Metaviz is a free, web-based diagram tool that allows you to create and edit visual diagrams locally in your browser. It's compatible with Chrome, Opera, Edge, and Firefox. You can use it to write thoughts, design scenarios, or create custom nodes in JavaScript for visual scripting. The tool is ideal for team collaboration, and the diagram data is stored in a version control-friendly format, making it easy to integrate with your project's repository. The package also includes a demo of a romantic visual novel with nodes for creating a dialog tree.
Key features include:
- Visual diagram editor launched locally in the browser
- Git-friendly data format for teams
- No dependencies (except for TextMeshPro in the demo)
- Not dependent on Render Pipeline (only demo uses URP)
- Generic nodes: point, label, text, image, and clipart with emoji
- Extensible architecture for creating custom plugins in JavaScript
- Example of custom nodes: start dialogue, display dialogue line, end
- OpenSource / MIT License
- Browser compatibility: Chrome, Opera, Edge, Firefox
