superset-sh/superset

Superset is an agentic IDE that orchestrates multiple coding agents in parallel, each running in isolated git worktrees.

The tool addresses the inefficiency of running coding agents sequentially or managing them across separate windows. It works by spawning multiple agents simultaneously—such as Claude Code, Codex, and other CLI-based tools—each in its own git worktree with isolated branches, terminals, and environments. This isolation prevents agents from interfering with each other while allowing developers to monitor progress from a single interface, compare results, and merge the best outcomes.

Superset suits developers who want to parallelize coding tasks and reduce context-switching overhead. It works best for projects where multiple independent coding approaches can be explored simultaneously, and where agents need to operate on the same codebase without collision. The tool includes a built-in terminal with tabs and splits, a diff viewer for inspecting and editing agent changes before committing, and an in-app browser for previewing dev servers. Workspaces can be accessed remotely via CLI, SDK, or MCP, and handed off to external editors when needed.

The project receives most of its issue reports from outside users rather than the core team, indicating a substantial base of real-world adopters. Responses to issues and pull requests typically arrive within one to two weeks. Work in the issue tracker centers on bugs, enhancements, and feature requests.
