Methodology

How the scoring works.

Every score on this site is computed from published data using the weights on this page. And this page published before any verdict carried weight, so you can hold us to it.

Why the rubric published first

Most comparison sites work backwards: pick the winner, usually whoever pays the highest commission, then justify it. SiteVersus has no affiliate links, so the only way to prove that is to show the machinery. If you disagree with a verdict, you can see exactly which inputs produced it, and tell us which input is wrong.

What we compare

Website platforms a real team might build on in 2026: hosted builders (Wix, Squarespace), hosted CMSs (Webflow, Shopify), self-hosted CMSs (WordPress, Drupal, Joomla), and headless systems (Contentful, Sanity, Strapi). Each platform’s type is listed prominently: comparing Wix to Strapi head-to-head is a category error, and the tool says so instead of pretending one wins.

The data model

  • 111 attributes per platform across 14 categories: pricing, editor, design, hosting, performance, SEO controls, content, ecommerce, ownership and lock-in, extensibility, AI, collaboration, support, and multilingual.
  • Every factual claim carries a source URL and a verified date. Official vendor documentation and pricing pages are the preferred source; hands-on testing fills the gaps. We never cite other comparison or affiliate sites.
  • A handful of attributes are explicitly editorial (learning curve, design flexibility, lock-in risk, documentation quality) and are labeled as judgments with reasoning, never presented as facts.
  • Unverified is shown as unverified. We never guess silently.

Scoring: no single winner

Each scored category rolls up to a 0–5 from its attributes; editorial attributes never contribute more than 20% of a category score. There is no global “best platform” number, because a single overall score is how affiliate sites launder bias. Verdicts are use-case-weighted: category scores multiplied by the weight profile for what you are actually building.

Sourcing and verification

  • Priority order: official pricing and docs pages → hands-on testing → vendor changelogs → independent measurement such as HTTP Archive’s Core Web Vitals data. Never other comparison sites.
  • Prices are USD, US market, annual-billing monthly equivalents. Intro-versus-renewal pricing games get their own attribute.
  • Rolling corrections as vendors ship; a full re-verification sweep every quarter. Every page shows its data’s verified dates.

Neutrality rules

  • No affiliate links today: none, not disclosed-affiliate, not “partner” links. If that ever changes, it will be announced on the changelog, disclosed on every link, and scores will keep coming from this public rubric, which is version-controlled, so you can check.
  • No sponsored placements, no pay-for-listing, no vendor-supplied scores.
  • SiteVersus is built by K Squared Consulting, an agency that builds client sites on many of these platforms. That is the point: we live with these tools’ consequences.
  • We don’t edit Wikipedia or seed citations ourselves.

The conflict of interest, pre-committed

K Squared builds a CMS: BrightSite. It is brand new and early in its development, still building out core features. That is exactly why it is deliberately not listed at launch: scoring it honestly today would mostly document what it does not do yet. If and when it is mature enough to be added:

  • It will be labeled “our product” on every page where it appears.
  • It will be scored against this rubric as published before its listing; the version-controlled dataset proves which came first.
  • It gets no weight changes, no new categories, and no new attribute definitions in the release that adds it.
  • Its data gets the same per-claim sourcing, and disputes about its cells go through the same corrections process as everyone else’s.
