iPhone
Yamlite checks your YAML the moment you paste it — and now explains and fixes it too. 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 comes with its exact line and column, a plain-language explanation, and — for most errors — a one-tap fix. Load a built-in sample to see it in action, or paste your own file.
• Instant, offline validation as you type
• Clear errors with line and column numbers
• One-tap fixes for tabs, quotes, brackets, duplicate keys, and indentation
• Plain-language explanations for every error, fully offline
• History of your validated documents, one tap to reload
• 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):
• Fix All — repair every fixable issue in one tap
• AI explanations tailored to your exact line (Apple Intelligence, on-device)
• Structure outline with type badges

New: one-tap quick fixes for individual issues, Fix All, JSON ↔ YAML conversion, AI-powered error explanations with Apple Intelligence, and a history of your validated documents. Pro is still one one-time purchase.
