Overview

Open-source multi-agent orchestration framework for coordinating coding assistants into specialist software development teams.

Details

OpenCastle is an open-source multi-agent orchestration framework from MonkiLabs for coordinating coding assistants into specialist software development teams. The project provides an official website, documentation, and GitHub repository. Its architecture documentation describes a Team Lead agent that decomposes work, delegates to specialist agents, and verifies results through quality gates orchestrated by the opencastle CLI.

When to Use

Use when evaluating open-source frameworks for orchestrating multiple coding assistants. Use when exploring agent-team workflows where a lead agent delegates work to specialist coding agents. Use when you want a CLI-driven framework for software-development agent workflows.
