I built 270 AI agents in an Obsidian vault – zero API costs, all open source

A developer built 270 AI agent profiles across 17 divisions using only open-source tools, with zero API costs. The agents are interconnected through an Obsidian vault containing 317 notes and 500+ wikilinks, and the project includes 11 multi-agent playbooks for tasks like launching a SaaS product and security audits. The tech stack includes Ollama, Playwright, Docker, and ChatbotX, and the vault template is available on Gumroad.
