Markdown rendering, real-time streaming, and a familiar messaging experience.</p> <p>🐙 <strong>.octo Agents</strong><br> Define agents as simple <code>.octo</code> files. Each file is an independent agent with its own role, personality, and capabilities. Delete the file, delete the agent. Copy it, clone the agent.</p> <p>🧠 <strong>Hidden Orchestrator</strong><br> A smart orchestrator reads the context and calls the right agent at the right time. You direct, agents collaborate.</p> <p>🔗 <strong>Agent-to-Agent</strong><br> Agents @mention each other and trigger chain reactions. A developer agent asks the designer for feedback, a planner coordinates tasks — all without your intervention.</p> <p>📁 <strong>Spaces &amp; Folders</strong><br> Create multiple spaces and add folders to each. Organize different agent teams for different projects, all in one app.</p> <p>📝 <strong>Shared Wiki</strong><br> A shared knowledge base that agents and users read and write together. Decisions, notes, and context persist across sessions.</p> <p>🔐 <strong>Per-Agent Permissions</strong><br> Fine-grained control per agent. Configure file write, shell commands, and network access independently.</p> <h2> How It Works </h2> <p><strong>1. Open the app and create a space</strong><br> Launch Octopal and create a new space for your project.</p> <p><strong>2. Open a project folder</strong><br> Open any folder and it becomes your project. Agents live inside as <code>.octo</code> files.</p> <p><strong>3. Create agents and chat</strong><br> Give agents roles and start chatting. @mention them directly, or let the orchestrator handle routing.</p> <h2> Try It Now </h2> <p>Free and open source.
