PostHog is an all-in-one product platform with analytics, session replay, feature flags, experiments, surveys, error tracking and a data warehouse. Every product has a free monthly allowance, and beyond that you pay only for usage with billing limits per product.
Key features
- Product and web analytics, 1M events a month free
- Session replay, 5,000 recordings a month free
- Feature flags (1M requests free) and experiments
- Surveys and error tracking
- Data warehouse and data pipelines
- Unlimited team members on every plan

What stands out
- Free tier with no credit card that renews monthly, not a trial
- Usage stops at the free limits, so no surprise bills
- Unlimited team members
Trade-offs
- The free plan has 1 project and 1-year data retention
- Pay-as-you-go has no flat price, so cost depends on usage across products
- Platform packages (SSO, audit logs, custom roles) are sold separately
