Analytics
PostHog vs Mixpanel
PostHog if you want one tool covering analytics, replays, flags and A/B tests, and you're happy with a developer-first product. Mixpanel if analysis is the job, non-technical people need to build reports, and you already have tools for the rest.
- No affiliate links
- Public pricing only
- Updated by hand
Both track events rather than pageviews, and both answer questions like 'what do people do before they upgrade'. The difference is scope and who the product is designed for.
PostHog ships new products constantly and assumes an engineer is nearby. Mixpanel has spent a decade on reporting for product managers, and it shows in how quickly a non-technical person can build a funnel.
Side by side
PostHog and Mixpanel in short.
PostHog
Open-source product analytics plus session replay, feature flags, experiments, surveys and a data warehouse.
- Free
- Generous free monthly allowance across products; self-hosting available for the open-source edition.
- Paid from
- Usage-based after the free allowance
Good at
- Session replay, feature flags and experiments included rather than bought separately
- Free tier is large enough for most pre-product-market-fit companies
- Open source, with a self-hosted option and SQL access to your own data
Weak at
- Developer-first: setup and instrumentation assume engineering time
- Usage-based billing can spike if you fire noisy events
Mixpanel
Mature product analytics focused on funnels, retention and cohorts.
- Free
- Free plan covering a substantial monthly event allowance.
- Paid from
- Paid plans from roughly $20/month, scaling with events
Good at
- Reporting is the most approachable of the two for product and marketing people
- Retention and cohort analysis are excellent and fast
- Strong warehouse integrations
Weak at
- No session replay, flags or experiments — separate tools required
- Costs climb steeply at high event volumes
The differences
Where they actually diverge.
Pick one
Which one fits you.
Choose PostHog if
- You want to cut three subscriptions down to one
- Engineers own instrumentation and will use flags
- You value an open-source escape hatch
Choose Mixpanel if
- Product managers build their own reports
- You only need analysis, not a platform
- You already run LaunchDarkly, FullStory or similar
When neither is the answer
If nobody has agreed which five events matter, neither tool helps. Write down the activation event first, instrument that, and add the rest later.
Questions
Common questions.
Can these replace Google Analytics?
For product usage, yes and better. For marketing attribution and ad platform integration, no — most teams keep a lightweight web analytics tool alongside.
How do I keep costs down?
Don't send every click. Define a short list of meaningful events, avoid high-cardinality properties, and sample noisy autocapture. Both tools bill on volume, so instrumentation discipline is the cost control.
