Supernova

The fast, opinionated development environment for the Pi coding agent.

Supernova is built for developers who want to move quickly without giving up control.

• Performance first — A virtualized timeline and streaming UI stay responsive, even in long sessions.
• Sleek by design — A calm, focused interface without the feature sprawl of a general-purpose agent environment.
• Pi, not a replacement — Pi remains the execution engine for models, providers, credentials, sessions, and tools.
• Git-backed navigation — Move across conversation checkpoints and restore turn-level workspace changes without moving HEAD or resetting staged work.
• Remote-first — Supernova is designed to run agents where the code lives and control them from anywhere. Remote access is coming soon.
