Most SEO extensions either require an account, send your page data to a remote server, or bolt on AI features you didn't ask for. SEOTyde does everything with plain, transparent, client-side JavaScript — you can read exactly what it does because nothing leaves your browser except the specific URLs you choose to check in Competitor Compare or the link checker.


Bloggers, indie developers, freelance SEO consultants, small business owners, and anyone auditing their own or a client's website.
