Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Statsig

  • Pro plan is limited to a single project, requiring Enterprise for multi-project support.
  • Overage pricing on the Pro plan can become costly for high-event-volume products.
  • Warehouse-native deployment and advanced access controls are gated behind custom Enterprise contracts.
  • Free tier session replay and analytics retention are capped, pushing active teams toward paid tiers quickly.

LaunchDarkly

  • Pricing scales rapidly with monthly active users, becoming expensive at scale
  • Limited seats for engineers on standard plans, forcing upgrade to enterprise
  • Advanced features like experimentation and audit logs require higher-tier plans
  • Occasional reliability issues and backend delays reported by users
