Kosmos

Kosmos is a free, open-source AI agent management tool for Mac and Windows. It helps people turn separate AI agents, tools, and tasks into an organized workforce that can collaborate toward shared goals. Through a visual interface, users can create agents by describing what they need in plain language, without coding or using a terminal, then oversee their work from one place.

Kosmos supports the flow of work from planning and research to execution and review. Users can assign larger projects, have agents divide work into tasks and operate in parallel, and provide input when a decision is needed. A shared view shows what each agent is doing and what needs attention. Kosmos works with users’ existing AI subscriptions or API keys, including Claude, GPT, Gemini, Grok, and Muse; agents run on the user’s computer and use the chosen AI provider. The product is available for macOS with Apple M1 or later and Windows 10 or later, with installation options including downloads and a terminal command for Mac.
