Summary
Hi everyone, today I’m releasing CT_DevModeManager (DMM). This plugin was built to bring something RPG Maker MZ has always lacked: A proper in-game developer UI. Instead of relying on menus, plugin lists, or external tools, DMM introduces a developer dashboard that runs directly inside the game engine.

Hi everyone, today I’m releasing CT_DevModeManager (DMM).
This plugin was built to bring something RPG Maker MZ has always lacked:
A proper in-game developer UI.
Instead of relying on menus, plugin lists, or external tools, DMM introduces a developer dashboard that runs directly inside the game engine.
The goal is simple:
Give developers a clean UI and editor-style tools inside RPG Maker itself.
Developer Dashboard
DMM adds a full Developer Dashboard overlay that can be opened in-game with a hotkey.
It features:
• A 3×5 plugin grid interface • Mouse and keyboard navigation • Instant access to plugin tools and editors • Search, sorting, and favorites
This makes managing large plugin stacks far easier than scrolling through the default Plugin Manager.
Built-in Plugin Inspectors
DMM also includes two built-in viewers:
Plugin Help Viewer
• Displays plugin documentation directly inside the game • Adjustable font sizes for readability • Fullscreen overlay interface
Plugin Parameters Viewer
• Clean read-only view of plugin parameters • Sensitive fields (like passwords) are automatically masked • No risk of accidentally changing values
These viewers allow developers to inspect plugins without leaving the running game.
Designed for Editor Tools
DMM also acts as a tool hub.
Plugins can register their own editors or utilities into the dashboard. Once registered, they appear as clickable tools inside DMM.
This allows developers to build things like:
• visual editors • debugging tools • data tools • configuration panels
All accessible directly from inside the game.
Why This Exists
RPG Maker has always been powerful, but its development UI is limited.
Many systems require editing JSON files, plugin parameters, or external tools.
DMM moves development closer to how modern engines work:
Tools inside the engine.
The First Piece of a Bigger Ecosystem
CT_DevModeManager is the foundation for future developer tools in the Cynthia Tools ecosystem.
More plugins will integrate directly with DMM, turning it into a central hub for development tools inside RPG Maker MZ.
You can download it for free at CT_DevModeManager
