Cypress vs Playwright: Major Differences in Speed and Performance
When people ask which tool is faster, they often mean different things. For some, speed is about how fast a single test runs. For others, it is about how many tests finish in a short time. Speed can also mean how quickly developers get feedback during coding. Each of these areas matters in real projects.
The comparison table below highlights Cypress vs Playwright based on 17 practical factors. These include startup time, execution speed, debugging, and cloud testing compatibility. Each point is based on actual project use, not just tool documentation.
