Visor is a powerful VS Code extension that generates real-time, interactive flowcharts for your code. It helps you understand, debug, and document complex logic by transforming it into a clear visual representation.
- Real-Time Flowchart Generation: Flowcharts automatically update as you navigate or edit your code. Place your cursor inside a function, and Visor instantly visualizes its logic.
- Bidirectional Navigation: Click on a node in the flowchart to jump to the corresponding code, and watch the flowchart highlight as you move your cursor through the code.
- Multi-Language Support: Works out of the box with Python, TypeScript/JavaScript, Java, C++, C, and Rust. It supports a wide range of code constructs including functions, classes, loops, conditionals, and exceptions.
- Cyclomatic Complexity Analysis: Get instant feedback on your code's complexity with real-time metrics and visual indicators (
⚠️ , 🔴, 🚨) on complex nodes. - Enhanced Readability: Flowcharts use semantic nodes to visually distinguish between different code elements—like decisions (diamond shape), loops (stadium shape), and processes (rectangle). The design is theme-aware and professionally styled.
- Flexible Viewing: View flowcharts in the VS Code sidebar or in a dedicated external window, perfect for multi-monitor setups.
- Export Capabilities: Easily export your flowcharts as high-quality SVG (vector) or PNG (raster) images for documentation.
- Install the Visor extension from the VS Code Marketplace.
- Open a supported code file (Python, C++, etc.).
- Click the Visor icon in the Activity Bar to open the panel.
- Place your cursor inside a function to see the flowchart instantly appear.
You can customize Visor's behavior through the VS Code settings (Cmd/Ctrl + ,). Search for "Visor" to adjust settings for:
- Complexity Thresholds: Set your own ratings for low, medium, and high complexity.
- Visuals: Customize how complexity indicators are displayed.
{
"visor.complexity.enabled": true,
"visor.complexity.thresholds.low": 5,
"visor.complexity.thresholds.medium": 10,
"visor.complexity.thresholds.high": 20
}Visor is built on Tree-sitter for robust code parsing and Mermaid.js for high-quality diagram rendering. All code analysis and flowchart generation are performed locally on your machine, ensuring your code remains completely private and secure.
For details on the optional LLM-based label conversion (providers, caching, privacy, configuration), see the doc: LLM Label Conversion. Editor Compatibility: Visor works seamlessly with VS Code, Cursor, and Windsurf editors. The extension automatically detects your environment and applies compatibility optimizations when needed.
