Launch HN: Superset (YC P26) – IDE for the agents era

Superset (YC P26) is a desktop application that orchestrates multiple CLI-based coding agents, such as Claude Code and Codex, across isolated git worktrees to enable parallel task execution without context switching. It provides a unified interface for monitoring agents, reviewing changes with a built-in diff viewer, and handing off workspaces to external editors or terminals. The tool is source-available under the Elastic License 2.0 and works with any terminal-based agent.

Orchestrate swarms of Claude Code, Codex, and more in parallel. Works with any CLI agent. Built for local worktree-based development. Download for macOS https://github.com/superset-sh/superset/releases/latest • Documentation https://docs.superset.sh • Changelog https://github.com/superset-sh/superset/releases • Discord https://discord.gg/cZeD9WYcV7 Superset orchestrates CLI-based coding agents across isolated git worktrees, with built-in terminal, review, and open-in-editor workflows.
