The first comprehensive VS Code extension built specifically for RPG Maker MZ plugin developers. 14 free features + 14 Pro features covering annotation intelligence, testplay debugging, conflict detection, and more.
Stop writing MZ plugins like it's 2010. Get syntax highlighting, validation, IntelliSense, and a full debugging workflow — all purpose-built for MZ's plugin annotation system.
RPG Maker MZ plugin development has had almost zero dedicated tooling. Existing extensions are either abandoned, MV-only, or provide just snippets. This extension gives you a complete development environment:
- Write faster — annotation completion, @type suggestions, plugin templates
- Catch bugs early — real-time validation, conflict detection, asset checking
- Debug without pain — one-click debugger setup, variable editing, live game preview
- Understand your project — dependency graph, class hierarchy, database browser
