Show HN: Nogic – VS Code extension that visualizes your codebase as a graph

I always liked the idea having relationship based programming (graph programming), but with actual code. Never actually made the effort to make something like that. Pretty neat either way.

All the GitHub links on your extension page are borked (including issues)

From the look of the associated domain it looks like you're going full product, best of luck

I'm a huge proponent of graph & visual analysis of complex systems - would have loved to try this out, but will always skip closed source editor extensions (especially in the age of widespread npm supply chain attacks & vibe coding)

I've tried it, but it's very slow on a not too complex codebase with my M3 Macbook Air.

I'm using another similar one which is buttery smooth, Code Canvas.

I guess it is still useless in Ruby or Ruby on Rails. Standard "find the method declaration" or "used here" do not work in Ruby on Rails. Still, huge companies maintain that Ruby on Rails mess, where you cannot properly investigate, so you just guess and use the search and find option. Those codebases won't be replaced for a while, but good luck working on them. Such a headache!

I used to use Doxygen to create caller and callee graphs to understand code flow. Unfortunately, the tool hasn't really changed in more than a decade.

I've been having great success with LLMs generating Mermaid diagrams and flowcharts from a repo. Claude Code and Cursor both do consistently great jobs. For example: `generate a mermaid swimlanes diagram of the XX logic flow`.

Very cool visualization. However it crashes on a more complex project. I added a folder with 2000+ files(included my assets) and now the visualizer locks up then shows nothing on its tab in VSCode. How do I manually delete old boards so that I can try again with a smaller slice of the code(without assets)?

Nice, I wanted to build something similar for a long time. The coolest thing is to start summarising clusters for very large codebases, which essentially provides an LoD system for the context.

Funny how world is so tiny. I am literally building myself an vscode extension which can abstract an api on top of google colab's vscode extension and I am able to effectively create a sandbox for any python code (I mean to be fair they all still share the same resource but that resource is of google)

I have also hacked together a way for it to create new kernels aka new vm's itself but that becomes really really slow and also I am trying to look at other options to sandbox inside the jupyter notebook itself.

The end result was very messy though so I was literally just currently experimenting with if I could just scrape/automate it from the browser directly.

All in All I must admit that Vscode extensions are/feel very quite competent from what I can gather.

I definitly think more tools like this are needed, but not open sourcing it is a mistake.

You will be quickly replaced by a friendlier competitor.

Closed source vscode extensions: not for me.

Only JS, TypeScript, and Python. You got me all excited for a C visualizer!

Unfortunately the repository links are broken and this is ARR licensed.

From your first page, this looks cool and needed. But as others have posted, I can't get to your github pages.

The illustration gif is way too fast. Hard to understand what is going on. Slow it down 2x or so.
