Crawler is a free Chrome extension developed by Dollar. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This extension is designed to allow users to crawl and browse all the images of a website in a recursive manner.

One important thing to note is that Crawler does not have the capability to automatically download all the images to your local file system. However, it compensates for this limitation by providing a user-friendly interface within the browser to view these images. In future versions, the developers plan to add functionality to export the data into other formats.

With the recent update to version 1.1, Crawler introduces several noteworthy changes. Firstly, it categorizes the images it retrieves based on their domain, making it easier for users to navigate through the image collection. Secondly, it now includes a URL input box in the manager page, allowing users to change the crawl site as needed. Lastly, Crawler has implemented performance enhancements by implementing lazy loading, ensuring that images are only loaded when they are scrolled into view.
