Work with code visually.
Don't get lost in text.
AI helps you write code faster. VizDev helps you understand it by building a living knowledge graph of your codebase and turning it into an interactive, explorable map that stays connected to the source.
Blazing fast analysis.
Runs on your machine.
No cloud, tokens optional.
AI wrote it. You still own it.
Review what an agent changed without surrendering your judgment to opaque AI reasoning.
A shared view for complex work.
Make refactors, reviews and security investigations easier to follow, document and explain.
Code shouldn’t feel like a maze.
Navigate purpose-built visuals shaped by code experts to make relationships easier to understand.
A living graph of your code
Most tools treat code as flat text, where the connections are invisible. VizDev builds a source-grounded knowledge graph of your codebase, then turns it into interactive views designed to help you investigate, understand, and act.
Explore, annotate and
share your discoveries
Move freely through your codebase, uncover the relationships that matter and capture what you learn.
Source-to-sink paths
Reveal every discovered call path between two functions and move directly to the relevant code.
Interactive visual code diffs
Turn code changes into an explorable view, so you can see what changed and investigate the impact with context.
VizDev builds its model directly from the code and keeps every visual connected to the source. Click through to see where a function is defined or where a call occurs.
Verify every insight
against the source
File maps
Understand how files connect across part, or all, of a project.
Control-flow graphs
Follow branches, loops, exits and exception paths through a function.
Coverage and metadata overlays
Add test coverage, performance and dynamic-analysis context to the map.
Understand the radius of changes before you ship. Move between levels to investigate and solve problems in context.
Solve problems at
every
level of code
Keep agent work grounded
Agent-produced views stay connected to the source. Trace the reasoning and verify the result.
Collaborate with agents in real time
Exchange context, review AI output and refine the live map alongside your code.
Works with your coding agents
Integrates with Claude Code, Cursor, OpenAI Codex, OpenCode and Gemini CLI.
VizDev gives you and your coding agents access to the same source-grounded knowledge graph, so understanding can be built and shared both ways.

Built around the
way developers work
“VizDev improves my workflow without getting in the way of it, which I feel like is the downfall of a lot of tools.”
Anna
Security Researcher
“VizDev really helped me evaluate risk in new code quickly. It was easy to map out how the code I cared about was connected, and I could show that picture to co-workers so they could see for themselves.”
Martin
Aerospace
"VizDev allows me to work with large codebases in an intuitive and relational way. I really enjoy how easy it is to see how code is structured."

Open your project
Install VizDev in your IDE and open a repository. VizDev indexes the workspace locally when you create your first graph.
Map what matters
See which languages shape the project, explore how files connect, or zoom into a function to follow its control flow.
Orient and act
Navigate to source, focus the view, add annotations, save your progress and share what you have learned.
Works out of the box.

Frequently
asked questions
VizDev is a code analysis and visualization framework that creates an interactive, source-linked visual model of your codebase that you can interact with via an IDE, the command-line, or a coding agent. It helps you explore relationships, trace paths, navigate to source and document what you learn.
VizDev is built for developers, engineering teams, AppSec professionals and vibe coders who want to understand and interact with unfamiliar, fast-changing or AI-generated code more quickly.
No. VizDev generates its maps directly from the code using a local analysis engine written in Rust. AI integrations are optional and let you exchange context and annotations with supported coding agents.
No. VizDev’s analysis runs locally, and your code stays on your machine.
VizDev’s builtin analysis tooling supports C, C#, C++, Go, Java, JavaScript, Python, Rust and TypeScript. Third-party analysis tools can extend VizDev to any language with appropriate analysis support.
Yes. VizDev provides integration for Claude Code, Cursor, OpenAI Codex, OpenCode and Gemini CLI, allowing agents to explore through VizDev and exchange annotations and saved views with you.
VizDev runs locally and can be used through supported editor integrations or from the command line, where developers and agents can access the same code analysis.
Join the closed beta. VizDev is onboarding a limited number of participants who can share feedback and real development use cases.
