69. Moonphase

Astronomy events calendar

by Zoe Castellanos

Preview of Moonphase, a calendar app

Description

The brief was an astronomy events calendar — nothing more. Moonphase is what came out: a dark & moody dashboard that gets out of the way once you have what you came for.

  • Loads in under a second on a cold cache
  • Dark and light, following the system
  • No accounts, no cookies, nothing stored server-side

Made with Claude Code and Mapbox. Roughly 80% of the first draft survived to production, which is not something I could have said about any project before this one.

Open to feedback, especially on the parts I have stopped being able to see.

Workflow

  1. Generated the first pass in Claude Code

    Kept the prompts in the repo next to what they produced, so a regeneration six months later starts from the same place.
