YabYab vs Playwright MCP
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.
Playwright MCP is Microsoft’s free, open-source MCP server that lets an agent drive Chrome, Edge, Firefox or WebKit through Playwright, in a profile of its own by default.
The short answer
- 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
- if you run agents in CI and tests that need a clean, repeatable browser
- if you want it in any MCP client: Claude Code, Codex, Cursor or VS Code
- if you check pages in Chromium, Firefox and WebKit

Where they differ
What separates them, area by area. Where one plainly has more, it says who; where it comes down to taste, it says so.
What it drivesa matter of taste
Yab’s agent works in tabs of its own beside yours, signed in as you, on your Claude or ChatGPT plan; Send, Pay and Delete wait for your yes. Playwright MCP has no model of its own: your agent drives Chrome, Edge, Firefox or WebKit, reading pages as accessibility snapshots, in a profile of its own, a clean one, or your Chrome through extension mode.
Your sign-insa matter of taste

Where Playwright MCP is better
Playwright MCP comes out ahead on where it runs. It is also the better pick if you:
- Run agents in CI and tests that need a clean, repeatable browser
- Want it in any MCP client: Claude Code, Codex, Cursor or VS Code
- Check pages in Chromium, Firefox and WebKit
The catch with each
Real limits, from the makers’ own words and our own use.
Playwright MCP
- Its own profile has none of your sign-ins unless you use extension mode
- Extension mode works only in Chrome and Edge
- Brings no model: needs an MCP client and Node.js
- Microsoft suggests its command line for coding agents, since MCP uses more tokens
Yab, honestly
- Mac only: macOS 15.4 or later, no Windows, iPhone or Android
- New: first released in September 2026
- Its AI needs a Claude or ChatGPT plan; ChatGPT’s free plan may work with low limits
- WebKit, as in Safari: a site tested only in Chrome can misbehave
- Closed source
