Catch YAML errors before they break your deploy
YAMLValidator runs a deterministic lint ruleset (tabs, indentation, duplicate keys, anchors/aliases, quoting, schema keywords) against your config, then a model-assisted pass explains each issue with the exact line and a corrected snippet. Built for CI and config reviews — never executes your code. It starts at $9/month.
