Manaflow

What is Manaflow?

Manaflow is an open source applied AI lab focused on the developer experience of working with AI coding agents. Its core product, cmux, is a native macOS terminal that lets engineers run and manage multiple coding agents — such as Claude Code, Codex, Gemini CLI, Amp, and Opencode — simultaneously within isolated workspaces. Beyond terminal management, Manaflow ships complementary tools including a heatmap diff viewer for code reviews, a UI-aware code review agent, and a curated algorithmic feed that lets coding agents escalate urgent tasks for human review.

Key Features

• Universal Coding Agent Manager

  cmux supports Claude Code, Codex, Gemini CLI, Amp, Opencode, and other coding CLIs from a single native macOS terminal, eliminating the need to juggle separate tools for each agent.

• Parallel Agent Orchestration

  Run multiple coding agents concurrently in isolated VS Code workspaces with vertical tabs, enabling simultaneous build and planning cycles without context-switching overhead.

• Heatmap Diff Viewer

  Visual code review tool that renders diffs as heatmaps, making it faster to spot high-change areas and prioritize review effort across large pull requests.

• UI-Aware Code Review Agent

  Automated agent that takes screenshots of code diffs involving UI changes, giving reviewers visual context alongside the raw code diff.

• Agent Escalation Feed

  Curated algorithmic feed (powered by X/Twitter) that surfaces the most urgent tasks flagged by coding agents, keeping humans in the loop without manual monitoring.

• One-Click PR Creation & Workspace Monitoring

  Integrated workflow for creating pull requests and monitoring full workspace activity directly from the terminal, with live web preview support built in.

Use Cases

• Multi-Agent Development : Engineers running several AI coding agents in parallel can manage all sessions from a single cmux window, with isolated workspaces preventing agent interference.
• AI-Assisted Code Review : Teams can use the heatmap diff viewer and UI screenshot agent to conduct faster, more context-rich code reviews on complex or visually intensive pull requests.
• Human-in-the-Loop Oversight : Tech leads can rely on the escalation feed to surface only the most critical agent decisions that require human judgment, reducing noise from routine agent activity.
• Rapid Feature Shipping : Solo developers and small teams can leverage parallel agent orchestration and one-click PR creation to compress build cycles and ship features faster.
