Mason is a development agent I work with through chat. I give it product direction, and it turns that direction into working software: exploring an idea, building and testing features, working across repositories, and getting finished apps running.
Mason works in the homelab development environment on a dedicated Proxmox VPS. It builds in the local development workspace, keeps multiple apps running independently, and can take a project from prototype through deployment. With access to coding agents including Codex and Claude Code, it handles both direct implementation and larger, multi-agent development work.
