BrowserStack
Real-device cloud for testing
Playwright
Cross-browser automation by Microsoft
Not truly competitors — BrowserStack is a real-device cloud (run your tests on 3000+ browser/OS combos including real iOS/Android), and Playwright is the test framework. Most teams use both: write tests in Playwright, run them on BrowserStack's grid for coverage they can't get locally.
Pick BrowserStack when you need real iOS Safari, legacy Edge, or hundreds of device/OS combos.
Pick Playwright alone when Chromium/Firefox/WebKit locally (or on CI) is enough.

This is usually an 'add', not a 'switch'. Keep your Playwright tests; point them at BrowserStack by setting wsEndpoint to the BrowserStack Grid URL and adding capabilities. Alternatively use @browserstack/playwright npm package. For cost control, run smoke locally on every PR, full cross-browser on BrowserStack nightly.

Yes. Both have MCP servers installable via MCPizy (mcpizy install browserstack and mcpizy install playwright). They work identically across Claude Code, Claude Desktop, Cursor, Windsurf, and any other MCP-compatible client. You can install both side by side and route queries in your agent's prompt.
Playwright (Microsoft) is the spiritual successor to Puppeteer — same core team, but cross-browser (Chromium, Firefox, WebKit), better auto-wait, built-in test runner, and first-class language bindings. Puppeteer remains solid for Chrome-only scraping/automation, but Playwright is the default for new projects.
Cypress pioneered modern E2E DX (time-travel debugger, docs, VS Code-feel). Playwright caught up and surpassed on: cross-browser, multi-tab, iframe handling, parallelization, and API testing. Cypress still has the nicer 'first 30 minutes' experience; Playwright wins at scale.
Selenium is the original cross-browser test framework — 20 years old, huge ecosystem, mandatory for legacy IE/old-Safari coverage. Playwright is modern, faster, has auto-wait, and doesn't need a separate driver. For new projects in 2026, Playwright wins on almost every axis except raw browser breadth.
