Orca: An ADE Running Five Coding Agents Simultaneously, A New Parallel Orchestration Paradigm with Over 20,000 Stars on GitHub
Orca, an open-source project by Stably AI, was a trending ADE (Agent Development Environment) on GitHub Trending in July 2026. Built on Git Worktree, it provides isolated parallel runtime environments for over 30 CLI Agents including Claude Code, Codex, and OpenCode. It supports one-click Worktree creation from GitHub/Linear tasks, UI context injection via Design Mode point-and-click, as well as SSH remote Worktree. Its GitHub stars exceeded 20,000 in July and continued to rise. This article sorts out the differences between ADE and traditional IDEs, core mechanisms, installation methods and applicable scenarios, to help evaluate multi-agent parallel development solutions.

In July 2026, the open-source project Orca (stablyai/orca) topped the GitHub Trending weekly chart, with its star count exceeding 30,000. Positioned as an Agent Development Environment (ADE) rather than a traditional IDE, it allows running terminal Agents such as Claude Code, Codex, and Cursor CLI in parallel on the same interface. Each Agent uses an independent git worktree to isolate changes, and supports prompt fan-out comparison, Diff annotation review, GitHub/Linear integration, and orchestration via the Orca CLI. Based on official repository and public Trending analysis, this paper sorts out Orca's core mechanisms, functional boundaries, and selection comparisons with herdr and IDE-built-in Agents, providing reference for developers in multi-Agent parallel coding scenarios.
