Every myth here is a measurement. If a rule can't be computed from public git or GitHub data, it doesn't go in.
In 2005 a single commit set off a singularity. It was called git, and everything since has orbited it. In 2008 the universe began to expand: worlds formed around people, cities grew around their ideas, and every time someone left a star, a new light appeared in that world's sky. Most worlds are small and quiet. A few burn so brightly they bend the galaxy around them. New ones are born every second, out at the edge. You are a cartographer of the Commitverse. Your ship, your planet and your map start today.
The Commitverse is a cluster of 14 galaxies around git, the singularity at its centre. Every world (account) belongs to exactly one galaxy. The rules run in this order, so the first one that fits wins (cosmos.js):
| Galaxy | Who lives there | Rule (data) | Look |
|---|---|---|---|
| The Titan Galaxy | The giants of GitHub | 100,000 stars or more | A golden giant elliptical around git |
| The AI Galaxy | Worlds that build AI | AI topics on most of their stars, or one of the AI labs | A violet two-armed spiral |
| The Silent Galaxy | Worlds that went quiet | Archived, or nothing pushed for two years | A dim, distant elliptical: a memorial, not a graveyard |
| The Python, JavaScript, TypeScript, Rust, Go, C & C++, JVM & .NET, Apple & Mobile, Functional and Scripting Galaxies | Everyone else | The family of the world's main language (the Scripting Galaxy takes every language without a galaxy of its own) | Spirals in their languages' colours, one arm per language |
| The Rising Galaxy | Protostars: promising new repos | Created in the last 12 months, among the fastest-climbing | An irregular galaxy of pink star-forming knots; this is where discoveries happen |
Inside a spiral, older worlds sit nearer the core: user IDs are sequential, so a galaxy grew outward the way GitHub did. Inside an elliptical, the brightest worlds sit at the heart.
The universe is reseeded from GitHub every day (universe.yml). Whatever changed becomes history:
- Ignition. When a protostar passes 100,000 ★ it ignites. It leaves the Rising Galaxy, and its world joins the Titans. You see it cross the cluster as a comet.
- Migration. A world whose numbers carry it into another galaxy moves there: it grows into a Titan, falls silent, or turns to AI. The move goes into the migration log and the galactic news.
- Joining. Anyone who stars the project's repository gets a world in the galaxy of their language at the next update.
Before the cluster split up, the Commitverse was drawn as a single galaxy with sectors. That is how it looks in the film, and it is still there at ?galaxy=all. Its sectors were the Ancient Worlds (the oldest accounts) at the core, the Titan Cluster, the AI Nebula, the Language Arms, the Stellar Nursery, the Frontier and the Silent Belt.
A planet (a person) develops with the total stars across its repos. The scale is logarithmic, like a Kardashev scale for open source.
| Level | Stars | The world |
|---|---|---|
| 0 · Dust | 0 | A bare rock, one campfire (the first commit) |
| 1 · Outpost | 1–9 | A few lit huts, dirt tracks |
| 2 · Colony | 10–99 | Towns joined by roads, a first satellite |
| 3 · Civilisation | 100–999 | Night lights visible from orbit, a moon base |
| 4 · Industrial | 1k–9.9k | Megacities, a spaceport launching rockets on every release |
| 5 · Spacefaring | 10k–99k | An orbital ring, a space elevator, fleets of contributor ships |
| 6 · Ecumenopolis | 100k–499k | City lights over the whole night side, ring stations |
| 7 · Galactic | 500k+ | Bends its region: its own halo of light, visible from anywhere |
Each city (repo) has its own tier by its own stars: village, town, city, metropolis. A metropolis gets a landmark tower and its own spaceport.
Two rules keep the world alive:
- Activity keeps the lights on. A planet whose repos go quiet slowly dims: roads crack, greenery takes back the streets. Work brings it back.
- Archived = frozen. Ice spreads over the planet and it drifts into the Silent Galaxy.
Stars measure attention, not quality. The lore says so openly: some of the best code lives on quiet planets, and the guide shows people where.
| Phenomenon | Data | What you see |
|---|---|---|
| Supernova | A repo gains stars explosively (e.g. +5k in a week) | A flash seen across the galaxy, and an entry in the galactic news |
| Comet | A repo that trended hard, then went quiet | Flies across its arm with a fading tail |
| Pulsar | Releases on a steady rhythm | Blinks at its real release cadence |
| Binary stars | Two projects that always change together (co-committed, shared maintainers) | Two worlds orbiting each other |
| Launch | A release tag | A rocket with the version number lifts off the spaceport |
| Impact | A massive refactor or deletion | An asteroid strike: a crater, then regrowth (the demolitions we already show) |
| Gravity | Number of dependents | Heavy libraries bend the space around them; the orbits of dependent worlds lean toward them |
| Storms | Open issues on a district | Weather over that part of a city |
- Claim your planet. Sign in with GitHub, land on your own world, and watch it evolve as you ship.
- Discover. Visit protostars in the Rising Galaxy. If a repo you visited early later reaches 1,000 stars, your flag stays on it as a first discoverer. It's a reason to come back every day, and a real, provable claim ("I found it at 40 stars").
- Travel log. A passport of the worlds you have landed on, stamped with their level when you arrived.
- Expeditions. Guided tours narrated by the AI guide, from verified sources:
- The Great Framework Wars (jQuery → Backbone → Angular → React → Vue → Svelte)
- The Rise of the AI Galaxy
- Ancient Worlds: the code that runs everything
- Galactic news. Supernovae, launches, impacts and new protostars, as a live feed and a daily digest.
True observations from the seeded data. The universe writes its own stories.
- The most influential AI code is tiny. nanoGPT (63k ★) is a city of 24 buildings. micrograd (17k ★) has 10.
- @karpathy's world is 5,659 ★ short of Galactic. Today it is an Ecumenopolis with 494,341 ★.
- @sindresorhus is already Galactic. 1,130 cities, more than a million stars, two orbital rings.
- Some giants live in systems, not on worlds. @dhh's personal world is small (392 ★) because Rails belongs to an organisation's star. The map is honest about where things live.
- Most of a city's past is gone. In Express, two thirds of all lines ever written went into paths that no longer exist.
- The Titan Cluster is heavy. @microsoft alone carries 2.1M ★ across the surveyed repos.
- The name is Commitverse, with Commitropolis as the first city. We don't borrow GitHub's own names (such as "Octoverse").
- Real organisations and people appear as they appear on GitHub (public accounts, public data), with no logos and no invented claims. Framing stays positive or neutral: archived projects go to a memorial belt, and no real project is "swallowed by a black hole".
- The style is awe first and humour second. It should feel like a planetarium show, not a meme.
