What each one is
CowAgent
CowAgent is an open-source AI assistant meant to run 24/7 on a personal computer or server. It can plan multi-step tasks, use tools and skills, keep long-term memory and a knowledge base, and be reached through a web console or chat apps such as WeChat, Feishu, DingTalk, Telegram and Slack. You connect it to a model provider of your choice, such as Claude, GPT, Gemini or DeepSeek.
Horizon
Horizon is a self-hosted tool that gathers news from sources you configure and uses AI models to rank and summarize them into a daily briefing in English and Chinese. The README shows a ranked daily overview, per-story context and summaries, and notifications sent to Feishu. It is aimed at people who want a personalized news digest instead of browsing many sites.

Strengths

- Offers a one-line installer, Docker option and desktop client for different setups
- MIT licensed with a large community and active development
Horizon
- Open source under the MIT license
- Produces briefings in both English and Chinese according to its description
- Includes a live demo and a configuration guide to get started
Not ideal for
CowAgent
- Users who need a simple hosted service with no setup, since the README centers on self-hosting or a separate online option
- People who are uncomfortable giving an AI agent access to their computer and external accounts, because it can control files, terminal and browser
- Users who only need a basic chatbot, since the feature set is broad and heavier to run
Horizon
- People who want a ready-made news app with no setup, since the README centers on configuration and self-hosting
- Users unwilling to supply AI model access, because the summaries depend on LLM providers
- Anyone needing a verified news source, since output quality depends on configured sources and models
Trade-offs
CowAgent
- Broad permissions (files, terminal, browser) raise security and privacy considerations that the user must manage
- The README is truncated and does not fully document every configuration option, so confidence in details is limited
- Running it 24/7 on a server requires opening a port and setting a web password, which adds setup work
Horizon
- The README is truncated here, so detailed setup requirements are not fully visible
- Relies on third-party AI model providers whose costs and availability are outside the project's control
- Latest release is not listed, so version stability is unclear
