Playwright
The browser-automation standard: script Chromium, Firefox, and WebKit.
About
Playwright is Microsoft's end-to-end testing and browser-automation framework: script real Chromium, Firefox, and WebKit with auto-waiting selectors, network interception, tracing, and screenshots — in Python, Node, Java, or .NET. It's the engine under most serious web-scraping and agent browser stacks (browser-use, Stagehand build on it). 97.6k stars, Apache-2.0, 462M npm downloads/month. The API is stable and the docs are excellent; just don't reach for a full browser when a plain HTTP client would do.
What it can do
- **Cross-browser**: Chromium, Firefox, WebKit with one API
- **Auto-waiting**: actions wait for elements — no flaky sleeps
- **Network control**: intercept, mock, and record traffic
- **Tracing & screenshots**: first-class debugging artifacts
- **Parallel contexts**: isolated browser contexts per test/task
- **Agent foundation**: powers browser-use, Stagehand, and most web agents
Setup
```bash
pip install playwright && playwright install chromium
```
```python
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch()
page = browser.new_page()
page.goto("https://example.com")
print(page.title())
browser.close()
```
Docs: playwright.dev.
Prerequisites
Python 3.9+ or Node 18+. Browsers downloaded via `playwright install`.
