Your GitHub history, written in stars

Every commit
deserves a sky.

Codex Stellarum transforms your contribution history into a personalised vintage star atlas — rendered in the style of 18th-century celestial cartography. Each commit is a star. Your work, visible at last.

The process

Three steps from commit to cosmos

I

Connect your GitHub

Authorise read-only access to your public or private contribution history. We read commits — nothing else.

II

We chart your sky

Every commit becomes a star. Repositories form constellations. Active periods glow as nebulae. The rendering engine applies 18th-century cartographic styling.

III

Receive your atlas

Share the watermarked web render for free, or unlock a print-ready file. We ship physical posters worldwide via premium print-on-demand.
