Expo

Build credits do NOT roll over month to month. If you include $45/month (Starter) or $225/month (Production) in build credits but ship less frequently one month, those credits are lost. This penalizes teams with irregular release cycles.

Bandwidth overage is $0.10 per GiB beyond your plan limit. A React Native app bundle is typically 20-50 MB. Pushing an OTA update to 10,000 users with a 30 MB bundle consumes 300 GiB, exceeding the Starter plan's 500 GiB limit in a single update cycle if done twice a month.

iOS builds are significantly more expensive in credits than Android builds because they require macOS build machines. A single iOS build on a large worker can consume $5-8 in credits. The $45 Starter credit allocation may only cover 5-8 iOS builds on large workers.

CI/CD concurrency is tightly limited

1 slot on Free/Starter, 2 on Production. Each additional concurrency costs $50/month. Teams running parallel builds for multiple platforms or branches need 3-4 slots, adding $50-100/month on top of the base price.

The free plan has a 45-minute build timeout. Complex apps with many native dependencies can exceed this, causing builds to fail. Starter and Production extend this to 2 hours, which effectively forces an upgrade for larger codebases.

Expo Hosting is included but limited

100K requests and 1M CPU-ms on all plans. Beyond that, requests cost $2 per million and CPU costs $0.04 per 1M CPU-ms. For server-rendered React Native web apps with meaningful traffic, hosting costs add up separately from the mobile-focused pricing.

Enterprise pricing is entirely opaque, no published starting price. Custom pricing with a minimum $1,000/month in build credits suggests a floor of $1,200-1,500/month for Enterprise, but you must go through sales to confirm.
