Codex Stellarum

Your code disappears into production. We put it on the wall. GitHub contributions rendered as 17th-century star atlas prints.

We looked for something beautiful to frame a developer's work.

We found screenshots of green grids.

So we built this instead.

@DanielSmidstrup Atlas.

@PeterOmogo2 That means a lot, Peter. The three years are yours. We only drew the map.

@gabe__nunez @vercel Three years at Vercel, and the same three years of your GitHub turned into a sky. A gift from us to mark the occasion, Gabe.

[Codex Stellarum @codex_stellarum]

@github In the sky.

Not all great work happens at a desk, and not all @github histories should stay trapped in a grid.

We turn them into celestial atlases.

[Codex Stellarum @codex_stellarum]

It is a crime, agreed @hungv47 .
Though it just crossed 400, sitting at 414 now, so the tide is turning. Either way it deserved a proper sky, so here is agent-skills charted as a star atlas, every GitHub star a star, climbing and accelerating. The kind of repo whose sky is about to get a lot brighter.

[Codex Stellarum @codex_stellarum]

@pvncher @RepoPrompt @github Charted repoprompt-ce as a rising sky, every GitHub star a star, launch to 68 in three weeks. You can watch it go from empty to bright. Lovely repo, and the context-engineering angle is a smart place to plant a flag.

[Codex Stellarum @codex_stellarum]

Raimon's whole thing is encouraging people to chase the work with courage. He asked what people had built this year, so we turned his answer into a sky. This is the reaction we build for. Good luck out there.

[Raimon @raimonvibe]

@codex_stellarum Thank you for the lovely preview, I really appreciate the creativity behind Codex Stellarum. Beautiful work!

⭐️⭐️⭐️⭐️⭐️⭐️⭐️

[Codex Stellarum @codex_stellarum]

@raimonvibe Thank you, Raimon. Your number deserved more than a green grid. Glad the sky did it justice.

@sophie_launch Hi Sophie, founder in London here. I
build Codex Stellarum, which renders GitHub contribution histories as star atlases rather than the usual green grid. Made in London, always happy to meet other UK and EU builders.

[Codex Stellarum @codex_stellarum]

Contributing to Supabase at this level is no small thing, and the atlas catches all of it, not just that. Charted your whole GitHub, five years and 3,553 contributions from 2022 to now. The Postgres platform work is in there alongside everything else. A good sky to have built this early.

[Codex Stellarum @codex_stellarum]

@ShaanVP I own dumdummies dot ai. If you know, you know.

[Codex Stellarum @codex_stellarum]

@sama The early web felt handmade. Every page was someone's personal sky, slightly broken, clearly built by a human. Most of what replaced it is optimised and identical. The handmade feeling is the thing worth rebuilding.

[Codex Stellarum @codex_stellarum]

@CraigMerry @tensor_rotator Since the thread is about charting contributions, here is the other way to do it. Your last three years as a star atlas rather than a bar chart. 11,892 stars, with the recent ring blazing exactly where your quarterly chart spikes. Same story, told as a sky.

[Codex Stellarum @codex_stellarum]

@hck_lab Ratio activitatis is a good one. Felt right to give commits per day the same Latin formality the old star catalogues used. Glad it landed.

[Codex Stellarum @codex_stellarum]

We turned Marcin's contribution history into a star atlas. The catalogue descriptions are in Latin, the way the 17th-century atlases were. His reaction below is the version of a review we care about.

[Marcin HCK Firmuga @hck_lab]

@codex_stellarum @github Wow, @codex_stellarum what a great detaled art! It looks so cool, and here is great descriptions.
Keep your work doing, its good and great motivating ;)

[Codex Stellarum @codex_stellarum]

@ArtemR Ah, noted, and apologies for the dated bio. A reader from the era you were running it, then. Either way, sixteen years of contributions made a good sky.

[Codex Stellarum @codex_stellarum]

@sidahuj Charted blender-mcp as a rising sky, 22,327 stars from launch to now. The chart fills up as the stars arrive, sparse in early 2025, dense by today. A fitting way to mark the milestone.
