Tired of wasting 20 minutes on failed builds?
Every Expo/RN developer knows the pain: push code, wait for EAS Build, watch it fail after 15-20 minutes because of a config mismatch you could have caught locally.
Wasted Build Minutes
EAS builds take 10-25 minutes. A failed build means you wait again after fixing. That's 30+ minutes wasted on something catchable.
Hidden Config Issues
Mismatched SDK versions, wrong native module configs, missing env vars — these only surface during the build.
"Works Locally"
The classic. It builds fine on your machine but fails in CI because of subtle environment differences.
Three commands. Zero wasted builds.
Run before every build. Integrate into CI. Catch problems early.
Check

"The monorepo support alone is worth it. No more guessing why the build fails in CI but works locally."
Sarah Kim
Lead Developer at AppStudio
"We added it to our CI pipeline as a pre-build step. Build failure rate dropped by 60%."
