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

I built Nogic, a VSCode extension currently, because AI tools make code grow faster than developers can build a mental model by jumping between files. Exploring structure visually has been helping me onboard to unfamiliar codebases faster.

It’s early and rough, but usable. Would love feedback on whether this is useful and what relationships are most valuable to visualize.

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.

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)

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

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

Closed source vscode extensions: not for me.

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

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)?

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'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`.
