Superset

Superset is a macOS code editor built around the idea that you should be running many AI coding agents at once rather than babysitting one. Each agent gets its own Git worktree so dozens of Claude Code, Cursor, OpenCode, or Gemini sessions can work in parallel without stepping on each other's branches, and the app surfaces diff review, commit history, and one-click handoff into VS Code, Cursor, Xcode, JetBrains IDEs, or a terminal.

It is aimed at developers who have already adopted CLI coding agents and are hitting the natural ceiling of one-agent-at-a-time workflows. The free tier covers a single user with local workspaces and GitHub integration; Pro is $15/user/month yearly ($20 monthly) and adds unlimited users, remote workspaces, and Linear integration; Enterprise adds SSO, audit logs, and SLAs. The companion repo at superset-sh/superset sits around 12k stars, though the product itself is distributed as a desktop download rather than something you self-host.

This is firmly a meta-tool: it does not ship its own model and brings no value if you are not already paying for (or running) an underlying coding agent. The payoff is workflow density for people who want to fan out a refactor, a bug hunt, and a feature spike across three agents simultaneously and then review the diffs side by side.
