The core software is free to use. We will eventually charge for premium features, like Discord does with Nitro. The streaming software and core functionality will remain free, and we will use that to sell premium versions of Parsec.
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.
If you're a game developer looking to add online co-play to your game via the Parsec API, reach out here.
