Why use Parsy as your YAML viewer?

YAML's readability depends entirely on indentation, which makes long Kubernetes manifests or CI pipelines hard to scan in a plain text editor. Parsy acts as a YAML formatter and viewer that turns indentation into a real, collapsible tree directly in your browser tab.

Keys, strings, numbers, and booleans are syntax-highlighted, nested mappings and sequences collapse independently, and Ctrl+F search jumps straight to the key you're looking for.

Frequently asked questions

Does Parsy render Kubernetes and Docker YAML?

Yes. Parsy works with any standard YAML document, including Kubernetes manifests, docker-compose.yml, and CI/CD pipeline files.

Does Parsy validate YAML syntax?

Parsy is a formatter and viewer focused on readability, not a strict schema validator. Well-formed YAML renders as a tree; malformed indentation may not parse as expected.

Are anchors (&) and aliases (*) supported?

Parsy displays anchors and aliases as written in the source. It does not resolve or merge them into the final dereferenced value.

Is my YAML data uploaded anywhere?

No. Parsing and rendering happen 100% locally — nothing is sent to a server.

Can I view a local .yaml or .yml file?

Yes. Open the Parsy web app or the extension's File Viewer and drag your file in, or use 'Browse Files' to select it.
