Where each one falls short

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

Buildkite

  • Free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention
  • Pro plan is $30 per active user per month, capped at 50 users, with only 10 of the up to 250 concurrent agents included before extra usage
  • Enterprise plan enforces a 30 user minimum even though pricing itself is custom
  • Hosted compute beyond included minutes is metered at $0.004 per vCPU minute on Linux and $0.02 per vCPU minute on Mac

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
