Orca is a free, open-source desktop app that runs coding agents in parallel git worktrees.
Orca runs a fleet of agents in git worktrees. Satura Space points them at a live Unity game, with four things Orca doesn't have.
The agent sets up the moment and opens Unity's real Inspector on just the fields that matter. You tune it by feel.
Run agents in parallel, each in its own side Unity project, streamed beside the game. Open a Tuner on any of them.
Up to four synced editors, each streamed with its own input. One handle call starts every player on the same frame.
Ask about anything you don't know. Drift walks you through the UI, points at the field and explains what to tweak in the Inspector.

Orca's own pages don't mention Unity or games. It runs CLI agents in git worktrees with an embedded browser. Satura Space runs Unity itself: it streams the game beside the agent and adds the Tuner, scratchpads and multiplayer testing.
Orca is free and open source under the MIT license, and you bring your own agent subscriptions. Satura Space is $19 a month, or $15 billed annually, with a 7-day trial and no card.
Satura Space needs Unity 6 with the Mono scripting backend.
Try it for seven days. No card needed.
