Key Takeaways:

🚀 Freebuff is a terminal-based AI coding agent built on the Codebuff platform.
💸 It stays free by showing text ads inside the CLI instead of charging a subscription.
🛠️ Installation is simple: run `npm install -g freebuff`, then launch it inside your project with `freebuff`.
🤖 Freebuff uses multiple models for different tasks, including DeepSeek, Kimi, Gemini, and optional GPT-5.4 support.

🔍 Useful workflow features include file mentions, agent mentions, bash mode, chat history, knowledge files, and theme toggling.
🔐 Privacy matters: some models may collect data for training, so you need to choose carefully for private code.
📊 Freebuff is a good free alternative, while GLM Coding Plan and Verdent are strong paid options with different trade-offs.
👍 Overall, Freebuff is an interesting ad-supported coding agent worth trying if you want a free terminal assistant.

Freebuff is a free AI coding agent that runs in the terminal and is funded by in-CLI text ads instead of subscriptions. It is built on the CodeBuff platform and features nine specialized sub-agents (file picker, code reviewer, browser use, etc.), file mentions, bash mode, web research, and optional ChatGPT deep thinking integration. It supports multiple models including DeepSeek and MiniMax variants, with different models handling different workflow stages. Key caveats include limited country availability, cloud backend dependency, and privacy concerns with certain DeepSeek models that collect training data. The recommended workflow is install via npm, start with low-risk tasks, and use the /interview, /plan, implement, /review flow for larger features. Two paid alternatives are also briefly covered: the GLM coding plan (~$18/month) and Verdant for professional multi-agent workspaces.
