LGTM is a Chrome extension developed by Alexander Sulim. This free add-on falls under the category of Browsers, specifically Add-ons & Tools. LGTM enhances the GitHub pull request overview page by printing review statuses as stamp labels.

With LGTM, review statuses become more visible and easily distinguishable. The extension does not replace any existing functionality provided by GitHub but rather complements it. By displaying review statuses as stamp labels, LGTM ensures that the review process is more efficient and streamlined.

Overall, LGTM is a useful tool for developers who rely on GitHub for code review. It simplifies the review process by making review statuses more prominent, allowing for quicker and more effective collaboration.
