Built by people who live with the consequences.

Search “best website builder” and nearly every result is an affiliate storefront: the ranking is a price list, and the price is paid by the platforms, not the reader. The tools that once did this honestly, like the CMS Matrix that ran from 2003 to roughly 2015, went stale and disappeared from view. SiteVersus is a maintained successor to that idea: a comparison you can audit instead of a ranking you have to trust.

K Squared Consulting is a US web and SEO agency. We build, migrate, and maintain client sites on WordPress, Wix, Squarespace, Webflow, Shopify, and the rest of the roster, which means we hit these platforms’ limits, billing surprises, and export screens on real projects, on someone else’s deadline.

That is the disclosure and the qualification in one sentence. The dataset is maintained by the K Squared team, in version control, with every claim carrying its official source and the date we verified it.

• No affiliate links, no sponsored placements, no pay-for-listing. None.
• The scoring rubric is public on the methodology page, published before any verdict carried weight.
• Corrections, re-verifications, and additions are logged on the public changelog. Confirmed errors are fixed within 72 hours.
• K Squared also makes a CMS, BrightSite. It is not listed here, and the rules for if it ever is are pre-committed in the methodology’s conflict-of-interest clause.

K Squared builds on every platform in this matrix. If you want the decision made and executed: ksquaredconsulting.co. That link is the only thing this site sells.
