The GitHub
for game code.
The missing infrastructure for game development — engine-ready assets, forkable indie codebases.
Every game dev
is starting from zero.
If you've ever looked for an open-source game to learn from, or a solid up-to-date template for the genre you're building in, you already know this: the options are ancient, genre-limited, or IP-encumbered. The code that would actually help you is private.
So every developer rebuilds the same systems from scratch — game loops, collision, state machines, entity management. Work that's been done a thousand times, invisible in a thousand private repos.
Months of reinvention before you write a line of original gameplay. The reference code you need exists — it just lives in the private repos of games that shipped and moved on.
Built layer by layer.
To end starting from zero.
Cosmire is being built piece by piece — each layer eliminating another part of the problem. The first two are in development now.
Magnetic Imports
Every asset arrives engine-ready — resource files configured, animations named, spritesheet grids mapped. Built alongside asset creators to eliminate the integration step that wastes everyone's time.
Bedrocks
Release-quality indie codebases — documented, licensed, and forkable. The reference code that should exist but doesn't. Licensed directly from the developers who built it.
More to come
We're building the infrastructure for all game code. What comes after these first two layers is shaped by what developers and creators tell us they still need.
Built by people
who hit the wall.
We didn't read about this problem. We hit it ourselves — building games, studying codebases, and searching for reference code that should have existed and didn't.
Jason has spent years inside the indie game community — playing, building, and studying what makes games worth studying. He knows which codebases are the hidden gems. He hit the same wall this library is built to fix.
Hotaka has worked through the licensing infrastructure that underpins this kind of business from the inside. He also has native Japanese fluency. We have direct access to Japan's prolific indie scene!
Stop rebuilding systems
you've seen a hundred times.
Cosmire gives developers a library of release-quality game code to fork and build from — documented, modular, and ready. Access is coming. Get in early.
