## Support for all browsers
|
||
|
|
* **Test on Chromium, Firefox and WebKit**. Playwright has full API coverage for all modern browsers, including Google Chrome and Microsoft Edge (with [Chromium](https://www.chromium.org/)), Apple Safari (with [WebKit](https://webkit.org/)) and Mozilla Firefox.
|
||
|
|
|
||
|
|
* **Cross-platform WebKit testing**. With Playwright, test how your app behaves in Apple Safari with WebKit builds for Windows, Linux and macOS. Test locally and on CI.
|
||
|
|
|
||
|
|
* **Test for mobile**. Use [device emulation](emulation.md) to test your responsive web apps in mobile web browsers.
|
||
|
|
|
||
|
|
* **Headless and headful**. Headless and headful automation is supported across all browsers and on all platforms.
|
||
|
|
|
||
|
|
## Fast and reliable execution
|
||
|
|
* **Auto-wait APIs**. Playwright interactions [auto-wait for elements](actionability.md) to be ready. This improves reliability and simplifies test authoring.
|
||
|
|
|
||
|
|
* **Timeout-free automation**. Playwright receives browser signals, like network requests, page navigations and page load events to eliminate the need for sleep timeouts that cause flakiness.
|
||
|
|
|
||
|
|
* **Lean parallelization with browser contexts**. Reuse a single browser instance for multiple parallelized, isolated execution environments with [browser contexts](core-concepts.md).
|
||
|
|
|
||
|
|
* **Resilient element selectors**. Playwright can rely on user-facing strings, like text content and accessibility labels to [select elements](selectors.md). These strings are more resilient than selectors tightly-coupled to the DOM structure.
|
||
|
|
|
||
|
|
## Powerful automation capabilities
|
||
|
|
* **Multiple domains, pages and frames**. Playwright is an out-of-process automation driver that is not limited by the scope of in-page JavaScript execution and can automate scenarios with [multiple pages](multi-pages.md).
|
||
|
|
|
||
|
|
* **Powerful network control**. Playwright introduces context-wide [network interception](network.md) to stub and mock network requests.
|
||
|
|
|
||
|
|
* **Modern web features**. Playwright supports web components through [shadow-piercing selectors](selectors.md), [geolocation, permissions](emulation.md), web workers and other modern web APIs.
|
||
|
|
|
||
|
|
* **Capabilities to cover all scenarios**. Support for [file downloads](network.md) and [uploads](input.md), native [input events](input.md), and even [dark mode](emulation.md).
|
||
|
|
|
||
|
|
## Integrates with your workflow
|
||
|
|
* **One-line installation**. Running `npm i playwright` auto-downloads browser dependencies for your team to be onboarded quickly.
|
||
|
|
|
||
|
|
* **TypeScript support**. Playwright ships with built-in types for auto-completion and other benefits.
|
||
|
|
|
||
|
|
* **Debugging tools**. Playwright integrates with the [editor debugger](debug.md) to
|
||
|
|
|
||
|
|
* **Language bindings**. Playwright is also available in [Python](https://github.com/microsoft/playwright-python) and [C#](https://github.com/hardkoded/playwright-sharp).
|
||
|
|
|
||
|
|
* **Deploy tests to CI**. First-party [Docker image](docker/README.md) and [GitHub Actions](https://github.com/microsoft/playwright-github-action) to deploy tests to [your preferred CI/CD provider](ci.md).
