Docker Compose Validator LOCAL ONLY

Parse a Compose YAML file, inventory services, and flag common structural, dependency, port, and operational issues before you run it.

Compose YAML

Paste compose.yaml or docker-compose.yml. Parsing and checks run locally in the browser.

This is a local structural linter. It does not pull images, inspect your Docker daemon, resolve environment variables, or execute Compose.

Catch the obvious issues before a deployment window

The linter checks the services shape, service names, image/build presence, port mappings, duplicate host ports, dependencies, named volumes, and a few scaling/security footguns. Review final compatibility against your installed Docker Compose version.
