Let’s explain to you What is Playwright and what is it for? this free open source tool. With it you can make a web browser work on its own without anyone touching it, and it’s something you’ve probably heard about in the context of artificial intelligence and the AI agents.
This is an increasingly present element in the world of AI, and it is worth knowing about it. Therefore, even if you don’t have technical knowledge, we are going to try to explain it to you in a simple way.
What is Playwright
Playwright is an open source tool created by Microsoft. It is an automation program that allows you control a web browser using code, so that it does things on its own, such as opening pages, clicking buttons or filling out forms.
The beauty of this program is that it does not control its own browser or anything like that, but you can use it in the browsers on your computer. It is compatible with Chromium, Firefox and WebKitbrowser engines such as Chrome, Edge, Firefox or Safari. Come on, you can use it on them to automate tasks.
This is a completely free and open source project that Microsoft maintains on GitHub with the Apache 2.0 license, and an active community. You can access the project with its official website playwright.dev and its repository at github.com/microsoft/playwright.
What is Playwright for?
The use for which this tool was created is perform automatic tests on web pages. For example, if a company develops a website or app, they can have Playwright do things on it to check that everything works, and also when making changes to some elements. Thus, they can try from the purchase button to the registration button.
You can also test web applications or web games, and check how they work in different browsers to see that they all work correctly.
But since it is a tool to control browsers, its uses have ended up being many more than testing websites and tools. For example, it can be used for visual regression testing, accessibility auditsAPI testing or performance checks.
It can also be used for web scraping tasks, which is extracting data from web pages automatically, or taking screenshots. And also you can create scripts automaticallybecause it has a recording mode that records the actions performed in the browser to generate the code to execute them whenever you want.
And of course, you can also use it with artificial intelligence. Playwright has become the fundamental piece that many agents use to navigate the Internet. They do this with the Playwright MCP component, which uses the Model Context Protocol so that agents can know the navigation functions and use them.
In practice, this means that tools like Claude Code, Codex, Cursor or VS Code can use the Playwright MCP to control your navigation, converting what you ask them with natural language into actions. You ask the AI to go to a website and download a form, and the agent will use Playwright to access the website and do what you ask.
