What Is Selenium?

Selenium is probably going essentially the most well-established instrument within the area of automated browser testing (over 35,000 firms reported utilizing Selenium in 2025).

Initially launched in 2004, it has grown to turn out to be the de facto trade commonplace for practical testing of internet purposes. Whereas many of the present instruments for automated testing characterize one product, Selenium represents a set of instruments:

• Selenium WebDriver: The underlying API upon which builders write check scripts and speak to browsers.
• Selenium IDE: A record-and-playback instrument which may be utilized even by non-tech customers to construct easy check instances.
• Selenium Grid: A system for operating exams in parallel on quite a few machines, which is critical for intensive software program testing.

Within the background, Selenium is definitely applied on high of the WebDriver protocol. It interprets check instructions into JSON, sends them over HTTP to browser drivers, after which makes them execute inside the browser. This structure has labored properly for generations, although it does come at some efficiency expense.

What distinguishes Selenium is its protection. Selenium affords assist for almost all of the outstanding programming languages (Java, Python, C#, PHP, and JavaScript) and all the highest browsers (Chrome, Firefox, Safari, Edge, and even Web Explorer).

With 20 years of utilization, it additionally has an enormous neighborhood, intensive CI/CD pipeline integration, and an abundance of documentation and tutorials.

What Is Playwright?

Constructed by Microsoft and made obtainable in 2020, Playwright was created with trendy internet improvement in thoughts to resolve a variety of the problems testers have been going through when making use of Selenium for browser automation.

Architecturally, Playwright takes a distinct strategy. As an alternative of utilizing the WebDriver protocol and HTTP requests, it communicates with browsers by means of a long-lived WebSocket connection.

Playwright runs on the three most used browser engines — Chromium, Firefox, and WebKit — so it targets Chrome, Edge, and Safari. Playwright additionally boasts strong cell emulation and experimental assist for testing precise Android gadgets.

When it comes to programming languages, Playwright runs on JavaScript, TypeScript, Python, Java, and .NET, that are essentially the most used improvement stacks at the moment.

Playwright vs. Selenium: Key Function Comparability

Playwright reduces the problem with auto-waiting in-built. The check framework routinely waits for components to turn out to be obtainable earlier than dealing with them, which ends up in fewer false failures and extra steady check runs.

API Design and Developer Expertise

Selenium’s API is highly effective however can really feel verbose. Writing exams normally requires extra strains of code to deal with waits and synchronizations.

Playwright boasts a cleaner, trendy API. Clicking, hovering, or filling out types wants fewer strains of code. For builders who like to put in writing quick and expressive code, Playwright is a greater various.

Group and Ecosystem

Being available on the market for almost 20 years, Selenium has one of many largest check automation communities.

There is a gigantic library of tutorials, libraries, and integrations with CI/CD instruments. If you’re caught someplace, it’s seemingly that somebody has already discovered the right way to resolve it.

The Playwright neighborhood is smaller however rising very quick. Backed by Microsoft, it’s being actively contributed to, and trendy frameworks are more and more integrating with it.

Superior Options

Probably the most spectacular a part of Selenium is Selenium Grid, which permits distributed and parallel check execution on a number of machines. It’s extremely useful for giant groups and enterprise testing.

Playwright comes with a set of superior capabilities out of the field: screenshots, video seize, community interception, machine and geolocation simulation, and even timezone manipulation.

They arrive with no extra plugins, which is why Playwright is particularly well-suited for up to date, feature-rich internet purposes.

Check Runner & Framework Integration

Selenium doesn’t have a check runner in-built, however is appropriate with JUnit, TestNG, NUnit, and Pytest frameworks. That flexibility permits groups to pair it with no matter runner most closely fits their workflow.

Playwright has a built-in check runner, which affords an built-in strategy for individuals who like having every thing bundled collectively. It’s nonetheless appropriate with Jest, Mocha, Jasmine, and Pytest, nevertheless.
