Today we released Variable Sets Public Beta on Terraform Cloud for everyone, including those on the Free tier! 
Variable sets provide an excellent way for practitioners to create and apply a set of variables to 1. all workspaces under the same organization or 2. one to many workspaces under an organization.
As part of the Public Beta release, we also shipped the API support, so you can optionally use them to customize your infrastructure management process. We plan to add TFE provider support soon!
If you want to learn more about this feature, here are some tutorials to guide you through setting up variable sets, and here is our official documentation. Meanwhile, we’d love to hear your feedback!

Thanks so much for your continued support. We really, really appreciate it!
