Not sure whether to go with Selenium, Puppeteer, or Playwright? 🤔 Don't worry! Choosing the right one will be easier with this guide.

What are automation frameworks?

Automation frameworks are the backbone of any scripted browser workflow, as they automate web actions: 

• Running repetitive tasks 
• Testing UI behavior
• Creating multiple accounts
• Scraping structured data

Selecting a good framework saves you time, increases reliability, and keeps things scalable. In the context of Multilogin, they become even more critical, as you are automatic isolated browser profiles while handling anti-detection. Your chosen framework needs to be robust enough to support real-world complexity, not just run a local script once.

Best scenarios for each tool

Selenium

• Working in an enterprise environment with legacy systems
• Needing broad language support or must test on Safari
• Implementing tightly integrated WebDriver tools

Puppeteer

• Working Chrome-only, prioritizing speed
• Creating automation scripts, scrapers, or headless tools
• Implementing a low setup overhead with minimal dependencies

Playwright

• Needing multi-browser testing, including WebKit (i.e., Safari)
• Requiring modern automation with CI/CD compatibility
• Looking for smart features: auto-waiting, built-in parallelism, and advanced selectors

Comparing frameworks

Why is Selenium the standard?

Selenium is the most battle-tested name in browser automation: compatible with a wide range of languages and browsers, it is still the default choice for serious, scalable automation. Check its highlights:

• Cross-browser coverage: Chrome, Firefox, Safari, Edge – it runs everywhere!
• Language flexibility: compatible with Java, Python, C#, JavaScript, Ruby
• Ecosystem maturity: supports CI/CD, reporting tools, third-party plugins, etc
• Enterprise trust: delivers stability and test coverage even in most scenarios

Need an example script?

Below you will find pages containing fully-functional example scripts. They already include login/start/stop profile endpoints to be used as a base code.

• Selenium automation example
• Puppeteer automation example
• Playwright automation example

Your first choice doesn’t have to be forever. Try one, run a test, and switch if it doesn’t click.

The best tool is the one that works for your workflow.
