Best parallel development AI tools

An open-source desktop application for developers to run and orchestrate multiple coding agents (like Codex, Cursor, Claude Code) in parallel, each within its own isolated Git worktree.

Agor is a next-generation agent orchestration platform for AI coding. It provides a multiplayer, spatial canvas that unifies coding agents like Claude Code, Codex, and Gemini into a single workspace. Teams can visualize, coordinate, and automate complex coding workflows in real-time, using isolated environments to enhance parallel development.
