VyOS started as a community project, and retains that spirit. The entire code base is open for contributions. Even if you are not a programmer, there’s a lot of things to do: writing documentation, answering questions on the forum, testing rolling release images and reporting bugs.
Starting from VyOS 1.2.0, only rolling release builds are available publicly, while LTS releases are only available to subscribers. However, it doesn’t only mean commercial customers! Every active contributor is eligible for a subscription too. We are doing hard work maintaining LTS releases, and we are ready to share the results of that work with everyone who helps us move the project forward, whether they contribute to the project financially by purchasing a subscription, write code, write documentation, actively test VyOS and make good bug reports, or spread the word.
