Product Positioning & Context
Caldera turns your Obsidian vault into a public page that updates itself, and a digital garden of notes you grow in public. Plant a note and it becomes a page marked seedling, budding or evergreen, with a license you choose. Link to a note in a friend's garden and the backlink appears on theirs. Private by default: nothing leaves your vault unless you choose it, and contact details are stripped. Free, open source and self-hostable.

Community Voice & Feedback
Congrats Mike on launching Caldera. Hashing every garden note into a signed manifest is a thoughtful touch, since it gives a public note a verifiable author and date without needing an account. On your question about links between gardens: when I link to [[@handle/Their note]] and they later rewrite it, does my link follow the latest version or point to the hash I saw? I would want the option to pin it, the way a citation does.
mostly it's knowing nobody's gonna judge the half finished ones, i've got way more unfinished notes than polished ones
Cool that Caldera turns my Obsidian vault into a living profile with linked notes, so years of thinking actually become something shareable.
I'd want to try this without rearranging my whole vault. Does it work with an existing Obsidian setup, including custom folders and plugins?
The seedling and evergreen labels hit home. My vault is full of notes I keep meaning to revisit but never quite finish.
This is the kind of thing I'd use instead of spending a weekend trying to build my own notes site.
If I unpublish a note, what happens to copies already shared elsewhere?
Hi Product Hunt! I'm Mike. I keep almost everything in Obsidian, about 4,000 notes, and two things bugged me. My notes never turned into anything other people could see. And the public "digital gardens" people do build are islands: you can't link from your garden into a friend's.
Caldera fixes both. It reads your vault on your device and publishes a living profile (daily journal, activity, timeline, projects) that refreshes itself every few hours. With 0.5 you can plant notes in a Garden folder and each one becomes a page, and [[@handle/Note]] links connect gardens with backlinks on both sides. Every note is hashed into a signed manifest, so authorship travels with it.
It's free and open source (MIT plugin, AGPL hub), and setup is one prompt you paste into Claude Code, Codex or Cursor.
I'd love feedback on two things: what would make you plant notes in public, and what you'd want a link between two gardens to do.
