Compare

Side-by-side comparison of two websites across 11 typed dimensions. One call captures both sites and returns a scaffold with per-dimension comparability. Produces one finding per dimension.

When to Use

• Compare two competing sites (framework, performance, security)
• Audit staging vs production
• Benchmark a site against a competitor across all 11 dimensions
• Identify gaps where one site excels and the other falls short

The 11 Dimensions

framework, performance, security, seo, accessibility, error-surface, third-party-load, architecture, content-delivery, mobile-readiness, data-structure.

Protocol

Acquire -> Normalize -> Analyze with Evidence Mode.

1. Connect

connect_tab({ url: "https://site-a.com", background: true })

comparePages handles navigation to both sites internally.

2. Acquire + Normalize

const comparison = await smart.comparePages(
  "https://site-a.com",
  "https://site-b.com"
);
// comparison.siteA / siteB — full PageEvidence (capture, performance, security, etc.)
// comparison.scaffold.dimensions[] — 11 objects: { name, comparable, siteA.type/value, siteB.type/value }
// comparison.scaffold.sharedFields / missingFields
// comparison.siteA.gaps[] / siteB.gaps[] — what failed per site

3. Analyze — produce findings

Walk the scaffold. One finding per dimension.

for (const dim of comparison.scaffold.dimensions) {
  if (!dim.comparable) {
    smart.finding({
      claim: `${dim.name}: not comparable — data missing`,
      evidence: [`siteA: ${dim.siteA.type}`, `siteB: ${dim.siteB.type}`],
      sourceUrl: comparison.siteA.capture?.url || "unknown",
      confidence: "low", method: "comparePages", dimension: dim.name
    });
    continue;
  }
  smart.finding({
    claim: `${dim.name}: both sites present — ready for comparison`,
    evidence: [
      `siteA (${dim.siteA.type}): ${JSON.stringify(dim.siteA.value)}`,
      `siteB (${dim.siteB.type}): ${JSON.stringify(dim.siteB.value)}`
    ],
    sourceUrl: comparison.siteA.capture?.url || "unknown",
    confidence: "high", method: "comparePages", dimension: dim.name
  });
}
