I want to start with something honest.

GitHub profiles are boring. A grid of green squares, a list of repos, a follower count. None of it tells you who that developer actually is. None of it shows the story behind the code, which projects they care about, which ones they abandoned, whether they have been consistently shipping or quietly going quiet.

So I built Stack Universe as a side project. A crazy idea I couldn't get out of my head.

What It Is:

Stack Universe takes any GitHub username and generates a unique 3D solar system from their public data.

Your repos become planets. Size = star count. Orbit speed = days since last push. Color = primary language. Your commit messages float across the system as shooting stars, real ones, pulled from your actual GitHub events. Your forks drift as asteroids in the belt. Your central star scales from a tiny dwarf to a pulsing hypergiant based on your total repos and stars.

Every developer gets a permanent URL, their coordinate in the multiverse.

How It Grew:

I shipped it in phases over about a month, each one adding a meaningful layer.

Phase 1 was the core visualization. Phase 2 added real repo health scores that drive planet appearance, unhealthy repos get stormy red atmospheres, healthy ones glow clean. Phase 3 made it live, GitHub Actions runs become space weather. Failing builds crack your planets. Deploy streaks build golden auras. Phase 4 added GitHub OAuth so developers can claim their universe permanently and embed it in their README. Phase 5 added a full AI layer powered by Groq, a universe narrator that generates a dramatic monologue about your career, a roast mode that reads your actual repos and destroys you, a weekly horoscope, and a developer identity panel that assigns you a personality type based on your real data.

My own roast said I had "main character energy in an empty room." It was accurate. I shipped it anyway.

What I Learned:

I am still learning and improving with every phase I ship. This project taught me React Three Fiber, procedural 3D generation, GitHub API design, Groq prompt engineering, and about a hundred smaller things I didn't know I didn't know.

The most valuable thing wasn't technical though. It was a comment from a user that stopped me mid-build:

"Same data, but way more engaging when it talks back."

That one sentence became the product philosophy. GitHub has always had the data. Stack Universe just gives it a voice.

Where It Is Now

Five phases shipped. Real users exploring real universes. Beautiful enough to share, intelligent enough to be useful, personal enough to feel like yours.

Phase 6 is next = an explorable multiverse where you fly a spaceship between real developers' universes. Phase 7 brings a full analytics dashboard with graphs and charts for the professional use case. The roadmap is long and I am building it one phase at a time.

If you want to see yours = Stack Universe

Honest feedback always welcome. I read every comment and every piece of feedback has directly shaped what gets built next.
