Updated 7 August 2026. When this was first published, Zenovay did not have
feature flags or A/B testing and the comparison table said so. Both shipped since
(feature flags in March 2026, A/B/n experimentation in May 2026, both on Pro and
above), so those rows were wrong and have been corrected. PostHog's experimentation
is still the deeper of the two.
PostHog and Zenovay get compared a lot, but they are solving fundamentally different problems.
PostHog answers: "Which features retain users? Where do people drop off in the onboarding flow? Does variant B of the signup page convert better?"
Zenovay answers: "Which marketing channels bring paying customers? How do visitors from Twitter behave differently from organic visitors? Which blog post generated the most revenue?"
Product analytics vs marketing analytics. Engineering teams vs founders and marketers. If you pick the wrong one, you will be frustrated.
Where PostHog is genuinely better
PostHog has a generous free tier: 1 million events per month. For early-stage startups with engineering resources, that is real value.
PostHog's experimentation is deeper. Multivariate experiments, a much larger experimentation surface, and a data warehouse that lets you join external sources such as your CRM or ad platforms alongside product data. Zenovay has no general-purpose warehouse.
PostHog is open source under MIT license. You can self-host, audit the code, and contribute. Their developer community is one of the most engaged in the analytics space.
If your primary questions are about product engagement, user retention, and feature adoption, PostHog is purpose-built for that.
Where Zenovay fills a different gap
Zenovay is built for the question most founders actually ask every morning: "Where are my customers coming from and which channels are worth my time?"
Connect Stripe and see revenue attribution automatically. No event instrumentation required. No engineering time to set up custom properties. Add one script tag and you have answers in 2 minutes.
Zenovay also includes heatmaps and session replay. PostHog has these too (via their toolbar), but Zenovay is EU-hosted in Germany by default with cookieless tracking. PostHog Cloud defaults to US hosting, with EU as an option on specific plans.
The setup gap
This is where the difference hits hardest in practice.
PostHog is powerful but requires engineering investment. You need to plan your event taxonomy, instrument events in your codebase, configure properties, and build dashboards. For a team with dedicated engineers, that is fine. For a solo founder or small marketing team, it is a barrier.
Zenovay is designed for non-engineers. One script tag. Connect Stripe. See revenue data. The tradeoff is less customization, but for most marketing questions, the defaults are enough.
Feature comparison
| Feature | Zenovay Pro ($20/mo) | PostHog (free to usage-based) |
|---|---|---|
| Focus | Marketing analytics | Product analytics |
| Revenue attribution | Built in (Stripe) | Not built in |
| Heatmaps | Included | Included (toolbar) |
| Session replay | Included | Included |
| Feature flags | Yes, Pro and above | Yes |
| A/B testing | Yes, A/B/n on Pro and above | Yes, plus multivariate |
| Setup time | 2 minutes | Hours to days |
| EU hosting | Default | US default, EU option |
| Open source | No | Yes (MIT) |
| Pricing | Flat tiers | Usage-based |
Can you use both?
Yes, and many teams do. PostHog for product analytics, feature flags, and experiments. Zenovay for marketing analytics, revenue attribution, and heatmaps. They complement each other because they answer different questions.
My recommendation
Choose PostHog if you need product analytics (funnels, retention, cohorts), deep experimentation or a data warehouse are essential, you have engineering resources for setup, or open source and self-hosting matter.
Choose Zenovay if you need marketing analytics and revenue attribution, you want actionable data in 2 minutes without engineering, EU hosting and privacy compliance are priorities, or you prefer predictable pricing over usage-based billing.
Disclosure: I built Zenovay. PostHog is a great tool for product teams. If product analytics is your primary need, use PostHog. If marketing analytics and revenue attribution are what you need, try Zenovay.
