Caldera turns your Obsidian vault into a public, self-updating profile page and a digital garden of notes you grow in public. Notes are marked as seedling, budding, or evergreen with a license you choose, and backlinks appear across friends' gardens when you link to their notes. Private by default, with contact details stripped, Caldera is free, open source, and self-hostable.
