In-depth Review: Pricing Models

PostHog uses a usage-based pricing model, charging separately for each product in its suite:

  • Product analytics: charged per event
  • Session replay: charged per session
  • Feature flags and A/B testing: charged per request
  • Surveys: charged per response

PostHog offers a generous free tier every month, which gives access to most features but limits the number of projects and users. Yet, as you capture more data and use more features, your costs increase, making it complex to predict the total cost as you scale.

OpenReplay’s pricing model, on the other hand, is simple and all-inclusive. Every plan provides access to all features with unlimited users and projects.

For the dedicated cloud offering, the pricing is not based on volume. Instead, you only pay for the VM capacity needed to capture your traffic and keep the data as long as you wish.

This dedicated cloud solution is unique in the session replay market. It includes:

  • No limits on recordings and data retention
  • All features included: Every feature is available without additional charges.
  • Predictable pricing: No complex calculations based on events, sessions, or features.

The dedicated plan ensures data security and compliance, with scalable options for processing power and memory to suit your needs. You can deploy in any region, ensuring compliance with regional regulations. This makes OpenReplay’s pricing straightforward and easy to understand, providing a clear and predictable cost structure.
