Angy is an open-source fleet manager and IDE for Claude Code, Anthropic API and Gemini API. Single-agent tools often generate code that fails at integration. Angy fixes this by orchestrating a deterministic multi-phase pipeline (Plan → Build → Test) featuring an adversarial Counterpart agent that strictly verifies all code. Using Git worktree isolation, multiple agents can build on your repo in parallel without branch conflicts.
Exploring Angy? Check out multi-agent friendly tools like Cursor, Claude Code and Warp for deep-context coding and agent orchestration, plus Google Antigravity to run several agents in one IDE, and Replit for rapid idea‑to‑app builds.
