The short version

  • Only Expo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Expo free tier build counts and MAU support are low, pushing active projects to paid plans quickly.; WarpBuild per-minute pricing requires tracking usage to estimate monthly costs
  • They diverge on capability: Expo covers Expo SDK, WarpBuild covers Optimized runner infrastructure.
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

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

Expo

  • Free tier build counts and MAU support are low, pushing active projects to paid plans quickly.
  • Usage-based overage charges for builds, CI/CD minutes, and MAUs can make costs less predictable.
  • Concurrent build limits on lower tiers slow down teams with frequent releases.
  • Some native functionality still requires ejecting to bare workflow or writing custom native modules.

WarpBuild

  • Per-minute pricing requires tracking usage to estimate monthly costs
  • Large configuration runners (32 vCPU) expensive at $0.064/min
  • macOS M4 Pro 12-core at $0.16/min is highest-cost option
  • BYOC option requires cloud setup by customer
