Why another SEO extension?
Daily SEO work usually means: one tool for meta tags, a second for schema, a third for readability, a fourth for backlinks. Three of them crawlers only — none of them give you real-time data on the one page actually in front of you. SEOMURAI was built to close exactly that gap.
Open any page, click the icon, and see it all at once: SEOMURAI score, the five most critical issues, a full tech-SEO audit, content analysis, and a link overview. No crawl, no account, no waiting. Built by minoka.de for people who make websites better every day.
Your DataForSEO data, your costs, no markup.
SEOMURAI uses the BYOK model (Bring Your Own Key): you enter your own credentials in the settings and are billed directly by DataForSEO, OpenRouter, OpenAI, and the other providers per query. We never see your data, we don’t add any markup, and there are no quotas we need to sell you.
Privacy isn’t a feature. It’s a prerequisite.
SEOMURAI is built on the principle of data minimization. All analyses run locally in your browser. Data leaves your machine only if you configure a webhook yourself or use an API provider with your own keys.
- All analyses run exclusively in your browser.
- No tracking.
- API keys are stored only in your browser’s
chrome.storage. - Tracker Blocker is disabled by default, opt-in.
