superset

Superset is a desktop app for running a swarm of coding agents at once. Instead of babysitting one Claude Code or Codex session in a terminal, you point it at your repo and it launches ten or more agents in parallel, each isolated in its own Git worktree so they do not step on each other. It bundles a terminal, a diff viewer, and open-in-editor workflows so you can review what each agent did without juggling a dozen windows.

The model is simple: every task gets a clean worktree, the agent works, and you review the diff before you merge. It works with any CLI agent, so you are not locked to one vendor's tool. For someone already trying to run several agents by hand, this is the orchestration layer that makes it manageable instead of chaotic.

It is free to download, but read the license before you build on it. Superset ships under the Elastic License 2.0, which is source-available, not open source. You can see the code and use the app, but the license restricts offering it as a competing service. It is macOS only right now, with no Windows or Linux builds yet. Solo developers and small teams running agent-heavy workflows are the audience. Running a single agent at a time? You do not need this.

The catch is the license and the platform limits. Source-available is not the same as open source, so do not treat it like an MIT project when you plan around it. And until Windows and Linux builds land, this is a Mac-only tool.
