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

Superset is an open-source agentic IDE from YC P26 that allows developers to run multiple coding agents in parallel across different git worktrees and remote machines. The platform evolved from a git worktree manager into a full IDE that handles state management, task tracking, and PR workflows for agents. The team is expanding functionality with Remote Workspaces, CLI improvements, and mobile support.
