There are a number of options when for frameworks for end-to-end testing. If you’re thinking about using Checkly, you’re likely aware of a few.

Puppeteer vs Playwright

The resemblance to Google’s Puppeteer is striking, and for good reason. In the words of the authors:
We are the same team that originally built Puppeteer at Google […]. With Playwright, we’d like to take it one step further and offer the same functionality for all the popular rendering engines. We’d like to see Playwright vendor-neutral and shared governed.
In short, Playwright builds on the experience of Puppeteer to provide a way to:
  1. run against all major browsers (Chromium/Chrome, Firefox, WebKit/Safari)
  2. write more concise scripts (e.g. minimising the need for explicit waits)
  3. easily migrate existing codebases (keeping a very similar API)
This is achieved in the form of a compact node library that exposes a high-level API to interact with web pages in a fast, secure, stable and simple way. As it is an open-source project, you can contribute to it yourself.

Playwright vs Cypress

Long the dominant framework for (at the time) modern end-to-end testing, Cypress is still very widely used as a testing framework by front-end focused teams. Due to architectural differences, Playwright can support multiple languages for writing tests, and run more browsers for testing. Due to Playwright’s status as a free and open source project, users don’t have to deal with new features being paywalled, a significant issue for Cypress users since 2023.
