Felgo aims to improve your whole development process, from idea to app store. Today you get access to another piece of the puzzle. Introducing: Felgo Cloud Builds

Boost your Qt and Felgo app development with continuous integration and delivery for Qt and Felgo projects. As the only CI/CD exclusively for Felgo/Qt, it enables users to build and distribute apps with minimum effort and maximum speed.

Here is a short teaser video, introducing Felgo Cloud Builds:

Build your Apps in the Cloud with Felgo Cloud Builds

A great development workflow will make your good developers great, and your great developers exceptional. Deploying a new version to the app stores can be an annoying and time-consuming task. You need to make sure all your native tooling for each platform is set up and working as expected. And unfortunately, those tend to just break more often than you would like to.

Felgo already eliminates the need for native tooling while developing Qt/QML apps with Felgo Live code reloading. When it comes to store deployment, it was still required.

This changes with Felgo Cloud Builds. You connect your source code repository and we build the project for you, for iOS, Android and any other supported platform. Soon you will also be able to build for Windows, Mac, Linux, Embedded & Web (WebAssembly). Contact us if you need any of those platforms immediately.

You trigger a new build with a single button click and then you can:

  • Download the created binaries
  • Automatically upload them to your beta channels or the app stores
  • Try out previous versions of your application

Benefits of Using Cloud Builds

There are a number of benefits in using a CI/CD for developing your projects. First of all, the obvious one, time savings:

  • No setup of native frameworks required
  • Cut time to provide new test versions
  • Cut time for publishing new versions
  • Release more frequent updates for your users

The whole build and deployment process to both app stores only takes about 5-10 minutes.

Apart from that, there are several other advantages that you can benefit from:

  • Easy integration with Git
  • Automatic upload to iOS TestFlight and Google Play testing tracks
  • Deploy to iOS without the need for a Mac
  • Soon you will also be able to select different Felgo and Qt versions to build with

Why we built Felgo Cloud Builds for Continuous Integration and Delivery?

We built hundreds of projects using Qt on mobile platforms. Looking back at all the time spent on building and uploading binaries for every supported platform, we knew this had to change. With Felgo, we already made a lot of things simpler and faster during development, but manual publishing was still a major time-consuming process.

This is why now is the perfect time to use Felgo Cloud Builds. Cross-platform cloud building and publishing. Out of the box. Rapidly.

How to build apps with Felgo Cloud Builds

Your project is easy to set up. And after done once, there is no need to touch the configuration again, just build!

1. Create a new Project

Visit https://felgo.com/cloud-builds and create a new project.

First up are the general settings. You will also be able to choose different Qt and Felgo versions for your builds soon.

2. Connect your Git repository

In order to fetch your source code for building, you need to provide access to your Git repository.

For public repositories, this is the easiest, as you can just provide the HTTPS URL.

For private repositories, we recommend to generate a new SSH key pair. Then you can add the public key to your repository, and the private key to Cloud Builds (just as if it was your local development environment).

You can use GitHub, GitLab, Bitbucket, and custom private Git repositories.

3. Select target platforms and provide signing details

You can decide what platforms you want to build your application for.


Apple requires you to have an active App Store Connect account, in order to sign your application. To create a build that can be distributed and installed on your device, you need to provide your Certificate (*.p12 format) and Mobileprovision.

Please follow the Apple developer documentation if you are not familiar with how to obtain this information.


Android is less restrictive when it comes to signing and deployment. You can use the Development Build option to create test builds without providing any further information.

Make sure that your Android device allows installation of apps from unknown sources (not via Google Play Store), to install the development build directly on your device.

If you want to create a distribution build, signed with your own certificate, you need to provide your Keystore, together with the associated credentials.

Please follow the Android developer documentation if you are not familiar with how to obtain this information.

4. Configure app store uploads

Felgo Cloud Builds also allows you to upload your builds to the app stores. Then you can release them as test versions or publish updates for your users.


For iOS, it is required to provide the credentials of an App Store Connect user account. To guarantee the maximum access control for you, we recommend adding an own user to App Store Connect for Cloud Build access.


In order to fully configure an app in the Google Play Store, one manual APK upload is required. Before this, the App Identifier is not set within the Play Store, and the automatic uploads of Cloud Builds cannot be matched with the store app.

To enable app store uploads on Android, you need to provide the Google Play API JSON file of your Play Store account.

5. Build the project and grab a (quick) coffee

Now you are all set and can trigger a new build. This will only take about 5-10 minutes, depending on your configured platforms and if store deployment is enabled as well.

You can start a build using the “New Build” button. Then you can define the branch (or leave default) and enable deployment to app stores.

6. Download and Install Binaries

Once the build is finished you can download the binaries and test them on your devices. For iOS builds, the recommended procedure is to use automatic store deployment and to install the app using TestFlight.

7. Release Test Versions or Publish Updates

If store deployment is enabled, your new builds will appear in the configured stores. You can release them as new test versions or updates for your published apps.
