Comments
Hey everyone! 👋 I built SEOTyde after getting tired of switching between five different tabs just to check a page's title length, meta description, alt text, and heading structure before hitting publish. It runs 100% inside your browser — no account, no AI calls, and no data ever sent to a server. The only network requests it ever makes are URLs you explicitly type in for the Competitor Compare or broken-link checker — nothing else. What's inside: a 100-point SEO score, live Google/social preview, page speed check, broken link scanner, competitor comparison, readability + keyword density highlighting, local score history, and one-click Markdown export. Free, forever, on both Chrome and Firefox. Would love your feedback — especially on what to build next!
