Yab vs Claude in Chrome

We make Yab, so read it as our side.facts checked Oct 9 ↓

Yab, Yet Another Browser, is a free Mac browser that keeps everything from Arc (tabs down the side, spaces, folders, Split View) and gives your Claude or ChatGPT plan an agent that works in your signed-in tabs.

Claude in Chrome is Anthropic’s Chrome extension that lets Claude read, click and type in your own signed-in Chrome, on a paid Claude plan. Claude Code can use it with claude --chrome.

The short answer

Pick Yabours

if you miss Arc and want spaces, pins and folders kept, on a Mac
if you already pay for Claude or ChatGPT and want it to work in your signed-in tabs
if you want Claude Code, Codex or Cursor to drive a real browser over MCP

Pick Claude in Chrome

if you pay for Claude and want it to work in the Chrome you already use
if you test web apps from Claude Code in a real, signed-in browser
if you want Claude to repeat browser chores on a schedule
