seo_rat
Why seo_rat?
Most SEO tools cost $100+/month and are built for WordPress. If you build with Astro, Quarto, or nbdev — there’s nothing for you.
seo_rat is a free, open-source alternative that runs locally, uses your real Google Search Console data, and is designed to work with AI coding agents without wasting tokens.
There are two camps in SEO right now: 1. People stuffing content with AI-generated keywords 2. People saying AI SEO is all garbage
We take a third path — context-aware optimization with a human in the loop. The tool surfaces real opportunities from your data; you decide what to act on.
Three ways to use it: - CLI for power users - Web app (coming soon, powered by HTMX) - Notebooks for experimentation (via nbdev)
Principles: - Real GSC data, no artificial limits - Surface content gaps based on your site’s goals, not generic keyword stuffing - Minimal token usage — designed for coding agents - Not locked to any paid AI provider
