Cydonia is an open-source desktop workspace designed for developers to manage coding agents and their output as durable files on disk.
It serves as a project-oriented environment where agents that support the Agent Communication Protocol (ACP) can operate, replacing traditional chat-log interfaces with persistent artifacts like articles, boards, and tables.
