If you need web navigation that handles JavaScript-heavy pages and login flows reliably, the best fit is usually Playwright.
Why Playwright
- Runs real browser engines: Chromium, Firefox, and WebKit
- Handles dynamic, JS-heavy sites well
- Good for login flows: form filling, redirects, OAuth popups, cookies/session handling
- More reliable than simple HTTP-based tools for modern web apps
Also worth considering
- Selenium: widely supported, good for browser automation, but often a bit more brittle/slower than Playwright.
- Puppeteer: strong for Chromium-based automation, but less cross-browser than Playwright.
Short recommendation
- Best overall: Playwright
- If you need legacy support / widest ecosystem: Selenium
- If you only need Chromium: Puppeteer
If you want, I can also recommend the best tool depending on your exact use case, like scraping, QA testing, or authenticated browsing.
