PostHog Pricing Model Overview: Usage-Based, Per-Product
PostHog operates on a multi-product, usage-based pricing model where you pay separately for each feature you use. Unlike traditional analytics platforms with flat-rate pricing, PostHog charges based on specific usage metrics tied to individual products:
- Product Analytics: Charged per event (every user action tracked)
- Session Replay: Charged per recording (every user session captured)
- Feature Flags: Charged per flag decision/request
- A/B Testing: Charged per experiment variant exposure
- Surveys: Charged per survey response
You only pay for what you actually use. If you enable Feature Flags but don’t use Session Replay, you won’t be charged for recordings. However, costs scale immediately with growth, and volume discounts are built into the pricing tiers rather than automatically applied to your account. This transparent approach to pricing makes PostHog particularly appealing for startups and growing teams who want predictable cost structures.

PostHog Free Tier: What’s Actually Included
PostHog’s free plan offers a genuinely functional analytics platform without requiring a credit card. The Free tier is one of the most generous in the product analytics space, making it ideal for early-stage teams and developers exploring product analytics solutions.
Free Tier Features
- 1 million events per month for Product Analytics
- Unlimited team members (unlike Mixpanel’s single-user limitation)
- 7-day data retention (events older than 7 days are automatically deleted)
- 50 session recordings per month (stored for 1 day only)
- Unlimited feature flags (though you’ll pay separately if upgrading to paid)
- Basic dashboards and reporting capabilities
- API access for integrations
- Community support through forums and documentation
Free Tier Limitations
The 7-day event retention is the most significant constraint. You cannot build historical trend analysis or review data from previous months, which limits your ability to conduct long-term cohort analysis or seasonal comparisons. Session replay functions essentially as a demo—50 recordings monthly isn’t sufficient for meaningful user behavior debugging or comprehensive support workflows.
Additionally, the free tier lacks advanced features such as correlation analysis, group analytics, and advanced filtering capabilities that become available in paid plans. For teams serious about data-driven decision making, these limitations typically necessitate an upgrade within the first few months.
Best for: Pre-launch startups, open-source projects, hobby applications, and teams piloting PostHog alongside existing analytics tools before committing to a paid plan. It’s also excellent for developers building side projects or small internal tools that don’t require extensive historical data.

PostHog Paid Tiers: How Usage-Based Billing Works
PostHog uses a consumption-based billing model where costs scale directly with your usage across each product. Unlike tiered subscription plans with fixed monthly fees, you’re charged based on the volume of events, recordings, or requests you generate each month.
Understanding Volume-Based Pricing
Each PostHog product has its own pricing structure with volume discounts that automatically apply as your usage increases:
| Product | Free Allowance | Paid Pricing Structure |
|---|---|---|
| Product Analytics | 1M events/month | $0.00045/event (volume discounts apply) |
| Session Replay | 5,000 recordings/month | $0.005/recording (decreases with volume) |
| Feature Flags | 1M requests/month | $0.0001/request (scales down at higher tiers) |
| A/B Testing | 1M requests/month | $0.0001/request |
| Surveys | 250 responses/month | $0.20/response |
Key Advantages of Usage-Based Pricing
PostHog’s billing model offers several benefits for growing companies:
- No waste on unused features: You’re not locked into paying for products you don’t actively use
- Predictable scaling: Costs grow proportionally with your actual product usage and customer base
- Generous free tiers: Each product includes substantial free allowances that reset monthly
- Transparent pricing: No hidden fees or surprise charges—usage is tracked in real-time
- Flexible adoption: Start with one product and add others as your analytics needs evolve
Cost Management Strategies
To optimize your PostHog spending, consider implementing these strategies:
- Event filtering: Only track essential user actions to reduce event volume
- Sampling for session replay: Record a percentage of sessions rather than all user interactions
- Conditional feature flags: Use targeting rules to minimize unnecessary flag evaluations
- Usage monitoring: Set up billing alerts to track consumption patterns and avoid unexpected charges
- Data retention policies: Adjust retention periods based on actual analysis needs
For teams evaluating whether PostHog’s pricing model fits their budget and requirements, exploring PostHog alternatives can provide valuable context on how other platforms structure their pricing and what trade-offs exist between different analytics solutions.
Who Should Choose PostHog’s Pricing Model?
PostHog’s usage-based pricing is particularly well-suited for:
- Early-stage startups: Generous free tiers allow you to start without upfront costs
- Product-led growth companies: Pay-as-you-grow aligns costs with revenue expansion
- Engineering-focused teams: Developers appreciate the transparent, predictable pricing structure
- Companies with seasonal traffic: Costs naturally decrease during slower periods
- Privacy-conscious organizations: Self-hosting options provide complete data control (additional infrastructure costs apply)
However, companies with very high event volumes or those requiring enterprise-grade support and SLAs should carefully calculate potential costs, as usage-based billing can become expensive at scale. In these scenarios, consulting our 2026 analytics pricing guide can help determine whether PostHog or a competitor offers better value for your specific usage patterns.
