Why Dub Matters
If you're weighing Dub for a new site, auditing a competitor's stack, or figuring out why a prospect's website looks the way it does, the platform choice drives everything downstream: hosting cost, SEO control, performance ceiling, and migration pain later. Our detector is scanning the web for Dub signals continuously — real examples appear below as they're discovered.
How Websites Using Dub Work
- Recognizable runtime and asset loading patterns
- Consistent layout or component conventions across projects
- Platform-specific deployment and publishing workflow
Best Practices When Working With Dub
Based on patterns in our scan dataset and the detection evidence tiers.
- →Start by running a Dub detection scan on any URL you're evaluating — the 80+ signal engine returns a confidence score plus the exact markers it matched, which beats reading view-source by hand.
- →Cross-check the result against the full detection evidence in /how-scores-work — confidence tiers tell you whether a match is strong (headers + scripts) or circumstantial (a single HTML pattern).
- →Pair this page with the builder gallery (/gallery/dub) to see how Dub sites look in the wild and spot the design patterns that repeat across real deployments.
- →For migration planning, compare Dub against other builders in the same category — feature parity usually matters more than raw popularity.
