In-depth: PostHog vs Mixpanel
Contents
How is PostHog different?
1. We're an all-in-one platform
PostHog puts all your data in one place and combines it with every tool you need to build a successful product. This means:
- Product analytics for analyzing behavior, funnels, activation, and retention
- Web analytics for tracking your marketing website and content
- Session replay for observing how people use your product and diagnosing problems
- Feature flags for testing in production and shipping new features
- Experiments for verifying improvements to your product and website
- Error tracking for monitoring exceptions and problems in your code
- Surveys for capturing user feedback, tracking NPS, and booking interviews
- A built-in data warehouse for analyzing your business and event data together
In other words, it's everything you need in one app with a single login and contract. A genuine single source of truth for your product and customer data.
2. We build for developers
This means you get support from the engineers who actually build the product, extensively documented APIs, and a SQL query builder, so you can analyze data how you want. We're open source, so you can inspect our source code and vote on what we should build via our public roadmap.
3. We promise transparent and cheap pricing (forever)
We default to charging as little as possible while still making a profit – we also have a generous free tier on all our products. We can do this because we're efficient. We don't splurge on outbound sales, or D-list comedians to host an annual convention you'll never attend. Our pricing is also 100% transparent.
Comparing PostHog and Mixpanel
As an all-in-one-platform, PostHog isn't just an alternative to Mixpanel, it can also replace tools like Hotjar for session replay and surveys, and LaunchDarkly for experiments and feature flags.

Product analytics
PostHog and Mixpanel offer broadly similar product analytics features, including the ability to create insights using natural language.
Our generous free tier means every PostHog customer gets 1 million analytics events for free every single month. More than 90% of companies use PostHog for free, and our startup program comes with $50,000 in credit.
Website analytics
PostHog is also a powerful alternative to Google Analytics that bridges the gap between lightweight tools like Plausible, and expensive enterprise platforms like Adobe Analytics.
You can use the PostHog toolbar to view clickmaps, heatmaps, and scrollmaps for your website. You can also use the toolbar to turn feature flags on and off, debug events, and create no-code experiments.
Session replay
PostHog's session replay can be used by anyone, but it includes numerous developer-level features that make it useful for engineers, product managers, and support engineers who want to diagnose issues, and identify potential improvements.
Library support for replays
Mixpanel only recently introduced session replay, so its mobile SDKs are still in development. PostHog has wide support for all popular web and mobile SDKs.
You can use PostHog AI to chat with your recordings using natural language – e.g. "show me sessions over 5 minutes long" or "show me sessions from users in Belgium". You can also ask PostHog AI to summarize what happened during a session.
Feature flags
Feature flags make it easy to roll out features to specific users or groups, and safely test in production. You can also use them to control access to beta features, and make scheduled changes to your app.
Our feature flags are tightly integrated with other tools, meaning you can target session replays, surveys and other features using existing feature flags. See benefits of feature flags for more.
Experiments
Experiments in PostHog are billed with feature flags.
You can't run A/B tests using Mixpanel, but you can analyze the results of experiments created using third-party testing tools.
You can evaluate the results of experiments using events tracked using PostHog, or event tables stored in our data warehouse. This means you can include all kinds of business event data as primary or secondary metrics in your experiments.
Surveys
You can't build a successful product on data alone. Surveys are useful for gathering feedback and booking interviews, notifying users of changes, and keeping track of customer satisfaction metrics.
Surveys are great for tracking customer satisfaction scores like Net Promoter Score (NPS), customer satisfaction (CSAT), and customer effort score (CES). We include survey templates for all these and more. Read our guide comparing NPS, CSAT, and CES to see which survey type you should use and when.
Price comparison
PostHog and Mixpanel both charge based on the number of events ingested, however:
- Mixpanel charges the same for events generated by identified and anonymous users.
- PostHog charges up to 80% less for events generated by anonymous users.
Anonymous events are the default event type in PostHog, so you only get charged for identified events when you call identify in your code – see our anonymous vs identified events explainer for more on this.
As the below table shows, however, PostHog is cheaper than Mixpanel even if you're only tracking identified users.
| Monthly events | PostHog (100% identified events) | Mixpanel | |
|---|---|---|---|
| 0-1 million | Free | Free | |
| 3 million | $352/month | $378/month | |
| 5 million | $560/month | $612/month | |
| 10 million | $1,080/month | $1,465/month | |
| 15 million | $1,600/month | $1,722/month | |
| 20 million | $1,927/month | $2,289/month |
And it becomes even cheaper if 20% of your events are from anonymous users, which is typical for many of our customers.
| Monthly events | PostHog (20% anonymous events) | Mixpanel | |
|---|---|---|---|
| 0-1 million | Free | Free | |
| 3 million | $310/month | $378/month | |
| 5 million | $490/month | $612/month | |
| 10 million | $940/month | $1,465/month | |
| 15 million | $1,391/month | $1,722/month | |
| 20 million | $1,783/month | $2,289/month |
We recommend tracking your marketing website and product in a single project, and you can track all events on your website anonymously to save money.
| Monthly events | PostHog (100% anonymous events) | Mixpanel | |
|---|---|---|---|
| 0-1 million | Free | Free | |
| 3 million | $84/month | $378/month | |
| 5 million | $153/month | $612/month | |
| 10 million | $324/month | $1,465/month | |
| 15 million | $496/month | $1,722/month | |
| 20 million | $643/month | $2,289/month |
Good to know: Web analytics makes it easy to track and monitor high-level website metrics, like page views, bounce rate, and the top sources of traffic, but you can still create custom product analytics insights and dashboards using anonymous events. See our web vs product analytics explainer for more.
Data integrations
PostHog has a built-in data warehouse, so you can import and query data directly from our other sources like Stripe and Zendesk, or from an existing warehouse.
Mixpanel relies on data warehouse connectors to combine customer and product data. This means you don't import data directly from third-party tools. You need to get them into a third-party warehouse and then import that data into Mixpanel for analysis.
See our docs for full lists of destinations and data warehouse sources.
Security and compliance
A Business Associate Agreement for HIPAA compliance is available for customers with our platforms add-ons. The add-on also includes our managed reverse proxy, priority support, SSO and 2FA enforcement, numerous collaboration features, and support multiple environments within projects so you can separate dev and production data, but use the same insights and dashboards across them all.
Frequently asked questions
Can I migrate my data from Mixpanel to PostHog?

A full breakdown and pricing calculator is on our pricing page.
Can I use PostHog with a CDP? (Segment, Rudderstack, etc.)
Yes. See Using PostHog with a CDP in our docs.
What about ad blockers?
We recommend all users deploy a reverse proxy, which enables you to send events to PostHog Cloud using your own domain. Events sent from your own domain and are less likely to be intercepted by tracking blockers, ensuring you capture the best data possible.
We make this super easy by offering a managed reverse proxy – a no code solution that takes minutes to set up. We also have reverse proxy setup guides for AWS Cloudfront, Caddy, Cloudflare, Netlify, Vercel, and more in our docs.
PostHog is an all-in-one developer platform for building successful products.
