Build in public without the busywork
Building in public works best when sharing costs nothing. Caldera turns your GitHub (and optionally your Obsidian notes) into a page that updates itself: a live city of your repos, commits this week, your coding agents at work and a daily journal, plus a Feed to ask for help or recommend tools.

What people can follow
- Your city: repos rising with commits, lit windows for this week, cranes for today.
- Live visitors to your sites parachuting in, if you add the snippet.
- Your coding agents as drones over the repos they are editing.
- A daily journal written from your notes (Obsidian), with only what you approve made public.
Share without extra work
- Follow-ups happen on their own: your page refreshes, and followers see your activity.
- Post milestones or asks on the Feed in one line; share to X, LinkedIn or Bluesky from the post.
- Put the city badge in your README.
Keep private things private
Private repos show without names, or not at all. Journal lines are filtered for private details before publishing. See Show private GitHub activity safely.
