Ask HN: Best rollout tool for complex multi region K8 deployments?

Our team has been looking at Spinnaker for a while now (as well as Spinnaker vendors) but we are disappointed with the large number of bugs in the Spinnaker ecosystem. Every time we upgrade, 2 other things that worked before break. What other tools are out there we should be looking at? We want things like:

- pipelines as code - canarying - automatic canary analysis - automatic rollback - blue/green, progressive rollouts, other rollout strategies - approval gates - integration with Vault, Okta
