YAML Linter Lite
Catch common YAML indentation and key spacing mistakes locally.
Catch common YAML mistakes
YAML is whitespace-sensitive, so a stray tab, inconsistent indentation, or a missing space after a colon breaks the file in ways that are hard to spot. This lite linter flags those common mistakes so you can fix them before a tool rejects the config.
Catching indentation and key-spacing issues early saves the frustrating cycle of a pipeline failing on a malformed config. Paste your YAML, review the flagged issues, and correct them — all locally, so your config never leaves your browser.
Catching YAML slips
It flags tabs, inconsistent indentation, and a missing space after a colon — the usual silent breakers. Linting runs in your browser and never uploads your file.
