Zeta: An Open-Source Local-First Agent OS Defined by Markdown
remilouf · x · 2026-07-30
Developer Rémi Louf open-sourced Zeta, a local-first operating system for durable agents.
The project's core feature is that each agent is entirely defined by a single Markdown file, containing the events it accepts, the tools it can use, and its prompts. The system logs all events, model prompts, and tool calls into a project-local SQLite database, allowing developers to precisely replay the agent's execution path to easily debug unexpected behaviors.
