A LinkedIn for developers
LinkedIn is built around job titles and posts. Caldera is a professional profile for developers built from the work itself: sign up with GitHub and your repos become a living city, your page shows commits, languages and AI usage, and people find and follow you by what you build.

How it differs
| Typical professional network | Caldera | |
|---|---|---|
| Profile source | What you type | Your GitHub (and optionally your Obsidian vault), updated automatically |
| Proof of work | Endorsements and posts | Repos, commits, AI coding activity |
| Connections | Requests | Follow; follow each other and you are friends |
| Finding people | Search by title | Search by what people build; Feed posts matched to people |
What you get

- Feed posts: "I need..." and "I recommend..." go to the people who match.
- Direct messages, with a request first for people who aren't friends yet.
- A listing in People, searchable by what you build.

Questions
Is Caldera a replacement for LinkedIn?
It is a complement focused on builders: it shows the work behind the title.
Do I need Obsidian?
No. GitHub alone gives you a page and a city. Obsidian adds a journal, AI usage and encrypted note sharing.
Can recruiters message me?
Members can send you one message request; you accept, ignore or block it.
Is it free?
Yes.
