Playwright vs Puppeteer: Which MCP should you use?
Playwright
Cross-browser automation by Microsoft
Puppeteer
Chrome/Chromium automation library
TL;DR
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.
Pick Playwright
Pick Playwright when you need cross-browser coverage, modern test runner, or parallel test sharding.
Pick Puppeteer
Pick Puppeteer when you only target Chrome and already have a scraping/automation codebase.

Migration path
APIs are 80% similar. Swap page.waitForSelector → page.locator().click() (auto-waits), page.evaluate → page.evaluate (same), launch flags → use { channel: 'chrome' } or explicit browser. Tests: replace Jest + Puppeteer with @playwright/test. Use playwright codegen to regenerate selectors. Budget ~1 day per hundred tests.
Frequently asked questions
What is the main difference between Playwright and Puppeteer?
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. In short: Playwright — Cross-browser automation by Microsoft. Puppeteer — Chrome/Chromium automation library.
When should I pick Playwright over Puppeteer?
Pick Playwright when you need cross-browser coverage, modern test runner, or parallel test sharding.
When should I pick Puppeteer over Playwright?
Pick Puppeteer when you only target Chrome and already have a scraping/automation codebase.
Can I migrate from one to the other?
APIs are 80% similar. Swap page.waitForSelector → page.locator().click() (auto-waits), page.evaluate → page.evaluate (same), launch flags → use { channel: 'chrome' } or explicit browser. Tests: replace Jest + Puppeteer with @playwright/test. Use playwright codegen to regenerate selectors. Budget ~1 day per hundred tests.
Do Playwright and Puppeteer both work with MCP-compatible AI agents?
Yes. Both have MCP servers installable via MCPizy (mcpizy install playwright and mcpizy install puppeteer). 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.
More Testing & Browser comparisons
Playwright vs Cypress
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.
Playwright vs Selenium
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.
BrowserStack vs Playwright
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.
