👋 Hey Product Hunt community! I'm Liam, co-founder of CodeViz along with Will. We're thrilled to officially launch our VS Code extension that transforms how developers understand and navigate code. CodeViz turns source code into interactive visual maps, from high-level architecture down to function calls. We built this tool because, like many developers, we were frustrated spending 70% of our time just reading and understanding existing code instead of building software. Our core belief is that code should be as easy to understand visually - as it is during whiteboard sessions. That's why we've created an extension that generates real-time, navigable diagrams right in your IDE. Who's CodeViz for? - Engineers navigating complex, unfamiliar codebases - Teams onboarding new developers - Open-source contributors trying to understand project structure - Anyone who's ever been lost in a sea of spaghetti code! Here's what you can do with CodeViz: 🔍 Interactive Call Graphs: Click on any function to see a chain of upstream and downstream references. Navigate your codebase using the call stack and see, in one view, everywhere your functions are called. 🏗️ AI-Powered Architecture Diagrams: Get an instant C4 diagram of your system architecture. We detect important files and use LLMs to build nested diagrams at the container and component level. 🔄 On-Demand Diagrams: Want to understand how a specific file works, how data flows through the stack, or something else? Just ask our System Flow Visualizer. We're already seeing adoption from engineers at companies like Amazon, Roblox, and Microsoft. Whether you're a part-time hacker or part of a Fortune 500 dev team, CodeViz scales to any project size. CodeViz is available now in the VS Code Marketplace. We offer basic features for free, with a paid tier for more resource-intensive tools like detailed architecture diagrams. We'd love for you to try CodeViz and let us know what you think! We're eager to hear your feedback and suggestions to make CodeViz even better. Thanks for your support, and happy coding!

Fascinating Liam! And big congrats on reaching this milestone with the launch! Do you see visual codebase maps replacing API documentation?

@gdbroman that's a really good question. I believe internal documentation will certainly be replaced, but external API docs will still remain in some form - with LLMs interfacing with them directly. CodeViz will ultimately make it easy to 'plug in' external APIs into your codebase

This is brilliant, I can't imagine the number of times I had to walk through the entire codebase to get a developer to understand how they can contribute, and the number of times I spent hours trying to understand a codebase to start working on it. I haven't had the chance to actually play with it but do you happen to have free trials for new starters ?

@daniel_xpo Yes! There's a 3 day free trial for the pro plan. Most of the functionality that's in our images & videos are free - including top level architecture diagram, function call graph, and a few generations of chat-triggered visualizations

Congratulations on the launch of CodeViz! The visual mapping of codebases is a revolutionary approach to enhancing developer productivity and understanding. How do you envision expanding CodeViz to support more programming languages and integrate with other IDEs, possibly adding collaborative features for team environments?

Had a friend as principal engineer and saw first hand he's spending hours to understand the codes from others and even from himself, I'll tell him to check this out. Congrats on the launch @liam_prevelige 🤠

@ali_eskandari thanks Ali! Reading and understanding code is a big problem even for experienced engineers

Looks interesting, a close friend of mine runs a web-development agency based out in India. Shared with him

@pradhumn_vijayvargiya Can't wait to hear what he thinks! Thanks for passing CodeViz along!

This looks super useful for diving into new codebases! I'd love to see support for more IDEs beyond just VS Code though. Also, it'd be awesome if there was a way to share these visualizations with team members who might not have the extension installed. Still, definitely gonna give this a try on my next project!

@andyroamer Thanks for the feedback! CodeViz currently supports sharing diagrams with teammates! The feature is great for readme's and shareable directly through a mermaid renderer https://mermaid.live/
