Read the full description
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.
