EAS Update vs BetterCodePush: which one fits how you actually build?
Both ship JavaScript over the air. The real difference is what they assume about your project: fully managed Expo on one side, bare React Native and prebuild on the other.
We get asked this several times a week, and the answer is less adversarial than comparison posts usually are: EAS Update and BetterCodePush mostly serve different teams, and the deciding factor is not features — it's how your project is structured and who you want holding which parts of your stack.
The one-sentence versions
EAS Update is the update pillar of Expo's platform: expo-updates in the app, EAS servers behind it, tightly integrated with EAS Build, runtime-version fingerprinting, and the rest of the Expo workflow. BetterCodePush is a single-purpose update channel for bare React Native and Expo prebuild apps: it owns the native bundle-loading path and provides hosted CDN delivery, but deliberately does not bundle a build service or a wider workflow product around it.
Where EAS Update is the right answer
If you are all-in on managed Expo, stop reading and use EAS Update. The integration depth is real: fingerprint-based runtime versions catch native/JS incompatibilities automatically, updates plug into EAS Workflows, and SDK 55 introduced opt-in Hermes bytecode diffing that can materially reduce update downloads. Splitting your update infrastructure away from the platform that manages everything else about your app buys you nothing.
Where the fit gets awkward
The interesting cases are teams who left — or never entered — the managed workflow:
- Bare React Native apps.
expo-updatescan be installed in bare projects, but you are wiring a platform component into a project that shares none of the platform's other assumptions, and you inherit the runtime-version model whether or not it fits your release process. - Prebuild/CNG apps with heavy native customization. You chose prebuild to control the native side. The more you customize, the more you manage compatibility between your native reality and the managed tooling's expectations.
- Teams that just want an update channel. Some teams have CI, builds, and release process solved, and want exactly one thing: deliver signed bundles to matching binaries with staged rollouts and a kill switch. A platform is overhead for them, not leverage.
That last profile is who we built for. One native build to install the update runtime, then deploy, stage, expand, or disable — your build service, CI, and native projects stay untouched.
Pricing shapes behavior
EAS Update bills for monthly active users and global edge bandwidth. The MAU portion grows with your audience, while each additional update can also increase bandwidth use; check Expo's current pricing before modelling a decision. Whether that is good for you depends entirely on your ratio of users, release cadence, and update size — we walk through the arithmetic in what OTA updates actually cost at scale. BetterCodePush is free during the beta, and our bias is toward pricing that doesn't penalize having users.
A fair scorecard
- Managed Expo integration: EAS Update, decisively.
- Bare RN and heavily customized prebuild: BetterCodePush — it's the entire design target.
- Compatibility safety: different philosophies — EAS fingerprints your native runtime; BetterCodePush pins updates to explicit target app versions. Fingerprinting automates more; explicit targeting is easier to reason about when something goes wrong.
- Rollouts and rollback: both do staged percentages and reverts; table stakes in 2026.
- Surface area: EAS is a platform with an update service; BetterCodePush is an update service, full stop.
If you're still deciding what kind of project you are, the boundary between the workflows — and why the in-between cases fall through the cracks — is the subject of OTA for Expo prebuild and bare React Native.
