Yamlite checks your YAML the moment you paste it — no accounts, no servers, everything runs on your iPhone. Whether you're editing a Docker Compose file, a GitHub Actions workflow, or a Kubernetes manifest, Yamlite catches the mistakes that break your build: tab indentation, inconsistent spacing, duplicate keys, unclosed quotes, and malformed flow collections.
Every issue is reported with its exact line and column, so you can jump straight to the fix. Load a built-in sample to see it in action, or paste your own file.
Pro unlocks a structure outline that shows how your document parsed into a typed tree, plus one-tap export of a full validation report.
• Instant, offline validation as you type
• Clear errors with line and column numbers
• Handles mappings, sequences, flow style, comments, and multi-document files
• Built-in samples: Docker Compose, GitHub Actions, Kubernetes, app config
• No tracking, no network, no sign-in
Yamlite Pro (one-time purchase):
• Structure outline with type badges
• Export and share validation reports
