v1.58.0

📣 Playwright CLI+SKILLs 📣

We are adding a new token-efficient CLI mode of operation to Playwright with the skills located at playwright-cli. This brings the long-awaited official SKILL-focused CLI mode to our story and makes it more coding agent-friendly.

It is the first snapshot with the essential command set (which is already larger than the original MCP!), but we expect it to grow rapidly. Unlike the token use, that one we expect to go down since snapshots are no longer forced into the LLM!

Timeline

If you're using merged reports, the HTML report Speedboard tab now shows the Timeline:

UI Mode and Trace Viewer Improvements

• New 'system' theme option follows your OS dark/light mode preference
• Search functionality (Cmd/Ctrl+F) is now available in code editors
• Network details panel has been reorganized for better usability
• JSON responses are now automatically formatted for readability

Thanks to @​cpAdm for contributing these improvements!

Miscellaneous

browserType.connectOverCDP() now accepts an isLocal option. When set to true, it tells Playwright that it runs on the same host as the CDP server, enabling file system optimizations.

Breaking Changes ⚠️

• Removed _react and _vue selectors. See locators guide for alternatives.
• Removed :light selector engine suffix. Use standard CSS selectors instead.
• Option devtools from browserType.launch() has been removed. Use args: ['--auto-open-devtools-for-tabs'] instead.
• Removed macOS 13 support for WebKit. We recommend to upgrade your macOS version, or keep using an older Playwright version.

Browser Versions

• Chromium 145.0.7632.6
• Mozilla Firefox 146.0.1
• WebKit 26.0

This version was also tested against the following stable channels:

• Google Chrome 144
