Before Vite+, we maintain Vite, Rolldown, Oxc, all of which are open source and widely used. These remain open source - nothing changes about existing projects.
Vite+ is an entirely new product built on top of our own open source, with additional features that are entirely new. You don't need to use Vite+. You can keep using all the open source that we already provide.
The revenue generated from Vite+ flows back into the development of both its proprietary features the underlying OSS. So if you are a user of our OSS, you'd benefit from Vite+ even if you don't use it, because it allows us to keep improving the OSS you are using.
