+      "Plausible Analytics has earned a strong reputation as a lightweight, privacy-first alternative to Google Analytics. Its simple dashboard and cookie-free tracking make it a great choice for bloggers and content sites that need basic traffic metrics without the complexity. But as your product grows, you'll quickly hit the limits of what Plausible can offer.",
+      "OpenPanel shares Plausible's commitment to privacy — cookie-free tracking, no consent banners, and EU-based data processing — but goes significantly further with full product analytics capabilities. Where Plausible gives you pageviews, referrers, and country breakdowns, OpenPanel adds funnels, retention analysis, cohort breakdowns, user profiles, and A/B testing. It's the best of both worlds: Plausible-style simplicity for web analytics combined with Mixpanel-style depth for product analytics.",
+      "Self-hosting is another area where OpenPanel has a clear advantage. Plausible Community Edition requires you to set up and manage PostgreSQL and ClickHouse separately. OpenPanel runs in a single Docker container, making deployment and maintenance far simpler. And unlike Plausible, OpenPanel offers a permanent free cloud tier with 10,000 events per month — no credit card required.",
+      "If you've outgrown simple web analytics and need to understand how users actually interact with your product — without adding a second analytics tool — OpenPanel is a natural next step from Plausible."
