Codex Stellarum

Most of what we build as developers disappears into production. Tickets close, repositories archive, companies move on. But the rhythm of your work - the late nights before a launch, the quiet weeks between projects, the years of steady effort - that is still there in your contribution history. Every day you contributed becomes a star. Busy days are large and luminous, quiet days are small and faint. Codex Stellarum renders that history not as a grid of coloured squares or a screenshot from a website, but as a star atlas inspired by 17th-century celestial cartography - the kind of object that belongs in a frame next to actual art, not next to the rubber ducks. A non-developer sees it and thinks "that is beautiful." A developer sees it and thinks "wait - those are my contributions." We wrote more about the thinking behind it in our founding essay. in our founding essay at https://codexstellarum.com/blog/why-we-built-codex-stellarum

Your atlas is generated from the contribution data visible on your public GitHub profile. To include private contributions, go to your GitHub profile, click "Contribution settings" next to your contribution graph, and enable "Private contributions". This changes only the count displayed on your profile - your code and repositories remain completely private. You can enable it just long enough for us to fetch your data, then turn it off again.

You can. All you need is their GitHub username. Enter it on the chart page, choose a layout and theme, and place the order. We ship to most countries globally with tracked delivery.

A GitHub profile shows a flat grid of green squares for the past year. We transform your entire contribution history - every year you have been coding - into a star atlas rendered in the visual language of celestial cartography. Three astronomical layouts. Period-appropriate Latin typography. A magnitude legend. Coordinate markings. Each day becomes a star whose size and brightness reflect your activity. The result is printed on museum-quality 200 GSM archival cotton rag paper at 300 DPI using the same giclée process used by galleries. It is designed to look like something from a rare book collection, not from a computer screen.
