one when you need it.
