Duet vs Conductor

Conductor (by Melty Labs) is a macOS app that lets you run multiple Claude Code or Codex agents in parallel on your local machine. Duet is a managed cloud platform where AI agents run 24/7 with team context. Both aim to make AI agents more useful for real work — but they take very different approaches.

What is Conductor?

Conductor is a macOS desktop application that runs multiple AI coding agents simultaneously on your Mac. Built by a YC-backed 4-person team, it treats Claude Code and Codex instances like a team of junior engineers — dispatch them in parallel, review diffs, merge the best results.

Key characteristics:

• Parallel execution of Claude Code and Codex agents
• Automated git worktree management per agent
• Visual dashboard for monitoring agent progress
• Diff-first code review workflow
• Free software — you pay only for your existing AI subscriptions (Claude API, Claude Max, etc.)
• macOS only (Apple Silicon required)

What is Duet?

Duet is a cloud dev environment that gives every user and team a private cloud server with a persistent, always-on AI agent. Your agent has its own server with persistent memory, 500+ integrations out of the box, built-in app hosting, and scheduling — with a team interface where humans and the agent collaborate through channels and threads.

Head-to-Head Comparison

Where Conductor Excels

Parallel coding speed. Conductor's core feature — running 3-5+ Claude Code agents on separate tasks simultaneously — is excellent for developers who want to parallelize coding work. Dispatch multiple features, review diffs, merge winners.

Zero additional cost. Conductor itself is free. You use your existing Claude or OpenAI credentials. No new subscription needed.

Local execution. Everything runs on your machine. If you're concerned about sending data to a cloud platform, Conductor keeps it local.

Beautiful UI. For an early-stage product, Conductor has a polished visual dashboard for monitoring multiple agents. The diff-first review workflow is well-designed.

Where Duet Excels

Always-on cloud agent. Conductor stops when your Mac sleeps. Duet runs 24/7 on a cloud server — no laptop required. Your agent monitors channels, runs scheduled tasks, and responds to events around the clock.

500+ integrations out of the box. Conductor has zero integrations — it's a local agent runner with no connection to external services. Duet ships with 500+ managed integrations via Composio and MCP, so your agent can work with Linear, Slack, Gmail, Google Calendar, and hundreds more without any setup.

Beyond code. Conductor only dispatches coding agents. Duet's agent handles email, research, operations, GTM, scheduling, content creation — the full operational stack.

Team collaboration. Conductor is a single-user tool with zero collaboration features. Duet is built for teams — shared channels, threads, organizational context, and multiple team members interacting with the same agent.

Persistent memory. Conductor has no concept of memory beyond git commits. Duet's agent accumulates organizational knowledge over time — decisions, preferences, context, relationships — and gets better the longer you use it.

True orchestration. Conductor does parallel execution, not orchestration. It can't chain agent outputs, define task dependencies, or create multi-step workflows. Duet supports workflow orchestration with scheduling, event triggers, and agent skills that compose together.

Cross-platform. Conductor requires a Mac with Apple Silicon. Duet works on any device with a browser — desktop, mobile, any OS.

Production stability. Conductor is at v0.36 with a 4-person team and $500K in funding. Early-stage software with expected rough edges. Duet is a production platform.

They Could Be Complementary

These tools aren't necessarily competitors. A developer on a team using Duet could also use Conductor locally to speed up their individual coding sessions. Conductor parallelizes coding tasks on your machine; Duet orchestrates AI agents across your team in the cloud.

The question is whether you need a local coding parallelizer or a team agent platform. Most teams need the latter.

Who Should Use What?

Choose Conductor if:

• You're a solo developer on a Mac who wants to parallelize Claude Code sessions
• Your work is 100% coding and you just want to go faster
• You don't need team collaboration, scheduling, or non-code capabilities
• You want zero additional cost (free tool, use existing API keys)

Choose Duet if:

• You're a team that needs shared AI context and collaborative workflows
• You want an always-on agent that works when your laptop is closed
• You need AI for more than coding — email, research, ops, GTM, integrations
• You want a production-grade platform, not an early-stage desktop app
• You need cross-platform access from any device

The Bottom Line

Conductor is a clever local tool for parallelizing coding agents. It does one thing well — run multiple Claude Code sessions side by side. But it's a single-user, macOS-only, code-only, early-stage product with no persistence, no team features, and no orchestration beyond "run things in parallel."

Duet is a full team agent platform. If you need more than parallel coding sessions — and most teams do — Duet is where you should start.
