Greymatter.io keeps a full history of your settings in Git. Your team restores the last working version in Git. Greymatter.io applies the restored version automatically, so apps stay online.

Yes. Greymatter.io works with Argo CD, Flux, and your existing Git repositories. Greymatter.io layers onto the infrastructure you already run, with no rip and replace.
