Parallel Code

Parallel Code, developed by Johannes Millan as open-source software, is a desktop application that dispatches multiple AI coding agents simultaneously, each working in isolated git branches and worktrees, letting users review diffs and merge successful changes back to the main codebase. Parallel agent execution dispatches AI coding agents in parallel, each in its own worktree, without shared working-copy collisions, and multi-agent support is compatible with Claude Code, Codex CLI, Gemini CLI, Copilot CLI, and Antigravity CLI. The tool is editor-agnostic, working alongside VS Code, Cursor, JetBrains, or Sublime while managing agents, a diff-first review workflow inspects changes individually before integrating, and a keyboard-optimized interface supports remote terminal monitoring via QR code and Wi-Fi. True isolation gives each task its own git branch, preventing overwrites.
