Why Seek a Selenium Alternative
Selenium became the go-to framework for browser automation tasks like testing and web scraping among developers for its flexibility and extensive language support. But the disadvantages we'll see next compel the need for other options.
Selenium Isn't So Fast
Speed is crucial for both testing and web scraping. And although Selenium is versatile, its WebDriver scripts could be faster, and a reason for this is they run through the browser. Browsers can be slow, particularly due to loading additional resources, like stylesheets, scripts, extensions, etc.
You may speed up your scripts to some extent by blocking unnecessary resources, but automating a browser with Selenium often requires timing checks, synchronization, and waiting, which can increase project time.
In a nutshell, Selenium is slow, and slow test suites may affect the overall CI/CD pipeline, disrupting release and deployment. Similarly, delayed scraper execution can be frustrating. Meanwhile, the speed is better with more modern tools that e.g. use the Chrome DevTools protocol to automate Chrome.
Not Cost-effective When Scaling Up
While Selenium itself is open-source and free to use, its scalability can bring about costs that are less apparent initially. Large-scale projects with Selenium often require running and maintaining multiple instances. Selenium runs these instances in a particular order with limited resources, contributing to the lack of speed discussed earlier.
A better approach would be running in parallel. However, managing and maintaining multiple Selenium instances in parallel requires high-end infrastructure and powerful machines to handle the load efficiently. This can lead to increased costs beyond just the machine provisioning fees but also data transfer, storage, and any additional services you use for scalability.

You Get Easily Blocked While Web Scraping
When web scraping, the goal is to fly under the radar to retrieve the necessary data. But Selenium, like most headless browsers, exhibits automation properties that make your traffic too easy to get flagged as coming from a bot and, therefore, be denied access.
Configurations and tools like Undetected Chromedriver exist to avoid bot detection in Selenium, but advanced anti-bot systems can still block you.
1. Playwright: Microsoft's Cross-browser API
Developed by Microsoft, Playwright is quickly gaining popularity, and its impressive growth speaks volumes about its capabilities. With over 55k stars and 3k forks on GitHub, it's clear that this browser automation tool has struck a chord with the developer community.
Playwright is a Selenium open-source alternative that provides a single API for automating Chromium, WebKit, and Firefox. It generally offers better performance and speed than Selenium due to its intuitive API and auto-waiting functionality.

"The display for e2e tests at every step is really what I always hoped for in an e2e testing software." — Ian Wyatt.
5. Cucumber: The Behavior-Driven Development Solution
Cucumber is an automation framework for Behavior-Driven Development (BDD) testing, which is an approach that enables the tester to write test cases in human-readable text (English), known as Gherkin. This allows developers, managers, and stakeholders to collaboratively define and understand the expected behavior of software features. That defined behavior (in plain text) results in test execution as Cucumber translates it into automated tests.
- 🔝 Uses human readable language
- 🔝 Easy to use.
- Reusable code.
