You can try out Chaquopy right now for free by cloning one of the example apps, or following the setup instructions in an app of your own.
The unlicensed SDK is fully-functional, but apps built with it will display a notification on startup, and are limited to a run-time of 5 minutes. To remove these restrictions, a license is required. All licenses are perpetual and royalty-free, and include upgrades to all future versions of the SDK.
Commercial license
A commercial license allows Chaquopy to be used in closed-source apps. Please contact us to request a license key, giving the following information:
- How many developers on your project will be using Chaquopy.
Open-source license
For open-source apps, Chaquopy will always be free of charge. Here’s how to qualify:
- Release your app’s source code on a public website such as GitHub. The app doesn’t need to be finished, but it does need to already be using Chaquopy in a non-trivial way.
- Include a notice releasing the code under an open-source license. If you haven’t already chosen one, we recommend the MIT License.
Once you’ve done that, please contact us to request a license key, giving the following information:
- Where the app’s source code is available.
- The application ID from your
build.gradlefile. This should be something unique to yourself, not a generic value likecom.example.myapplicationorcom.chaquo.python.console.
You must keep the published source code up to date for as long as you use the free license key.
Activating a license
Once you have a license key, activate it by adding the following line to the project’s local.properties file:
chaquopy.license=<license key>
The notification and time limit will then be removed the next time you build your app.
