Read, diff and apply Kubernetes YAML
Every resource shows its live YAML, cleaned of noise. Compare it against the last-applied configuration with a colour diff, paste a manifest to apply, and see exactly what will change before it does.
Works with Google GKE, Amazon EKS, Azure AKS, DigitalOcean, self-managed & more · macOS Sonoma (14) or later
Manifests you can actually trust
Live, readable YAML
See any resource's current manifest with managed-fields noise stripped out, so you read what matters instead of scrolling through server clutter.
Diff against last-applied
A line-numbered, colour-coded diff shows exactly how the live object drifted from its last-applied configuration - additions, removals and changes at a glance.
Apply a manifest
Paste or edit YAML and apply it to the cluster, with a dry-run-style preview of what the change will do before you commit.
Secrets stay protected
For Secrets, values in the YAML are redacted behind the same Touch ID gate as the rest of the app - you don't leak data just by opening a manifest.
Export any manifest
Save a resource's YAML to disk in a click for a review, a backup, or to check into git.
Always the live object
The YAML is fetched live from the API, so what you diff and apply reflects the real state of the cluster, not a stale cache.

Questions, answered
Can I edit and apply YAML, or only view it?
Both. Every resource shows its live YAML for reading and diffing; applying a pasted or edited manifest is part of Kubius Pro, with a preview of the change before it's committed.
How does the diff work?
Kubius compares the live object against its last-applied configuration and renders a line-numbered, colour-coded diff, so drift is obvious. The diff appears whenever a last-applied annotation is present.
Is it safe to open Secret YAML?
Yes - Secret values in the YAML are redacted and gated behind Touch ID, the same as the Data view, so opening a manifest never exposes the raw data.
Which parts are Standard vs Pro?
Viewing live YAML and the diff are available across tiers; applying manifests is part of Kubius Pro. The 14-day free trial includes everything.
