When we work on a project with a client, we provide the base Glamkit software for free; we only charge for customisations and additions. We provide everything we do under a perpetual, royalty-free license to our clients. You always have the source and right to do anything you want with it except sell it or give it away to someone else. If you use it, it’s effectively open source.
But, for the moment, we’re not going to release Glamkit as a public, open-source project. You only get the benefits of open source if there is a community of people working with the software. Otherwise, open source is a cost, not a benefit.
We're definitely enthusiastic users of and contributors to open source projects. We're not closing off the idea that Glamkit might one day become an open-source project again. But for the moment, this arrangement supports our vision and our clients best.
