These are a few differences between the Puppeteer and cypress
Puppeteer is Open source but Cypress is Paid( bit of open source)
Cypress is a Javascript End to End testing framework, Puppeteer is not a framework but the chromium version of node modules.
Puppeteer is great for quick testing and web scraping. But when it comes to testing an entire application it’s better to stand on the shoulders of the giants.
Cypress contains its own assertions but we might need to depend on Jest or Jasmine or Mocha when we are using the puppeteer.
Cypress has its own IDE, Puppeteer does not have one and most of the industry uses VSCode or Webstrom with the puppeteer.
Cypress supports multiple browsers but Puppeteer supports only chromium engine-based downloads.
Cypress has its own dashboard but puppeteer does not have any.
Puppeteer is much faster than Cypress
Cypress automatically waits for commands and assertions before moving on. No more async hell. Puppeteer has promises and async headache (handled using sync and await).
Cypress is more user-friendly compared with the puppeteer.
