60/100
A moderate niche opportunity: strong product concept and Obsidian fit, but currently unmonetized with cold-start and single-platform risks.
Founder verdict
MAYBE
Caldera is a well-positioned, privacy-first social layer for Obsidian, but it is unmonetized, early-stage, and faces a cold-start social network and single-platform dependency.
What is Caldera?
Caldera is an early-stage, free and open-source Obsidian plugin that turns a private vault into a public 'living profile' and digital garden, while adding encrypted social features between vaults. It processes notes locally, publishes only selected content, and introduces non-adversarial social mechanics like asks, offers, and gravity. No revenue, pricing, growth, team size, or stage are publicly disclosed; the site positions the product as free and open source.
