Trust center Why patching is more secure What Shorebird collects
We never see your source code
Only compiled builds (release archives and patches) and the metadata to deliver them reach us.
Nothing about who your users are
Your app sends only what delivering patches and counting active installs needs: no names, accounts, device identifiers or location.
Your app runs only your patches
New releases are signed by default, so your app runs only patches signed for it. Bring your own key if you prefer.
Ready for larger teams
SAML single sign-on, audit logs and invoice billing.

Common questions

Eric Seidel

Built by the people who made Flutter

Shorebird was founded in 2023 by Eric Seidel, the creator of Flutter, and is backed by Accel.

About the team
How does Shorebird relate to Flutter?

Shorebird is a fork of Flutter that adds Code Push: it replaces the Flutter engine, not Flutter, so you keep the Flutter tooling you already use.

Is Code Push allowed by the App Store and Google Play?

Yes. Code Push works within App Store and Google Play guidelines: your app's native shell goes through normal store review, and patches must not change the app's primary purpose (Apple Developer Program License Agreement section 3.3.1(B)). See the store compliance FAQ.

What can a patch change?

Any Dart code: fix a bug, add or remove a Dart package, point at a different backend. Native code and assets are out of reach, so changes to build files like build.gradle or Podfile, a plugin's native code, app permissions, or images and fonts in pubspec.yaml need a new store release. The CLI warns you if it detects native or asset changes when you patch.

How do patches reach my users?

Your app checks for a patch when it launches, then downloads and installs it in the background without interrupting the user. It takes effect on the next launch. If a patch ever fails to load on a device, the app falls back to the last version that worked.

Which platforms are supported?

Android, iOS, macOS, Windows and Linux. Adding Shorebird requires no changes to your app code.

Can I self-host Shorebird?

No. Shorebird has no plans to offer on-prem, self-hosted or cloud-prem versions. We are happy to talk through how the hosted service can meet your requirements.
