What is CodeViz?
CodeViz is a Visual Studio Code extension that generates interactive diagrams of your codebase, making it easier to understand how different parts of your code connect and interact. Instead of reading through files individually, you get visual maps that show the structure and relationships within your code. It works particularly well when you're navigating unfamiliar codebases, onboarding new team members, or managing large projects where the overall architecture isn't immediately obvious. The tool uses AI to help you search and explore your code using natural language, and it processes data locally to keep your code private.
Key Features
Interactive code diagrams
visual representations of your codebase structure and dependencies
Click-to-code navigation
jump directly from diagrams to the relevant source files
Natural language search
find code using everyday language rather than syntax
AI query recommendations
the tool suggests relevant queries based on what you're looking at
Multi-language support
handles various programming languages through LLM integration
Local processing option
analyse your code without sending it to external servers
Pros & Cons
Advantages
- Reduces time spent understanding unfamiliar code by providing visual context
- Improves onboarding for new developers joining a project or team
- Works directly in VS Code, so you don't need separate tools or browser tabs
- Privacy-friendly option to process code locally rather than on cloud servers
Limitations
- Relies on VS Code as your editor; not available for other development environments
- Quality of diagrams and AI suggestions may vary depending on code complexity and language
Use Cases
Onboarding new team members by visualising project structure and dependencies
Navigating legacy codebases to understand how different modules interact
Code reviews where visual representation helps explain architectural decisions
Planning refactoring work by seeing the current code organisation clearly
Knowledge transfer when developers leave a project or team
