Product Overview
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.
