  Hardware Access

Make use of hardware features on mobile devices in a platform-agnostic way. Gluon Charm Down makes available all the storage systems, accelerometers, screen details, GPS devices, and more in a device-independent fashion

  Open Source & Community

Gluon Charm Down is yet another Gluon open source project available in our gluon-oss BitBucket repo. It is freely licensed under the GPL license, and external contributions are very welcome.

  Commercially Supported

As with all Gluon open source projects, Gluon offers commercial support in a variety of ways.

Gluon can provide custom consultancy and training, commercial licenses, and finally open source commercial support.


Gluon Mobile

Gluon Charm Down ships as part of Gluon Mobile, providing you with a single solution for building cross-device applications with a singel code base, and not one line of platform specific code. Of course, you can also use Gluon Charm Down in your own projects without Gluon Mobile – just grab the source code from our repo, or add a dependency to your build script.

 


Getting Started

Gluon Charm Down is free and open source (it’s GPL licensed) – you can grab the latest code from our gluon-oss BitBucket repo. We also provide releases to our open source commercial support customers on a regular cadence (daily or monthly), and we provide free samples to kickstart your development.
