Show HN: Davia – Open source visual, editable wiki from your codebase

Hi HN,

We’re Ruben, Afnan, and Theo, and we’re building Davia to solve a common problem: documenting and explaining large codebases is complex. It takes too long to generate even a first draft of a wiki, visuals are essential to understand the structure, internal docs should be editable in the IDE, and most solutions aren’t open.

Davia is an open source tool. You enter the path of your repo, and it generates a visual wiki you can explore and edit. Diagrams are created automatically, and you can update everything either in your IDE or in a Notion-like editor.

The project is still early, and we’d love to hear feedback, ideas, or experiences from anyone interested in documenting and sharing code internally.

Looks interesting and would love to try it out on my side project, but it'd be great if you could add your own package (https://github.com/davialabs/davia/tree/main/packages/agent) as a showcase.

This looks like it could be a sensible way to use LLMs in programming, although I'm not convinced AI-generated documentation can give meaningful explanations rather than paraphrase. However, since the generated wiki is editable, it seems it can be used to give a kick start to internal documentation and let the actual devs step in when it's required. I'm skittish about genAI in the workplace (or anywhere really) but this could be valuable.

However, and this might have been naïve of me, but I expected some sort of local model. And I see that you have to bring in your own vendor API keys, which implies that you let AI companies mine your codebase. Isn't that a no-go for most companies? So far I've only worked in places that banned ChatGPT over IP concerns like these. Is it already common for businesses to feed their codebases to third party LLMs?

Thanks! We’ve actually added our own package as a showcase: https://davia.ai/share/d9c79723-11a6-4a5b-a14b-04ddaa9f123f/....

Exactly. The wiki is editable so AI gives a first draft, and developers refine it. Some companies are fine with vendor APIs, but we’ll add local model support for full privacy.

It's just one short page? Or am I missing something?

Looks interesting but it needs some demos using real world complex projects.

Point it at famous open source projects like React, or three.js, and use those as examples on the homepage.

There are actually 5 sub-pages. Also, the link I sent is a ‘share’ version, so it’s not editable once published.

Thanks! On our homepage (https://davia.ai/showcase) we already showcase examples like AI SDK, E2B, GPT OSS, and Transformers. We’ll also add more examples directly on our GitHub soon.
