Superset vs Conductor vs Emdash: Parallel Agent Orchestrators Compared (2026)

Summary

All three tools solve the same problem: running multiple AI coding agents in parallel without merge conflicts. The mechanism is identical across all three. Git worktrees create separate working directories linked to the same repository. Each agent gets its own directory, its own branch, and full filesystem isolation.

The differences are in everything around the worktree: which agents are supported, what platform you can run on, how you review and merge changes, and whether the tool connects to your issue tracker. These differences determine which tool fits your workflow.

Reading the Stats

Superset and Emdash lead on agent flexibility: both work with any CLI agent. Conductor focuses narrower on Claude Code and Codex, trading breadth for a more polished UX. Emdash is the only tool with built-in issue tracker integration. Conductor is the only tool restricted to a single platform. These are architectural decisions, not oversights.

Architecture: How Git Worktrees Enable Parallel Agents

All three tools use the same foundational mechanism. A Git worktree is a separate working directory that shares the same .git directory as your main checkout. Each worktree gets its own branch, its own file state, and its own index. Agents running in separate worktrees cannot overwrite each other's files.

The overhead is minimal. A worktree adds a few kilobytes to your .git directory plus the disk space for tracked files. Compare this to a full clone, which duplicates the entire history. For a 1GB repository, 10 worktrees cost roughly 10GB of disk. 10 clones would cost roughly 10GB plus 10x the Git history.

The Review Bottleneck

Running 10 agents in parallel is easy. Reviewing 10 diffs in parallel is the hard part. Each tool approaches this differently. Superset gives you a syntax-highlighted diff viewer and the option to open any worktree in your preferred editor. Conductor adds automated code review that checks agent output against your project guidelines. Emdash shows CI/CD status alongside diffs so you can see if tests pass before reviewing.

# Without an orchestrator, you manage worktrees manually:
$ git worktree add ../feature-auth -b feature/auth
$ git worktree add ../feature-dashboard -b feature/dashboard
$ git worktree add ../feature-api -b feature/api

# Then start agents in each:
$ cd ../feature-auth && claude "Implement JWT auth"
$ cd ../feature-dashboard && claude "Build admin dashboard"
$ cd ../feature-api && codex "Add REST endpoints"

# Superset, Conductor, and Emdash automate all of this.
# You describe tasks. They create worktrees, start agents,
# and show you the diffs when agents finish.

Agent Support: Which Agents Work With Which Tool

Agent compatibility is the biggest functional differentiator between these three tools. If you only use Claude Code, all three work. If you use multiple agents or want to switch between them, the differences matter.

Superset's approach is the simplest: if an agent has a CLI, it works. No integration required. Emdash takes a similar stance but adds specific configuration for 22+ agents to handle their different output formats. Conductor is the most opinionated, optimizing deeply for Claude Code and Codex at the cost of broader compatibility.

Workflow Integration: Beyond the Terminal

Running agents is step one. The real workflow involves assigning tasks from a backlog, reviewing output, running tests, creating PRs, and merging. This is where the three tools diverge most.

Emdash's issue tracker integration is its clearest differentiator. You pull a Linear ticket, assign it to an agent, the agent works in an isolated worktree, you review the diff, and create a PR, all without leaving the app. Conductor's automated review fills a different gap: it checks whether the agent's output actually follows your project guidelines, catching drift before you spend time reading the diff. Superset stays closer to the terminal, giving you the tools without the workflow opinions.

Platform and Pricing

All three tools are free. None charge for the orchestrator itself. You pay for the underlying AI agent subscriptions (Claude Max, ChatGPT Plus/Pro, etc.).

The platform question is binary for many teams. If anyone on your team uses Linux or Windows, Conductor is off the table. Emdash is the only option with SSH remote support, meaning your agents can run on a beefy dev server while you review from your laptop. Superset currently ships macOS only, but Linux and Windows builds are on the roadmap.

Open Source Considerations

Superset (Apache 2.0) and Emdash (MIT) are both permissively licensed. You can fork, modify, and redistribute. Conductor is proprietary. For teams that require open-source tooling, or want the ability to self-host and modify, this narrows the choice to two.

Where Superset Wins

Superset's 3,200+ stars in 3 days signals strong demand for the "just let me run agents" approach. No opinions about which agent you should use. No workflow integration you have to adopt. A terminal that makes parallel agents easy and gets out of the way.

Where Conductor Wins

Conductor's automated review feature is the most interesting innovation in this category. The review bottleneck is real: 10 agents generating diffs is only useful if you can review 10 diffs efficiently. Conductor's approach of checking against your own project standards before you even look at the code could meaningfully reduce review time.

Where Emdash Wins

Emdash's YC W26 backing and 20,000+ downloads put it in a different position than the other two. It is building toward a full agentic development environment, not just a parallel agent runner. The Kanban view, issue tracker integration, and CI visibility suggest Emdash wants to replace your project management tool, not just sit alongside it.

Decision Framework

Frequently Asked Questions

What is a parallel agent orchestrator?

A desktop application that runs multiple AI coding agents simultaneously, each in its own isolated Git worktree. The orchestrator manages worktree creation, agent sessions, and provides a unified interface for reviewing diffs and merging changes. Superset, Conductor, and Emdash are the three leading tools in this category as of March 2026.

How do Superset, Conductor, and Emdash differ?

Superset is an open-source terminal (Apache 2.0) that works with any CLI agent. Conductor is a Mac-only app (Apple Silicon) from Melty Labs (YC S24) with deep Claude Code integration and automated code review. Emdash is an open-source desktop app (YC W26, MIT license) supporting 22+ agents with built-in Linear, Jira, and GitHub integration. Emdash is the only one available on Windows and Linux, and the only one with SSH remote support.

Do I need Git worktrees for parallel coding agents?

Git worktrees are the standard isolation mechanism. A worktree creates a separate working directory linked to the same repository, avoiding the overhead of a full clone. All three tools manage worktrees automatically. You can also manage worktrees manually with git worktree add, but these tools automate creation, cleanup, and provide dashboards on top.

Are these tools free?

All three orchestrators are free. You pay for the underlying AI agent subscriptions (Claude Max at $100-200/mo, ChatGPT Plus at $20/mo, etc.). The orchestrator adds no marginal cost. Superset is Apache 2.0, Emdash is MIT, and Conductor is proprietary but free to use.

Can I run more than 10 agents simultaneously?

The limit is your machine's resources, not the tools. Each worktree requires disk space for tracked files, and each agent session consumes memory and CPU. Practically, 5-10 agents is typical on a laptop. With Emdash's SSH remote support, you can run agents on a dev server with more resources.

How do these tools relate to Claude Code Agent Teams?

Claude Code's Agent Teams coordinate sub-agents within a single Claude session, with shared task lists and inter-agent messaging. Superset, Conductor, and Emdash operate at a higher level: they manage multiple independent agent sessions (which could each be running Agent Teams internally). The two approaches are complementary, not competing.
