Laser Eyes is a free Chrome extension developed by dthunziker that aims to assist front-end developers in visualizing elements in the DOM. This handy tool injects custom CSS onto the current tab, allowing developers to easily see how elements align and stack up. Unlike other similar extensions, Laser Eyes uses the "outline" property instead of "border" to avoid any unwanted changes in element size and preserve the original alignment.

One of the standout features of Laser Eyes is its ability to customize the injected CSS, giving developers full control over the visual representation of the elements. Additionally, this customization is synced across multiple browsers, making it convenient for developers who work on different devices or collaborate with others. With Laser Eyes, front-end developers can streamline their workflow and efficiently identify any issues with element alignment and stacking.

Overall, Laser Eyes is a valuable tool for front-end developers who want to optimize their development process by easily visualizing and analyzing elements in the DOM. Its customizable CSS injection and cross-browser sync feature make it a must-have extension for any developer working on Chrome.
