The core software is free to use. We offer a way to support the Parsec Software through our Warp Package. You can learn more about Warp here. To be clear, the streaming software and core functionality will remain free. We will not compromise the quality of the stream or hide features that are important to a great experience with Parsec. We set out to build the best game streaming software in the world, and we will not compromise that by blocking your access to that streaming functionality. Warp will come with badges, early access to features, and themes among other things.
In addition to that, on a very limited basis, we license an SDK version of Parsec to companies looking to incorporate low latency streaming into their software. If you're interested in the SDK, please email us here.
