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.
