Caldera

Your vault becomes a living profile that updates itself, and vaults can befriend each other, share notes as end-to-end encrypted cards, post asks and offers, earn help credits, and give gravity (positive-only kudos).

Private by default. Nothing leaves your vault unless you switch a section on, mark a note caldera: public, or share it with a named friend. Every publish can be previewed first.

What's here

Use it (Obsidian)

Fastest: copy the setup prompt at https://caldera.social/#install into Claude Code, Codex or Cursor. Your AI installs the plugin; restart Obsidian, pick a handle in the Welcome window, and your page opens in the browser.

By hand: download caldera-latest.zip (or the files from the latest GitHub release) into <vault>/.obsidian/plugins/caldera/, restart Obsidian, turn on Caldera.

Beta testers (BRAT): add schoettle-cmd/caldera in the BRAT plugin.

Change your page by editing the note Caldera/profile.md (or ask your AI to); it republishes itself. Guide: https://caldera.social/guide.html

Conventions (all optional): caldera: public on a note lists it publicly; daily notes named YYYY-MM-DD can carry caldera_headline, caldera_focus, caldera_wins, caldera_themes for the daily journal; Caldera/activity.json lets outside tools (calendar, email, git) add daily counts.

Privacy and terms

Hosted service: Privacy Policy and Terms of Service. Delete your hub profile anytime with Caldera: Delete my profile from the hub.

Network use (disclosure)

The plugin contacts only the hub you configure, and only when you publish, sync your inbox, or act (friend, card, ask, offer, gravity). No telemetry, no analytics, no third parties. Your identity keys live in the plugin's data file on your device; export your recovery key from settings.

Run a hub

npm install && npm run build
CALDERA_DATA=./data PORT=8787 node --no-warnings packages/hub/dist/server.js

Develop

npm install
npm run build
npm test          # core (6), hub end-to-end (7), plugin render + publish end-to-end (4)

Principles

Local-first. Keys, not accounts. Everything that matters is signed. Positive-only social signals. Points before money: help credits have no cash value in v0.1.
