Proliferate: open-source, self-hostable IDE that runs coding agents in parallel

Key points

1. Each task gets its own isolated git worktree with a separate branch, terminal, conversation, and review state, and agents can delegate to child agents within a shared workspace.
2. It supports MCPs, skills, custom tools, and automated workflows for recurring or event-driven runs.
3. The repository shows 266 stars, 54 forks, and 2,904 commits, is AGPL-3.0 licensed, and ships deployment guides for Docker, AWS, GCP, and Azure.
