Build yourself an AI coworker that actually takes work off your plate

Proliferate opens sources a self-hostable platform for building company-specific background agents that run in isolated sandboxes with access to internal services, triggered by events, and surfaced via live, multiplayer previews for team verification. It targets engineering teams needing end-to-end automated work beyond local agents, with MIT licensing and self-hosting.
