Run a full SEO check across all your templates with a single command
AI-powered SEO analysis for developers. Scan your templates, spot issues, and fix them — without ever leaving your terminal.
gem install nerima
Run a full SEO check across all your templates with a single command
Checks meta titles and descriptions, heading hierarchy, image alt text, canonical tags, Open Graph, and schema markup across every template file.
Powered by Claude. Goes beyond rule-based checks to give you context-aware suggestions and flag content at risk of being replaced by Google AI Overviews.
Run nerima fix on any file to get a diff of suggested SEO improvements. Review the changes and apply them with a single keypress.
Supports HTML, ERB, Haml, Slim, Liquid, Nunjucks, Jinja2, Twig, and Blade. Configure exactly which files to scan via .seo.yml.
Most SEO tools are designed for marketers — they live in dashboards, require browser logins, and give you scores without telling you what to actually change in the code. Nerima is different. It runs in your terminal, reads your source files directly, and tells you exactly what needs fixing and where.
A single nerima check scans every template in your project in parallel, using AI to catch issues that simple linters miss — thin content, missing structured data, heading hierarchies that will confuse both users and search engines. The AI Overview risk flag goes further, identifying pages where your content is likely to be summarised away by Google before a user ever clicks through.
Nerima slots into your existing workflow. Run it before a deploy, add it to your CI pipeline, or use nerima fix to clean up a single file during development. No accounts, no dashboards, no context-switching — just fast SEO feedback where you're already working.
