This repository contains the source code for Superset, a macOS desktop application that lets you run multiple AI coding agents at the same time from a single dashboard. AI coding agents are programs like Claude Code, OpenAI Codex, Cursor, and Gemini CLI that can read and write code in a terminal. Normally you can only work with one at a time, and each agent needs its own working copy of your project. Superset manages that juggling for you. The core idea is worktree isolation. When you give Superset a task, it creates a separate working directory for that task by using a Git feature called worktrees, which lets multiple branches of a project coexist on disk simultaneously. Each agent gets its own isolated copy, so several agents can work on different parts of a project at once without interfering with each other. You monitor all of them from one place. The interface includes a built-in diff viewer so you can inspect what each agent changed without opening another application, and one-click handoff to open any workspace in your usual code editor or terminal. You can configure setup and teardown scripts that run automatically when a workspace is created or deleted, which handles things like copying environment files or installing dependencies for each agent task. Superset works with any command-line coding agent, not just a fixed list. The README lists Claude Code, OpenAI Codex, Cursor, GitHub Copilot, Gemini CLI, and others as fully supported, and notes that anything runnable in a terminal should work without extra configuration. The app is currently macOS only, Windows and Linux builds are listed as untested. It is built with TypeScript using the Bun runtime and requires Git 2.20 or later. The source code is open and includes a local development setup that uses Docker for a local database.
