WebRun DevTools is a Chrome browser extension that allows developers to write browser automation and testing scripts directly within HTML pages or notebooks. This extension, developed by m.kotelnikov, provides a seamless integration for developers to perform testing and automation tasks without the need for external installations in a NodeJS environment.

With WebRun DevTools, developers can access the same features as standalone tools like Playwright or Selenium, but without the overhead of heavyweight external installations. This extension offers an API library that interacts with the extension, providing developers with a wide range of capabilities for browser automation and testing.

One notable feature of WebRun DevTools is the safeguarding of API access. The extension generates a unique key that remains within the user's environment, ensuring the security and privacy of the user's scripting activities.

If you're a developer looking for a convenient and efficient way to perform browser automation and testing tasks within HTML pages or notebooks, WebRun DevTools is a valuable extension to consider.
