Playwright
Cross-browser automation by Microsoft
Cypress
Developer-focused E2E test runner
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.
Pick Playwright when you need multi-tab, multi-origin, WebKit, or large parallel test suites.
Pick Cypress when you want the smoothest developer UX and run a small-to-medium test suite.

cy.get('...') → page.locator('...'), cy.visit() → page.goto(), cy.intercept → page.route. Assertions move from Chai (.should) to Playwright's expect (similar to Jest). cy.task → test.step or custom fixtures. Most teams rewrite rather than migrate mechanically — plan 30-60min per test for rewrites.

Yes. Both have MCP servers installable via MCPizy (mcpizy install playwright and mcpizy install cypress). 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.
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.
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.
