Orca calls itself an ADE (Agentic Development Environment), the AI orchestrator for 100x builders (75k+ stars, MIT/TypeScript, YC-backed). Central mechanism: fan one prompt across Codex, Claude Code, OpenCode and Pi, each isolated in its own git worktree, then compare results and merge the winner. Also WebGL terminals, Design Mode (click a UI element to send its HTML/CSS/screenshot into the prompt), native GitHub and Linear integration, diff annotations routed back to the agent, SSH worktrees and mobile notifications. Not benchmarked by us; graded needs-reproduction.
