In-depth: PostHog vs Mixpanel

Jul 19, 2024

How is PostHog different?

1. We're an all-in-one platform

PostHog combines product analytics with web analytics, session replay, feature flags, A/B testing, surveys, and a data warehouse into one tightly integrated platform. Everything you need from a single app with a single contract. A genuine single source of truth for your product and customer data.

2. It's built 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. 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 massive sales teams, or D-list comedians to host an annual convention you'll never attend. Want to know how much we'll charge? See our pricing calculator.

Product analytics

There are two key differences here:

  1. PostHog supports autocapture, which makes it much faster to implement as you don't have to manually instrument every event. Don't want autocapture? Just turn it off and rely on one of our many SDKs – we offer the best of both worlds.

  2. PostHog has a SQL-based query builder for power users, which enables you to generate custom data analyses using PostHog event data. In future, our query builder will let you analyze data as you would in a business intelligence tool, like Metabase, inside PostHog.

Feature flags

Feature flags make it easy to roll out features to specific users or groups, and safely test in production. Our feature flags are also 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.

Data integrations

PostHog and Mixpanel diverge here:

  1. 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.

  2. 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.

Frequently asked questions

Can I migrate my data from Mixpanel to PostHog?

Yes. See our Mixpanel to PostHog migration guide.

Can PostHog replace Google Analytics?

See our comparison of PostHog and Google Analytics 4 and An intro to PostHog for Google Analytics users for more.

How much does PostHog cost?

Every PostHog user gets a generous amount of free usage each month:

 Free usage per month
Product analytics1 million events
Data warehouse1 million synced rows
Session replay5,000 recordings
Feature flags1 million API requests
A/B testing1 million API requests
Surveys250 responses

You'll never pay anything if you stay within these limits and you can set billing limits to avoid surprise bills.

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 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 setup. We also have reverse proxy setup guides for AWS Cloudfront, Caddy, Cloudflare, Netlify, Vercel, and more in our docs.

How do PostHog and Mixpanel compare to Amplitude?

Amplitude is closer to Mixpanel than PostHog – it doesn't support features like session replays or surveys, and doesn't offer autocapture. Read our PostHog vs Amplitude comparison for information.
