PostHog and Mixpanel are both product analytics platforms helping teams understand user behavior and build better products. Both expanded beyond core analytics, but their approaches and feature sets differ.
Mixpanel is a product analytics platform with session replay, heatmaps, A/B testing, and feature flags. It's built for product managers and growth teams who want deep behavioral insights.
PostHog is an all-in-one platform for building successful products. On top of product analytics, it includes error tracking, session replays, experiments, feature flags, surveys, LLM observability, an AI assistant, and more. It's built for engineers and product teams who want everything in one place.
PostHog puts all your data in one place and combines it with every tool you need to build a successful product. This means:
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.
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.
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 D-list comedians to host an annual convention you'll never attend. Our pricing is also 100% transparent.
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.
Good to know: If we don't have something you want now, there's a good chance we're planning on building it already. Visit our public roadmap to see what we're considering, and vote for features and products you're interested in. We ship fast!
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.
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.
PostHog 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. Features include console logs, network request monitoring, a DOM explorer, performance metrics, and the ability to jump directly from errors or funnel drop-offs into relevant replays.
Both PostHog and Mixpanel offer broad SDK support for session replay across web and mobile platforms.
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 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.
Both PostHog and Mixpanel now offer native A/B testing and feature flags. PostHog has had experimentation longer and bills experiments together with feature flags. Mixpanel relaunched experimentation in late 2025 after previously deprecating it – their Experiments report is available as an Enterprise add-on.
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.
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.
PostHog and Mixpanel both charge based on the number of events ingested, however:
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 | $1,176/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 | $1,176/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 | $1,176/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.
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.
A Business Associate Agreement for HIPAA compliance is available for customers with one of our platform packages. The packages also include priority support, SSO and 2FA enforcement, numerous collaboration features, and support for multiple environments within projects so you can separate dev and production data, but use the same insights and dashboards across them all.

Mixpanel is a product analytics platform that has expanded to include session replay, heatmaps, A/B testing, and feature flags. It's optimized for product managers and growth teams. PostHog is a broader all-in-one platform that combines product analytics with error tracking, LLM observability, surveys, and more – built primarily for engineering-led teams who want everything in one place.
Yes, for most teams. PostHog offers all of Mixpanel's core analytics features (funnels, retention, cohorts, user paths) plus additional tools like error tracking, LLM observability, and surveys. If you're an engineering-led team that values SQL access, open-source code, and transparent pricing, PostHog is a strong replacement.
Consider keeping Mixpanel if your team is heavily invested in Mixpanel's metric trees for goal alignment, you prefer their polished UI for non-technical users, or you're using warehouse-native analytics with Mixpanel sitting directly on your data warehouse.
Mixpanel has three tiers:
Add-ons like Group Analytics, Data Pipelines, and Experiments are separately priced. Session Replay is included but limited by recording count. For comparison, PostHog's pricing is fully transparent with no hidden add-on costs.
Both offer solid session replay with web and mobile support. PostHog includes more developer-focused features like console logs, network request monitoring, DOM explorer, and performance metrics. Mixpanel added AI-powered replay summaries and heatmap comparison mode in late 2025. PostHog's free tier includes 5,000 replays/month; Mixpanel's replay limits depend on your plan.
Yes, though most teams find it redundant. If you're migrating gradually, you can run both in parallel. PostHog can also receive data from Mixpanel via our Mixpanel to PostHog migration guide, or you can send PostHog data to Mixpanel using our CDP.
The top all-in-one product analytics platforms in 2026 include:
Both support group/account-level analytics for B2B use cases. Mixpanel recently added Account Profiles and Activation Metrics specifically for B2B analysis (requires Group Analytics add-on). PostHog includes group analytics on all plans, plus you can connect it to CRM data via the built-in data warehouse. PostHog is often preferred by B2B teams that also need feature flags and experiments for enterprise rollouts.
Yes, as of late 2025. Mixpanel relaunched feature flags alongside their Experimentation 2.0 release. However, feature flags are newer in Mixpanel compared to PostHog, which has had them longer with more mature functionality like local evaluation, bootstrapping, early access management, and scheduling.
No. Mixpanel does not offer error tracking or crash reporting. If you need to monitor exceptions alongside your analytics, you'd need a separate tool like Sentry or Bugsnag. PostHog includes error tracking natively, connected to session replays and user behavior data.
No. Mixpanel doesn't offer AI/LLM observability features. PostHog includes LLM observability for tracking AI product usage, monitoring model performance, analyzing token costs, and debugging LLM interactions – useful for teams building AI-powered features.
Both are designed for quick implementation. PostHog offers an AI install wizard that gets you running in under 90 seconds, plus autocapture that starts collecting events immediately. Mixpanel also supports autocapture and has straightforward SDK installation. The main difference is PostHog's broader feature set means there's more to explore, but you can adopt features incrementally.
Different approaches. Mixpanel connects to external warehouses to import data and run queries in Mixpanel. PostHog offers an integrated data warehouse approach: you can use PostHog as your warehouse (data stays in PostHog and is accessible across all PostHog tools), or connect external warehouses (like Snowflake or BigQuery) as sources to sync the tables and fields you need into PostHog. Either way, queries run on PostHog compute.
PostHog is better if:
Mixpanel's approach is better if you have a limited use-case and need to keep data in an existing, external warehouse for compliance reasons.
Companies like HeadshotPro and Webshare use PostHog's integrated warehouse as their single source of truth, eliminating the need to stitch together multiple vendors.
PostHog charges up to 80% less for anonymous events, so tracking your marketing website anonymously significantly reduces costs. You can also set billing limits per product to avoid surprises. Mixpanel charges the same rate for all events. Both offer free tiers (PostHog: 1M events; Mixpanel: 1M events with credit card). See our pricing page for a detailed calculator.
PostHog offers direct support from the engineers who build the product – you can often get help from the person who wrote the code you're asking about. We also have active community forums and extensive documentation. Mixpanel has traditional tiered support with faster response times on higher plans.
PostHog is generally better for early-stage startups. The generous free tier covers most startup needs, and the PostHog for Startups program offers $50k in additional credits. More importantly, you get a single platform that scales from MVP to growth stage without needing to add tools as you grow. Mixpanel also has a startup program, but you may need additional tools for feature flags, experiments, error tracking, and surveys.
Yes. See our Mixpanel to PostHog migration guide.
Yes. PostHog can replace Google Analytics for many use cases – our marketing team uses PostHog, for example. You can also 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.
Every PostHog user gets a generous amount of free usage each month: 1 million events for product analytics, 1 million synced rows for the data warehouse, 5,000 session recordings, 1 million API requests each for feature flags and A/B testing, and 1,500 survey 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.
Yes. PostHog includes a built-in CDP that lets you import, transform, and export data without needing a separate tool. You can also integrate PostHog with third-party CDPs like Segment and Rudderstack.
See our docs on using PostHog with a CDP for setup instructions, or browse our comparison of the best customer data platforms for developers if you're evaluating options.
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.
