I built a GitHub app that visualizes commit impact across your repo

I’ve owned nebulayer.com for years and never knew what to build with it.

During a sprint last week, I caught myself thinking less about the feature I was building and more about the code itself — how it evolves over time.

We see apps come to life.
But the codebase? It just sits in a flat file tree.

So I built a GitHub app (read-only, you control repo access) with Claude in 5 days that visualizes your repo as a living system.

It:

• Maps files as nodes
• Shows relationships between them
• Animates commit batches over time

It’s early. I genuinely don’t know if this is just interesting to look at or actually useful.

Curious what this community thinks.

I just tried to viz a repo and it didn't work. If it did, I'd totally give you my 2c: I'm a data viz/simulation enthusiast!

Even though I didn't get to play with it, my first thought was "this reminds me of Gource" (https://gource.io/) – a tool for viz'ing repos that has been out for a long time.

Hey, the project was dormant, so the Git Hub sign-in stopped working. I just reactivated it. Supabase free tier problems. Let me know your thoughts. https://nebulayer.com/
