**Short answer.** Playwright is the default for new agent work: cross-browser, auto-waiting, one API in Python, Node, Java, and .NET, and a codegen tool. Puppeteer is fine for Chromium-only Node scripts. Selenium remains the choice when you need the WebDriver standard, a grid of real browsers, or languages the others lack.

## Comparison

| | Playwright | Puppeteer | Selenium |
| --- | --- | --- | --- |
| Browsers | Chromium, Firefox, WebKit | Chromium (Firefox experimental) | All, via drivers |
| Languages | JS/TS, Python, Java, .NET | JS/TS | Java, Python, C#, Ruby, JS, Kotlin |
| Auto-wait | Yes | Partial | No (explicit waits) |
| Network interception | Yes | Yes | Limited (BiDi improving) |
| Parallel contexts | Built in | Manual | Grid |
| Maintainer | Microsoft | Google | Selenium project |

## For agents specifically

- Prefer the site's API or a Markdown alternate before automating a browser.
- Use accessibility-tree snapshots rather than screenshots for element selection; they are cheaper and more reliable.
- Respect robots.txt and rate limits; a headless browser is still a bot.
