Show HN: Proliferate- open-source, self-hostable Codex for any coding agent

Proliferate is an open-source, self-hostable AI IDE that enables users to run multiple coding agents (Claude Code, Codex, OpenCode, Cursor, Grok, and others) in parallel within a single workspace. Each agent operates in an isolated git worktree with its own branch, terminal, and conversation history, and can delegate work to subagents while sharing integrated tools and workflows. The platform is fully self-hostable with deployment options for Docker, AWS, GCP, Azure, and Kubernetes.
