YAML Tools

Version 3.0 is the biggest update yet, bringing schema validation, a redesigned file workflow, and a faster, more polished editor. • JSON Schema Validation: Validate YAML against JSON Schema right inside the app. Pick a schema once and it stays attached to your file with live error reporting. • Open YAML files directly from anywhere: Tap any .yaml or .yml file in Mail, Files, Safari, or other apps to open it instantly in YAML Tools. Explore, format, and transform your YAML without extra steps. • Recent Files: A new jump-list sheet remembers the last files you opened. Tap to reopen, even files stored outside the app on iOS. • Native iOS Document Picker: All-new native file open/save experience with proper security-scoped bookmarks, so files from iCloud Drive, the Files app, and external providers just work. • Redesigned Action Toolbars: Grouped floating action clusters on every screen for cleaner reachability and a more focused workspace. • Sharper Code Editor: JetBrains Mono for code, refined line numbers, a streamlined keyboard toolbar, and a cleaner syntax highlighter across all formats. • Polished iOS Theme: Refreshed light and dark themes with better contrast, smoother surfaces, and tighter visual rhythm. • Performance: Schema validation runs off the main thread, so larger files validate without freezing the UI.

Multi-Tab Support: Work with multiple YAML files simultaneously without switching windows. Open and edit files side by side in dedicated tabs, keeping your workflow smooth and organized. Direct File Access: Open YAML files directly from your device storage or file manager. No more import/export. Refreshed UI: A cleaner, more intuitive interface that gets out of your way. Improved layout, better readability, and a polished look.
