"Orca: The Agent Development Environment for Running a Fleet of AI Coders at Once"

Quick recap: every specific feature (worktree isolation, Design Mode, SSH worktrees, GitHub/Linear integration, mobile companion, scriptable CLI, MIT license) is independently verified across multiple sources. 

The only soft spot is the exact "8.6k stars" figure — reviews from late June showed ~7,747 with strong weekly growth, so 8.6k is plausible but not independently confirmed at time of posting. The "almost nobody's solved" framing is the main fluff, since a few other parallel-agent orchestration tools exist in this space too.
