App Support.

We're here to help.

Community Contributions

We occasionally get asked whether we support other Open Source projects and the technology community in general. We're proud to say that we do: SparkLabs make a variety of contributions to Open Source projects in many different categories.

As well as releasing open source projects of our own, we also contribute source code and knowledge to a number of other projects. Below is a list of some of the contributions we have made. Please note that this is a non-exhaustive list: you'll find further discussion and changes in project mailing lists and bug/issue tracking systems.

SparkLabs GitHub

On our GitHub page you can find a variety of projects, tools and examples we make available, as well as many different forks for projects we are actively participating in. In particular:

SparkLabs Launchpad PPA

We maintain a Launchpad Personal Package Archive for Open Source projects we make modifications to while awaiting the upstream maintainers to accept patches. Our Launchpad PPA currently contains a modified version of OpenVPN to be used as a server with U2F support.
