Caldera

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.

Caldera offers startups and independent builders a free, open source way to build a public presence from the notes and repositories they already maintain, without adding a separate publishing workflow. Its privacy-first defaults and self-hosting option give teams full control over what they share, while cross-garden backlinks create organic discovery among technical peers.
