What is CowAgent?

What it is

CowAgent is an open-source super AI assistant and Agent Harness, distributed under the MIT license and written in Python. It is the project formerly known as chatgpt-on-wechat, and it sits in the AI & Machine Learning / AI Development Platforms category. The repository carries roughly 46,975 stars, 10,351 forks, and 24 open issues, with four years of history and a most recent push on 15 September 2026. Its homepage is cowagent.ai, and the project describes itself as lightweight, easy to deploy, and built to extend.

The concrete problem it addresses is the gap between a raw model API and a working assistant. CowAgent plans tasks and loops over tools until a goal is reached, runs tools and Skills, builds a personal knowledge base and long-term memory, forms multi-agent teams, and self-evolves through use. It treats this assembly as a reference implementation of Agent Harness engineering: messages arrive through Channels, the Agent Core plans and reasons over memory, knowledge, tools, and skills, Models generate the response, and the answer returns through the originating channel. Any major LLM provider can be plugged in, and the service runs around the clock on a personal computer or server across the web and major IM platforms.

Key capabilities

  • Planning that decomposes complex tasks, executes them step by step, and loops over tools until the goal is reached.
  • Multi-Agent teams where each Agent carries its own role, model, skills, and knowledge while collaborating in a shared conversation.
  • A three-tier memory architecture of context, daily, and core layers, with automatic Deep Dream distillation and hybrid keyword plus vector retrieval.
  • Knowledge curation that turns material into a structured Markdown wiki and an evolving knowledge graph with visual browsing.
  • Self-Evolution that reviews conversations automatically to improve skills, follow up on unfinished tasks, and consolidate memory and knowledge.
  • Skills installed in one click from Skill Hub, GitHub, or ClawHub, or created through natural-language conversation.
  • Built-in tools for file I/O, terminal, browser, scheduler, memory retrieval, and web search, plus native MCP integration.

Who uses it and how

  • Individuals running a personal assistant 24/7 on a home computer or a server, reachable from the web console and messengers.
  • Teams deploying into IM platforms including Web, WeChat, Feishu, DingTalk, WeCom, QQ, Official Accounts, Telegram, and Slack.
  • Operators installing the bundled macOS or Windows desktop client, where the backend ships included and works out of the box.
  • Server administrators managing the service through the cow CLI with start, stop, restart, status,

🏗️ Architecture

CowAgent Architecture

CowAgent is a complete Agent Harness: messages flow in through Channels; the Agent Core plans and reasons over memory, knowledge, and the available tools and skills; Models generate the response, which is sent back through the originating channel. Every layer is decoupled and independently extensible.

🚀 Quick Start

A one-line installer takes care of dependencies, configuration, and startup:

Linux / macOS:

bash <(curl -fsSL https://cdn.link-ai.tech/code/cow/run.sh)

Windows (PowerShell):

irm https://cdn.link-ai.tech/code/cow/run.ps1 | iex

Docker:

curl -O https://cdn.link-ai.tech/code/cow/docker-compose.yml
docker compose up -d

Once started, open http://localhost:9899 to access the Web console — your one-stop hub to chat with the Agent, configure models, connect channels, and install skills.

Deploying on a server? Set web_host to 0.0.0.0 in config.json to make the console reachable from outside, and set web_password to protect it. Don't forget to open port 9899 in your firewall or security group.

📖 Detailed guides: Quick Start · Install from Source · Upgrade

After installation, manage the service with the cow CLI:

cow start | stop | restart        # service control
cow status | logs                  # status and logs
cow update                         # pull latest code and restart
cow skill install <name>           # install a skill
cow install-browser                # install browser automation

💻 Desktop client: download the CowAgent Desktop client (macOS / Windows) — the backend is bundled, ready to use out of the box.


👥 Multi-Agent Team

Create a team of Agents, each with its own memory, capabilities, knowledge, and workspace. Each can focus on its own domain, or collaborate within a shared conversation to tackle complex tasks together. Multi-Agent teams are available on the Web, the desktop client, and IM channel integrations.
