Best for

✓ Best for

Teams building complex web apps who need flexible and readable test scripts
Developers working with multiple frameworks and browsers needing a unified testing approach

✓ Best for

Developers who need to automate web page interactions for scraping, testing, or generating dynamic content.
Teams building headless browser automation tasks that require high-level API control over Chrome or Chromium.

Not ideal for

✕ Not for

Projects requiring real-time testing or continuous integration without setup overhead
Small projects where the overhead of setting up an additional testing framework is not justified

✕ Not for

Projects requiring real-time interaction with the browser as Puppeteer operates in a batch mode.
Applications needing lightweight solutions where running a full browser instance is not feasible.
