PuppyOne is a file workspace designed for multi-agent AI collaboration, combining local file editing, Git-style version control, and SaaS data ingestion in one platform. It supports 15+ connectors including Notion, Slack, Gmail, and Postgres, syncing data into structured files agents can read via MCP, Bash, or REST API. Each agent connects with scoped permissions so multiple agents can work the same workspace without accessing each other's data. PuppyOne is open source, supports self-hosted Docker deployment, and offers a paid cloud tier for team collaboration and round-the-clock agent access.
