Hexometer

Hexometer is a website monitoring tool that checks for issues related to performance, availability, and configuration. The system functions by performing automated checks across multiple layers of a website, including availability monitoring for uptime, content analysis, and source code inspection. Its capabilities extend to monitoring specific HTML elements, keywords, and changes in a site's technology stack. The software also monitors external signals such as backlinks, sitemaps, RSS feeds, APIs, and domain WHOIS records to provide a broad overview of a site's operational health. The tool is used by website administrators, DevOps teams, and SEO specialists. A common workflow involves a site reliability engineer configuring availability and API monitoring to receive immediate alerts on downtime or service errors. SEO professionals utilize the platform to track keyword performance, identify broken links, and analyze changes in the backlink profile to maintain search rankings. Additionally, webmasters can monitor for visual or content discrepancies on key pages, ensuring the user experience remains consistent and error-free.
