The software underneath.
Orbino is built with Ruby, Ruby on Rails, PostgreSQL, and Hotwire's Turbo and Stimulus. Propshaft, importmap, Puma, and the wider open-source community make a small, responsive application possible.
Kamal supports deployment, and GlitchTip supports error monitoring. Thanks to everyone who maintains these tools.
A human project with AI assistance.
AI tools assisted with development and data review. The choices and limitations are documented in the atlas. Gameplay uses fixed rules and a frozen dataset; no AI judges your moves.
