About this YAML highlighter
This tool color codes YAML, also known as Yet Another Markup Language, so configuration files and structured data are easier to inspect. It is useful for Docker Compose files, Kubernetes manifests, CI/CD pipelines, app settings, documentation snippets and API examples. There are no downloads or signups, and highlighting updates as you type.
Is my YAML uploaded?
No. The highlighter runs locally in your browser and does not submit pasted YAML to devbruh servers.
Can this validate YAML?
This page focuses on readable syntax highlighting. Use a YAML parser or validator when you need strict validation.
