FAQ
Does the viewer detect indentation errors and tab usage?
Yes. Because YAML requires strict whitespace indentation, the validator immediately highlights misalignment and illegal tab characters.
Can I collapse large sections of Kubernetes manifests?
Yes. The interactive tree allows expanding and collapsing individual sections as well as expanding/collapsing the entire document.
Is my YAML manifest content saved on any remote system?
No. Visual tree rendering is executed strictly inside your local browser runtime without sending payloads over the network.
