In-depth: PostHog vs Mixpanel

Jan 08, 2024

Want to know how PostHog and Mixpanel compare? If you remember nothing else, remember these two points:

  1. Mixpanel is a product analytics tool only.

  2. PostHog is an all-in-one platform that includes product analytics and much more.

How is PostHog different?

1. It's more than product analytics

PostHog is the only product analytics platform built to natively work with session replay, feature flags, A/B testing, and surveys. This means you get all the tools you need to deploy new features, test their performance, observe and analyze how users interact with them, and gather feedback. Everything you need to truly understand user behavior, perfectly integrated.

2. It's built for engineers

We support all popular (and some unpopular) SDKs, have extensively documented APIs, and a powerful SQL query builder, so you can analyze data how you want. We make it easy to test in production, conduct phased rollouts, run beta programs, and so much more.

3. We're open source and transparent

PostHog is built on transparency. Our product is open source and released under an MIT License. You can read our source code, raise issues and PRs, build your own integrations, and vote on our public roadmap. Got a question? Ask it in our community forum.

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.

Frequently asked questions

Can PostHog also replace Google Analytics?

Yes. PostHog can replace Google Analytics for many use cases – our marketing team uses PostHog, for example. You can integrate PostHog into your website using Google Tag Manager. See our comparison of PostHog and Google Analytics 4 and An intro to PostHog for Google Analytics users for more.

Is PostHog easy to deploy?

Yes. Just paste our JS snippet within the <head> tags your product or website and you're good to go in just a few minutes. See our installation documentation for more options. We support dozens of client-side and server-side SDKs.

How much does PostHog cost?

You only pay for what you use and every PostHog users gets a generous amount of free usage each month:

Free usage per month
Product analytics1 million events
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.

We charge progressively less the more you use – e.g. we charge $0.000100 per event up to 2 million events, but all events after 10 million a month only cost $0.000025, 75% less per event.

A full breakdown and pricing calculator is on our pricing page.

How can I estimate my usage?

The easiest way is to sign up to PostHog, integrate our snippet, then check the projection on your billing page after a few days. Alternatively, you can guesstimate by multiplying your current monthly active users by an estimate of events generated per user – 50 to 100 per user is a good starting point. See Estimating usage & costs in our docs for more.

Does PostHog block bots by default?

Yes. See the full blocklist in our docs.

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 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 session replays or surveys, and doesn't offer autocapture, but it does offer feature flags and A/B testing on some paid tiers. Read our PostHog vs Amplitude comparison for information.
