Orca

Orca is an open-source (MIT) desktop IDE for building with coding agents. Users run Claude Code, Codex, Gemini, OpenCode, Goose, Amp, Cursor, Droid, Kimi, and 15+ other CLI agents side-by-side — each isolated in its own git worktree and tracked in one pane-based workspace. Ships with Ghostty-inspired multi-pane terminals, built-in source control and diff review, GitHub PR/Actions integration, per-worktree browser + Design Mode (click any UI element into an agent's chat), hot-swap for multiple Codex accounts, and the Orca CLI (agent-addressable control over the IDE itself). Available for macOS, Windows, Linux. 1.5k GitHub stars at time of enrichment; no subscription required (BYO agent auth).
