What it solves

SEOmator is a comprehensive SEO audit tool designed to identify technical, performance, and accessibility issues on websites. It automates the process of scanning sites against hundreds of rules to provide prioritized, actionable reports, reducing the manual effort required to optimize a site for search engines and AI-driven discovery.

How it works

The tool scans websites using a combination of static analysis and dynamic rendering (via Playwright) to measure Core Web Vitals and analyze JavaScript-rendered content. It can operate in single-page mode or crawl mode to analyze multiple pages. Results are processed against 332 rules across 20 categories and can be stored in a local SQLite database for history tracking and comparison. The tool is available as a CLI, a desktop Electron app, and a skill for AI coding agents like Claude Code.
