• Generous free tierPostHog offers a generous free tier for all its products, with more than 90% of companies using PostHog for free. The free tier includes 1 million events per month for Product Analytics, 5,000 recordings for Session Replay, 1 million requests for Feature Flags, and 1 million rows for the Managed warehouse, among other products.
• Usage-based pricing with volume discountsPostHog's pricing is transparent and usage-based, with prices that decrease as your volume increases. For example, Product Analytics starts at $0.00005 per event after the free tier, but drops to $0.000009 per event for volumes over 250 million events per month. This makes PostHog a cost-effective choice at scale.
• No credit card required to startYou can start using PostHog for free without providing a credit card. The free plan includes 1 project, 1-year data retention, unlimited team members, and community support. You only need to add a credit card if you exceed the free tier limits or want advanced features like more projects or longer data retention.
• Billing limits for cost controlPostHog allows you to set a billing limit for each product, ensuring you never get an unexpected bill. This is particularly useful for teams that want to control costs while scaling their usage.

• Free tier limits apply per productThe free tier limits are per product and reset monthly. For example, you get 1 million events for Product Analytics, 5,000 recordings for Session Replay, and 1 million requests for Feature Flags each month. If you exceed any of these limits, you will be charged usage-based pricing for that product.
• Pricing varies by product and volumeEach product has its own pricing structure. For instance, Session Replay charges per recording, while Error Tracking charges per exception. Prices also decrease with volume, but the exact rates differ by product. Always check the specific pricing table for the product you plan to use.
• Some products are billed with othersCertain products are billed together. For example, Web Analytics is billed with Product Analytics, and Experiments are billed with Feature Flags. This means usage of these products counts toward the same free tier and pricing tiers, so you should consider combined usage when estimating costs.
• Data retention and project limits differ by planThe free plan includes 1 project and 1-year data retention. Upgrading to a paid plan gives you 6 projects and 7-year data retention. If you need more projects or longer retention, you'll need to upgrade, which requires adding a credit card.

Product Analytics

PostHog's Product Analytics tool tracks up to 1 million events per month for free, with usage-based pricing starting at $0.00005 per event. It helps teams understand which features customers use and how they interact with the product, enabling data-driven decisions.

Session Replay

Session Replay records user sessions (5,000 recordings free monthly, then $0.005 per recording) to let you watch exactly how users navigate your product. This visual insight helps identify usability issues and friction points, improving the overall user experience.
