Open Beta

The Fermyon Cloud is currently an open beta service. This means that Fermyon Technologies does not provide any service-level agreements on the service, including the workloads you choose to deploy. We also reserve the right to break compatibility with:

  • Support for previous and current versions of the Spin SDK
