What do people build with it?

USE CASE 1

Write cross-browser end-to-end tests for your web app that auto-wait for elements and run in parallel across Chromium, Firefox, and WebKit.

USE CASE 2

Automate browser tasks like taking screenshots or generating PDFs with a simple script using the Playwright Library.

USE CASE 3

Connect an AI assistant to a live browser via the Playwright MCP server so it can navigate pages and click elements.

USE CASE 4

Debug failing tests by replaying recorded traces in the Playwright Trace Viewer.

In plain English

Playwright is a framework for automating web browsers and testing websites. The idea is that you write code that drives a real browser, opening pages, clicking buttons, filling out forms, capturing screenshots, and the same code works against three different browser engines through one API: Chromium, Firefox, and WebKit. The README says it can be used in tests, in scripts, and as a tool for AI agents. It ships as several entry points that share the same engine. Playwright Test is a full test runner built for end-to-end testing, with features the README highlights such as auto-waiting (so commands wait for an element to actually be ready instead of relying on artificial timeouts), web-first assertions that retry until conditions are met, isolated browser contexts for each test (equivalent to a fresh browser profile), tracing that records the run for later inspection in a Trace Viewer, and parallel execution across configured browsers by default. The Playwright Library is the same browser control without the runner, useful for one-off scripts that visit a page and take a screenshot or generate a PDF. There is also a Playwright CLI for coding agents, a Playwright MCP server that lets AI assistants control a browser through the Model Context Protocol, and a VS Code extension for authoring and debugging tests. You would reach for Playwright if you want cross-browser end-to-end tests for a web application, programmatic browser automation, or a way to let an AI agent drive a browser. It is written in TypeScript and installed via npm.

Copy-paste prompts

Prompt 1
Using Playwright Test, write a test that opens my login page, fills in the email and password fields, clicks submit, and asserts the dashboard URL appears.
Prompt 2
Write a Playwright script that opens a product page, takes a full-page screenshot, and saves it as a PNG file.
Prompt 3
Set up Playwright to run end-to-end tests in Chromium, Firefox, and WebKit in parallel and output an HTML test report.
Prompt 4
Use the Playwright MCP server to let an AI agent open a browser, navigate to a URL, and click a specific button on the page.
Prompt 5
Configure Playwright Test with isolated browser contexts per test and enable tracing so I can inspect failures in the Trace Viewer.
