Cloud builds for websites and Android source

Build an Android app.
From the project you have.

Bring a live website or a Flutter / native Android project. Configure the app, follow the build, and download the result.

Website → app

I have a website

Start with a marked Android Preview. Purchase an App license when you are ready for a release.

1 marked Preview APK. No card required. Preview does not include source compilation.

Source → APK

I have source code

Compile a Flutter or native Android project. Builder or Pro is required before uploading a ZIP.

  • Flutter or native Android project
  • Source ZIP or accessible Git repository
  • Builder or Pro · compiles use included credits

Need another platform? Website apps for iOS and Windows are paid workflows. IPA delivery is unsigned by default.

Before you build

Know what you will receive.

Compilation, installation and store review are different steps. The build result tells you what was produced; you still test your app.

Website Preview

A marked Android APK

Your website in our Android WebView shell. Install it on a device to check navigation, sign-in and content.

Since September 30, 2026, certified Android devices in Brazil, Indonesia, Singapore and Thailand install apps from Google Play and six other stores only if a verified developer registered them; Google registers eligible Google Play apps automatically. Google says APKs people install directly are not affected yet, and plans to extend verification to them in 2027. Preview APKs and website apps signed with our shared platform key can't be registered. What this means

Try your own website

Android source

Your compiled project

Build a supported Flutter or native Android project. Review the log, artifact and signing details before distribution.

Read build requirements

Website IPA

Build first. Then sign.

Unsigned by default. Optional cloud signing needs an active Pro plan and matching Apple credentials. Signing does not guarantee store approval.

Engineering case study · July 2026

An archived Flutter project.
A toolchain mismatch.

Our published investigation follows flutter/gallery from a dependency failure to a compatible Flutter toolchain. It includes the first diagnosis, why it was wrong, and the log excerpts that changed it.

Historical build record, not a live build or a promise that every uploaded project will compile.

Error: 'UnmodifiableUint8ListView' isn't a type.
Target kernel_snapshot failed: Exception

Choose by what you are building

One website, or ongoing builds?

An App license belongs to one website. Builder and Pro are account subscriptions. A website license does not unlock source compilation.
