The short version

  • Only Expo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Emerge Tools the value is proportional to application size and team size, so a small app learns what is wrong once and then pays a recurring subscription for a number that barely moves.; Expo free tier build counts and MAU support are low, pushing active projects to paid plans quickly.
  • They diverge on capability: Emerge Tools covers Size diff on pull requests, Expo covers Expo SDK.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Emerge Tools

  • The value is proportional to application size and team size, so a small app learns what is wrong once and then pays a recurring subscription for a number that barely moves.
  • Dead code detection depends on shipping instrumentation into production builds to observe which code real users execute, which several organisations refuse on privacy or performance grounds.
  • Pricing is quoted per application, so companies with a portfolio of apps face a multiplied cost that is difficult to justify outside the flagship product.
  • Uploading release binaries to a third party is a supply chain and confidentiality question that security review will raise, and it delays procurement more than the price does.
  • It measures and reports but does not fix anything, so the subscription only pays back if the team has capacity to act on the findings, which is exactly the capacity such teams tend to lack.

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.

Answered from the vendors’ own pages

Emerge Tools: Does app size really affect installs?

Yes, measurably on Android and in markets with constrained data. The size of the effect depends on your audience, which is why per app measurement is the point.

Expo: What does Expo cost?

Expo offers a free plan, a Starter plan at $19/month with $45 build credit, a Production plan at $199/month with $225 build credit, and custom Enterprise pricing.

Emerge Tools: Do we have to upload our binary?

Yes, analysis runs on the build artefact. Expect a security review before procurement completes.

Expo: Is there a free plan, and what are its limits?

The Free plan includes 15 Android and 15 iOS builds, low-priority build queue access, 60 minutes of CI/CD workflows, and support for 1,000 monthly active users on updates.

Source
Emerge Tools: Is this a replacement for crash reporting?

No. It covers size, launch performance and snapshots. Crash and error monitoring is a separate purchase.

Expo: How is usage metered on paid plans?

Beyond included build credit, Expo charges per build by platform and worker size, per CI/CD workflow minute, per million Observe events, and graduated per-MAU overage rates for updates.
