Two ways to take part

Track A · Zero setup · Recommended

Civic Spark, in your browser

The recommended quickstart sandbox. Starter projects preloaded, nothing to install, no GitHub account needed: download your project as a zip and attach it to your entry.

Track B · Your own tools

Your laptop, your workflow

Claude Code in your terminal or editor, Python or Jupyter, or plain Git. Your team shares one GitHub repository and links it from your entry.

No AI required. A spreadsheet chart, a deterministic script, a plain web page, or a cleaned dataset is fully welcome and judged on the same terms.

Enter your project

Every team enters here, once. No code required — a dataset, a map, or a well-documented question is a real submission.
