PostHog Interactive Demo
Explore a demo of Posthog, an open-source product analytics platform designed to help businesses track and understand user behavior within their apps.
What is Posthog?
PostHog is an open-source product analytics platform that combines event tracking, session replay, feature flags, A/B testing, and user surveys in a single self-hostable product. Founded in 2020 by James Hawkins and Tim Glaser (Y Combinator W20), PostHog has grown to over 50,000 companies — from startups to enterprises like Airbus and Hasura.
Unlike cloud-only analytics tools, PostHog can be self-hosted on your own infrastructure, giving teams complete ownership and control of their data. This makes it particularly popular with European companies requiring GDPR compliance and technical teams with data sovereignty requirements.
PostHog's all-in-one approach means product teams can analyze funnels, watch session recordings, run A/B tests, and control feature rollouts in one tool — without stitching together multiple vendors.
How to get started with Posthog
- 1
Create your PostHog account
Sign up at posthog.com — 1 million free events per month on PostHog Cloud. Or deploy self-hosted on your own infrastructure via Docker Compose or Kubernetes.
- 2
Install the PostHog SDK
Install posthog-js for web apps or mobile SDKs for iOS/Android. Add your project API key and PostHog host URL. Autocapture automatically tracks clicks, form submissions, and pageviews.

Capture custom events
Call posthog.capture('event_name', {properties}) for custom actions. Define an event taxonomy — the specific events and properties your team will track consistently.
- 4
Build funnels and retention charts
Create Funnel Insights to see where users drop off in key flows. Build Retention tables to measure how many users return on subsequent days. Drill into user lists to see exactly who converted or churned.
- 5
Add feature flags and experiments
Create feature flags to roll out new features gradually. Run A/B tests by splitting users across flag variants. Analyze experiment results with PostHog's statistical significance calculations.
Who is PostHog most useful for?
Product engineers and technical product teams who want complete ownership of their analytics data with the ability to extend and customize the platform. Use Supademo to document your team's PostHog instrumentation standards and event taxonomy for consistent analytics tracking.
Startups and scale-ups that want to avoid vendor lock-in and data privacy complexity. PostHog's generous free cloud tier and self-hosting option give maximum flexibility.
Growth teams doing experimentation who want feature flags and A/B testing in the same tool as their analytics — avoiding the data sync complexity of using separate tools.
European SaaS companies that need GDPR-compliant analytics with EU data residency.

FAQs on Posthog
Commonly asked questions about Posthog. Have more? Reach out and our team will be happy to help.
Is PostHog free?
Yes. PostHog Cloud offers 1 million free events, 5,000 session recordings, and 1 million flag evaluations per month. Paid tiers start at $0.000045/event above the free tier. Self-hosting is free with no limits.
Can PostHog be self-hosted?
Yes. PostHog is fully open-source (MIT license) and can be deployed on your own servers using Docker Compose or Kubernetes. Self-hosting gives complete data ownership with no limits on event volume.
Does PostHog have session recording?
Yes. PostHog Session Replay records full user sessions including clicks, scrolls, and network requests. Recordings are tied to your analytics events and user profiles so you can jump from a funnel drop-off directly to a recording of that user's session.
How do PostHog feature flags work?
Feature flags let you control who sees a feature with Boolean flags (on/off), multivariate flags (multiple variants), or percentage rollouts. Flags can target specific user properties, cohorts, or be rolled out gradually to reduce risk.
Is PostHog GDPR compliant?
Yes. PostHog Cloud has EU hosting available. Self-hosting keeps all data on your infrastructure with no data leaving your environment. PostHog supports person property deletion and opt-out for user consent compliance.
What is the difference between PostHog and Mixpanel?
PostHog is open-source and self-hostable with feature flags and A/B testing built in. Mixpanel is cloud-only with more polished analytics UI. PostHog is preferred by technical teams; Mixpanel by product and growth teams who prioritize analytics depth.
