SEObolt SEO Checker (Chrome Extension)

16 KB on-page SEO audit. No account. Runs locally

What it does

16 KB. That's the full install size. SEObolt SEO Checker is 60 to 300 times smaller than MozBar, SEOquake, SEO Minion, and every other major SEO extension on the Chrome Web Store. One click runs an instant on-page audit covering meta tags, Open Graph, Twitter Card, JSON-LD schema, heading hierarchy, image alt text and dimensions, and the internal/external link profile. Every check returns pass, warn, or fail with a specific fix. No account. No paywall. Runs entirely locally in your browser.

Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
