Open source Claude Code web/Codex Cloud/Devin alternative
Join the Discord to talk more about Manaflow!
Manaflow lets you spawn Claude Code, Codex CLI, Cursor CLI, Gemini CLI, Amp, Opencode, and other coding agent CLIs in parallel across multiple tasks.
Every run spins up an isolated VS Code workspace either in the cloud or in a local Docker container with the git diff view, terminal, and dev server preview ready so parallel agent work stays verifiable, fast, and ready to ship.
|
Spawn Claude Code, Codex CLI, Gemini CLI, and other agents simultaneously. Select your model, write your prompt, and let multiple agents work on your codebase in parallel. |
|
|
Each agent runs in its own sandboxed environment with full VS Code, source control, and terminal access. Watch the AI think and code in real-time. |
|
Preview your app directly in the workspace while agents make changes. Embedded browser shows your dev server output alongside the code. |
|
|
Review diffs, squash and merge, or open pull requests directly from the workspace. View GitHub Action results and CI status without leaving Manaflow. |
|
See your agent's entire workspace at a glance—VS Code editor, Claude Code TUI, and VNC browser preview all in one view. Monitor exactly what your agent sees and does. |
|
|
Automatically highlight risky code changes with color-coded annotations. Focus your review on the lines that matter most. |
Manaflow supports macOS. Linux in beta. Windows coming soon.
