Shikiri is a free Chrome extension designed to enhance web browsing by allowing users to display custom labels on specific web pages. This tool is particularly useful for distinguishing between different environments, such as production and development sites, by enabling the display of color-coded labels based on URL patterns. The extension utilizes advanced regular expression matching for precise URL targeting, ensuring flexibility in label application.

Users can customize the appearance of the labels, including text, background color, text color, and opacity, all while maintaining a non-intrusive overlay that does not interfere with page content. Shikiri is ideal for professionals who need to manage multiple sites with similar interfaces, providing visual cues for better navigation and awareness.
