Why PostHog Matters
If you're weighing PostHog 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. We've fingerprinted PostHog on 14 live sites in our database, so the answers here are grounded in real scan data — not marketing copy.
How Websites Using PostHog 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 PostHog
Based on patterns in our scan dataset and the detection evidence tiers.
- →Start by running a PostHog 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/posthog) to see how PostHog sites look in the wild and spot the design patterns that repeat across real deployments.
- →For migration planning, compare PostHog against other builders in the same category — feature parity usually matters more than raw popularity.
