Best for / Not for

BEST FOR

  • Product teams that want analytics and qualitative behavior signals together
  • Applications that need feature flags beside event data
  • Teams willing to govern event identity and volume

NOT FOR

  • Teams that only need a minimal page-view counter
  • Products that cannot define an event taxonomy
  • Applications that cannot send behavioral data to the selected deployment

Where it fits in your stack

Connects frontend and backend events to analytics, session replay, feature flags, surveys, and experiments. It can replace separate analytics, replay, and feature-flag services, but not the application's primary database.

Pricing

Pricing model: Free and Pay-as-you-go. Base fee is $0.

Free allowance: 1M analytics events, 5,000 session recordings, 1M feature flag requests, and 1,500 survey responses per month. The Free plan includes 1 project and 1 year of data retention. Usage stops at the free limit — no surprise bill.

Overage rule: identified event $0.000198 · anonymous event $0.00005 (after 1M). Group analytics add-on $0.000071/identified event. Each product has a separate meter.

Trade-offs

  • Identified events cost roughly 4x anonymous events. Most events from a SaaS tracking paying users are identified, which is why cost estimates based on the headline rate usually come out low.
  • Combining several product tools can increase implementation scope
  • Retention and billing differ by product inside the platform
