PostHog

- 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
VWO
- Unlimited experiments, variations and metrics from the entry plan
- Part of a wider platform with behavior analytics and personalization
- Self hosting and an approval workflow on Enterprise
Trade-offs
