TL;DR
PostHog is a broad, open-source product analytics platform with feature flags, A/B testing, and a data warehouse. Trfyx is a narrower tool that focuses on web analytics, session replay and connecting traffic to revenue — with a simpler setup and interface.
| Topic | Trfyx | PostHog |
|---|---|---|
| Setup | One script tag, under 3 KB gzipped. Tracking starts on paste. | JavaScript snippet or SDK. Autocapture collects events automatically, but meaningful analytics often require configuring actions and properties. |
| Web analytics dashboard | Purpose-built web analytics dashboard: sources, pages, locations, devices, and real-time visitors on one screen. | Web analytics is available as a dedicated view. PostHog's main strength is product analytics (events, funnels, retention). |
| Session replay | Built-in session recordings with masking controls. | Session replay included, with console logs and network tab. Free tier includes 5,000 recordings/month. |
| Revenue attribution | Connect Stripe or Shopify with a read-only key. Revenue appears by source, campaign, and page. | No built-in payment integration. Revenue tracking requires sending custom events with monetary values. |
| Feature flags & A/B testing | Not available. Trfyx focuses on analytics and replay. | Feature flags, A/B tests, and multivariate experiments are core PostHog features. |
| Data warehouse | No built-in data warehouse. Data lives in the Trfyx dashboard. | Built-in data warehouse that can query data from Stripe, Hubspot, Postgres, and other sources. |
| Privacy | One first-party cookie. No third-party data sharing. EU-hosted. | Self-hostable for full data control. Cloud is US-hosted (EU available). Cookieless mode optional. |
| Price | From $9/month with a 20-day free trial. Simple per-plan pricing. | Generous free tier (1M events/month). Usage-based pricing above that. Can get expensive at scale. |

Switching from PostHog
Add the Trfyx script to your site — it works independently of PostHog. If you are using PostHog only for web analytics, you can remove it after confirming Trfyx numbers. If you rely on PostHog feature flags or experiments, keep both.
