Nowadays, every organization wants an all-in-one automation testing tool that can perform several types of testing such as frontend web UI’s, backend APIs, etc. Also, we must be able to extend that tool/framework further as per the needs i.e. it should support various third-party integrations. So, In the current competitive market situation finding such a perfect tool becomes a critical task for any organization. A complete comparative analysis of existing modern automation tools- Selenium vs WebDriverIO vs Cypress vs Playwright vs Nightwatch is provided in this blog.  

This blog covers most of the important key features of mentioned automation tools, with a complete in-depth comparative analysis. Finally, this blog will undoubtedly assist you in selecting the ideal automation solution that can meet the majority of the project’s requirements. 


Selenium WebDriver is by far the most popular framework with large community support. It uses a JSON wire protocol to communicate between the Selenium script and the browser drivers like Chromedriver, geckodriver, etc. It is widely used with Java but it can also be used with Python, Javascript, Ruby, c#, etc. Whereas  WebDriver IO is a custom implementation of Selenium WebDriver which overcomes some of the Selenium limitations, for example, It has default implicitly wait for an element, etc. Nightwatch is a Node.js application. It uses the W3C WebDriver API to drive browsers like Selenium or WebDriver IO to perform commands or assertions on DOM elements.

Automation tools like Selenium work by running outside the browser. The Cypress, on the other hand, utilizes a different architecture and is browser-based. Cypress is based on the proxy server – Node.js. Microsoft has developed Playwright, a Node.js tool for automating browsers. The playwright is a more powerful version of Google’s Puppeteer, which isn’t compatible with Safari or Firefox.

Licensing or Pricing

Selenium WebDriver, WebDriver IO, NightWatch, Cypress, and Playwright are Open-Source and free to use. However, Cypress provides advanced features in its paid version which includes Cypress Dashboard, DOM snapshots, video storage, etc which are useful for debugging.

Modern Development Frameworks Support  

However, using Selenium WebDriver, WebDriver IO, Night Watch, Cypress, or Playwright, one can automate any modern web application. E2E tests must validate all the application’s layers. This includes not only frontend UI but also all associated backend services and infrastructure that is more representative of the environment that users will be in. 

E2E tests are typically the key to higher confidence in whether an application is functioning properly or not by testing how user activities affect the application. Hence, one must choose the right automation testing tool. Cypress, Playwright, and NightWatch are best for testing React, Angular, or Vue.js applications, as they provide some extra features. 

Testing Scope – Web/Mobile App/APIs 

Selenium is used for the automation of Web UI only, but one can extend the framework with the help of third-party tools such as Rest APIs to automate API services and Appium tool to automate Android Applications. WebDriver IO, Cypress, and Playwright can all be used to automate Web UI and API services. 

Also, with the help of WebDriver IO and Playwright, one can easily automate mobile web applications also. NightWatch, on the other hand, can only be used for web UI automation because it currently lacks an out-of-the-box solution for API testing. 

Testing scope

Testing Framework Support 

Most of these tools are used for automation, however, a testing framework is required to perform assertions and grade a test as pass/fail/skip. For example, Selenium with Java, TestNG framework is most widely used. The following is the comparison chart.

Flaky Resistance – Retry Test 

Sometimes a test fails because of some external issues like internet connectivity issues, page timeout, UI not loaded properly, etc. And not because of any bug. So we must give such tests another try and execute them. If any such test passes in its next attempt then it is called a flaky test. So having such retry test capability in automation tools is especially important.
