Codex vs Playwright MCP
Codex, in the ChatGPT desktop app, has a browser of its own, computer use, and an extension that works in your signed-in Chrome, Edge, Brave, Opera or Vivaldi, on a ChatGPT plan.
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 code in the ChatGPT desktop app and want it to check your web app in its browser
- if you pay for ChatGPT and want tasks done in your signed-in Chrome
- if you want to leave comments right on the page you are building
- 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
- 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

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.

What their pages don’t lead with
Real limits, from the makers’ own words and our own use.
Codex
- In the desktop app only: not in Codex CLI or the IDE extension
- Computer use is limited by region and missing on Linux
- Its own browser uses a separate profile and can’t upload files for you
- No MCP server for other agents
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
