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

Yarn

  • Yarn 2+ (Berry) has limited ESM support which can be a constraint for some projects
  • Smaller ecosystem and community compared to npm, though still substantial
