We compared Puppeteer, Playwright, and WebDriverIO in a benchmark to determine which is faster for synthetic monitoring and testing. The results showed that Puppeteer was significantly faster on shorter scripts, with an average execution time of around 30% less than Playwright. However, the difference in execution time between Playwright and Puppeteer vanished when running against a real-world web application. In contrast, WebDriverIO showed lower variability in its performance compared to Selenium. The benchmark highlighted the importance of considering the scope and differences between tools before evaluating their speed.
