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.
Private and instant
Everything runs locally in your browser using standard web APIs — nothing is uploaded, logged, or stored on any server — so the tool works offline, responds instantly, and keeps whatever you paste in on your own device. That makes it safe to use even for confidential, client, or internal data you would never send to an unknown website.
