Free SEO tools you can run on your own Next.js deployment
Mix keywords, generate slugs in any language, build hreflang tags and crawl your site for SEO issues. No sign-up, no API keys and no tracking.
Keyword Mixer
Combine up to four word lists (services × cities × modifiers) into every long-tail keyword combination. Runs entirely in your browser.
Bulk Slug Generator
Turn hundreds of titles into clean URL slugs. Handles Turkish, Arabic, Cyrillic and accented characters, with ASCII or native-script output.
Hreflang Generator
Generate validated hreflang tags as HTML link tags, XML sitemap entries or an HTTP Link header. The output is exactly the tags, nothing else.
Site Crawler
Crawl a site from your own deployment and find missing titles, meta descriptions, H1s, image alt text and broken links. Export to CSV.
