PostHog's web analytics dashboard includes real-time data with live visitor activity.
Custom Event Tracking
Web Analytics tracks only pageviews/visits; custom event tracking requires the separate Zaraz product.
PostHog supports custom event tracking via JS SDK (posthog.capture()), autocapture, and data attributes.

Cookieless by default — does not use cookies or localStorage to collect usage metrics.

Cloudflare maintains a GDPR trust page and uses EU Standard Contractual Clauses for data transfers.
PostHog explicitly claims GDPR compliance with EU Cloud hosting, DPA, cookieless option, and data anonymization.

The verdict
Cloudflare Web Analytics Best for simple, banner-free privacy traffic counts
The lighter, simpler option: entirely free with no event cap, cookieless by default with no consent banner required, and an 11.2 KB script versus PostHog's 66.7 KB. It also allows 10 sites on the free product against PostHog's single free project. The tradeoff is depth: no custom events, goals, funnels, heatmaps, or real-time view.
Full profile PostHog Best for product analytics depth and data ownership
The deeper, more flexible pick: custom events, conversion goals, funnels, heatmaps, revenue tracking, and a real-time dashboard, none of which Cloudflare Web Analytics offers. It is also MIT open source and self-hostable, with EU data residency, GA import, public dashboard sharing, and 84-month retention versus 6. Costs: a heavier 66.7 KB script and a consent banner by default.
