Migrate from PostHog to Zenovay
Read this before you switch. If PostHog is your product analytics backbone, stay on it. If you adopted it mainly for website analytics and the nine-product bundle feels heavier than you need, this guide is for you.
Migration Steps
Decide whether you should actually move
If your team relies on PostHog for deep product analytics, feature-flag-driven release engineering at scale, or its data warehouse, you should probably stay on PostHog or run both. The teams who benefit from moving are the ones who adopted PostHog for website analytics, found the nine-product bundle heavier than they needed, and want something a non-engineer can drive.
Install Zenovay alongside PostHog
Create a free account, add your site, and paste one script tag. Collection starts immediately and the whole install takes about two minutes. Leave PostHog running so both tools see the same traffic while you compare them.
Export your PostHog history yourself
There is no automated PostHog importer yet. Zenovay currently imports from Plausible, Google Analytics 4, Matomo, Simple Analytics and Fathom, and a PostHog importer is planned but not shipped. Historical PostHog data does not transfer automatically today, so use PostHog's batch exports to land your history in your own storage, or keep the PostHog project readable for reference before you cancel.
Rebuild the handful of things you actually look at
Most teams read a fraction of what they track. Recreate your goals, funnels and custom events in Zenovay, connect Stripe for revenue attribution, and add uptime checks. If you run experiments, A/B testing and feature flags are available on Pro and above, and a developer adds one line of JavaScript to read the assigned variant.
Compare for a couple of weeks, then decide
Run both side by side. The numbers will not match exactly because bot filtering, session rules and event definitions differ, and that is expected. Then either switch fully, or settle where many teams land: PostHog for in-product behaviour, Zenovay for marketing, traffic and revenue attribution.

Frequently Asked Questions
Should I actually leave PostHog?
Often, no. If you rely on PostHog for deep product analytics, feature-flag-driven release engineering at scale, or its data warehouse, stay on PostHog. Zenovay is not a replacement for those. The teams who benefit from moving adopted PostHog mainly for website analytics and found the bundle heavier than they needed.
Can I run PostHog and Zenovay together?
Yes, and many teams do exactly that: PostHog for in-product behaviour, Zenovay for marketing, traffic and revenue attribution. This is not a forced either/or. Both are a single script tag, so running both is a normal setup rather than a compromise.
Will I lose my PostHog history?
For now, yes. Historical PostHog data does not transfer to Zenovay automatically. Zenovay has importers for Plausible, Google Analytics 4, Matomo, Simple Analytics and Fathom, and a PostHog importer is planned but not available today. Before you cancel, export your history with PostHog's batch exports or keep the project in a read-only state for reference.
Why is there no PostHog importer yet?
PostHog's own documentation deprecates the events API and steers bulk extraction towards batch exports, which land in your S3, BigQuery or Snowflake rather than anywhere Zenovay can read. The remaining query API is rate limited, at 120 requests an hour on legacy projects and 2,400 on newer ones. A reliable importer has to work around all of that, so it needs to be built carefully rather than quickly.
Do I need an engineer to switch?
Not for the install. It is one script tag in your site's head, roughly two minutes. You will want a developer for one thing: reading the assigned variant in JavaScript if you run A/B tests. Note that in cookieless mode variant assignment is window-scoped and resets when the tab closes, so it suits short in-page tests better than long multi-session experiments.
Try it side by side
Install Zenovay next to PostHog, compare two weeks of real traffic, and decide with your own data instead of a pitch.
