The verdict
Cloudflare Web Analytics Best for free, basic traffic counts across many sites
Cloudflare Web Analytics is entirely free with no paid tier, where Seline runs $14/month and offers no free plan. It also covers up to 10 sites per account versus Seline's 1 site per subscription. The trade-off is scope: pageviews and visits only, with no real-time view, custom events, funnels, or revenue tracking, and history capped at 6 months.
Full profile Seline Best for product, conversion, and revenue analytics
Seline adds the capabilities Cloudflare's free product lacks: a real-time dashboard, custom events, goal and funnel tracking, and ecommerce revenue attribution. It keeps data with unlimited retention versus 6 months, hosts in the EU with data residency, ships an official WordPress plugin, and allows public dashboard sharing. Costs $14/month and covers one site.
