Should I use Google Analytics or PostHog?

Use Google Analytics for free, unlimited-scale traffic analytics tied to Google Ads; use PostHog if you want product analytics, session replay, feature flags, and error tracking bundled into one open-source platform.

Can PostHog replace Google Analytics?

Yes for product-usage tracking, and PostHog adds session replay, feature flags, and error tracking Google Analytics doesn't offer, though PostHog's data shows no native Google Ads integration.

Does Google Analytics or PostHog offer self-hosting?

PostHog does, with an MIT-licensed core available to self-host or run on a managed US or EU cloud; Google Analytics has no self-hosted option since GA4 is hosted by Google only.

Google Analytics vs PostHog (2026)

By Noahlast updated September 14, 2026

Verdict: Choose Google Analytics if you want free, unlimited-scale traffic analytics tied directly to Google Ads. Choose PostHog if you want one platform bundling product analytics, session replay, feature flags, and error tracking, with an open-source, self-hostable core. The deciding factor is breadth versus flat-free pricing: PostHog replaces several separate tools with one product but bills each usage-based (events, replays, flags, and more), while Google Analytics stays entirely free at any traffic scale for site-level reporting.

Google Analytics vs PostHog pricing: which costs less?

Google Analytics is free at any traffic scale, while PostHog is free only up to 1M events and 5,000 session replays a month, after which each product (events, replays, flags, surveys, data warehouse) bills separately on a usage-based rate.

PostHog's per-product pricing declines at higher volume, for example analytics events run from $0.00005 each at low volume down to $0.000009 above 250 million a month, but because several products bill independently, total monthly cost is harder to forecast than Google Analytics' flat-free model. Google Analytics only introduces a paid tier at custom-priced 360, aimed at large organizations needing unsampled data and SLAs.

Which bundles more product tools, Google Analytics or PostHog?

PostHog bundles far more: product analytics, session replay, feature flags and A/B testing, error tracking, surveys, and a data warehouse in one platform, while Google Analytics is scoped specifically to traffic and marketing analytics.

This breadth is PostHog's core positioning, replacing separate point tools like Mixpanel, Amplitude, and Sentry with one product. Google Analytics' data describes no equivalent bundled feature set, focusing instead on event-based site analytics tied closely to Google Ads for campaign measurement.

Which is easier to use, Google Analytics or PostHog?

Both are rated a moderate learning curve in this data, though PostHog's breadth of bundled tools means new users face a wider surface area to learn than Google Analytics' more narrowly scoped reporting.

Which can be self-hosted, Google Analytics or PostHog?

PostHog can be self-hosted, with an MIT-licensed core available on GitHub; Google Analytics has no self-hosted option since GA4 is hosted by Google only.

Strengths and weaknesses

Google Analytics

Pros

Free for businesses of any size, with no meaningful traffic cap for most use cases.
Deep, native integration with Google Ads for tying analytics directly to campaign performance.
Cross-platform (web + app) tracking in a single GA4 property.
Machine-learning-driven insights (predictive metrics, anomaly detection) built in at no extra cost.

Cons

GA4's event-based model and menu reorganization created a steep relearning curve versus the older Universal Analytics.
Standard (free) properties apply data sampling and shorter data-retention windows than the paid 360 tier.
Google Analytics 360 pricing is not published and requires a sales conversation, making budgeting difficult upfront.
Some users report GA4 reports are harder to pull and customize compared to the legacy interface.

PostHog

Pros

Combines analytics, session replay, feature flags, error tracking, and surveys in one platform.
Generous free tier: 1M analytics events and 5,000 session replays per month with no credit card required.
MIT-licensed core with source available on GitHub, plus a dedicated posthog-foss repository for strictly open-source use.
Choice of US or EU cloud region, or self-hosting.

Cons

Usage-based pricing spans multiple products independently, making total monthly cost harder to forecast than flat per-seat pricing.
Some enterprise features are gated behind a separate proprietary license (the 'ee' directory), not the fully open-source core.
Self-hosting PostHog at scale requires more operational overhead than using the managed cloud.
The breadth of bundled tools (analytics, replay, flags, surveys, data warehouse) means new users face a wider surface area to learn than a single-purpose analytics tool.

Which fits your use case?

Early-stage product wanting a generous multi-product free tier with no credit card	PostHog	PostHog's free tier covers 1M events, 5,000 replays, and 1M feature flag requests a month with no card required.
Team wanting a choice of EU data residency for analytics	PostHog	PostHog offers a managed cloud in either a US or EU region; Google Analytics' data doesn't describe an equivalent region choice.
High-traffic marketing site wanting a cost ceiling that never grows with volume	Google Analytics	Google Analytics stays free at unlimited traffic scale, while PostHog's usage-based pricing grows with event, replay, and flag volume.
