About this tool
Parse a Compose YAML file and check basic service structure locally. Processing happens locally in your browser, so your input is not sent to a server or included in analytics.
Frequently asked questions
Does this fully validate the Compose specification?
No. It checks YAML syntax and a few basic structure rules, not every Compose field or runtime behavior.
Does it start containers?
No. The file is parsed only in your browser.
