CodebuffAI/freebuff

Freebuff is a free coding agent that provides five specialized AI products for coding, building, and research accessible through terminal, desktop, browser, and GitHub integration without requiring subscriptions, credits, or API keys.

Freebuff addresses the cost barrier to AI-assisted development by offering free access to multiple leading models through text-ad-supported products. The tool uses specialized agents tailored to different tasks rather than routing all requests through a single model and prompt. Agents gather context, plan changes, edit or research as needed, run tools, and review results. The platform includes a curated model catalog with options like DeepSeek V4 Flash, GPT-5.6 Luna, MiniMax M3, and MiMo 2.5, each optimized for different use cases. Some models have temporary usage limits due to provider cost changes, though the project indicates these restrictions are intended to be reverted.

Freebuff suits developers who want AI assistance without subscription costs and who work across multiple environments—from local terminal work to full-stack web development to GitHub repository automation. The Desktop product runs parallel agents locally, the CLI enables coding from the terminal, the Web product builds full-stack applications, Cloud connects to GitHub repositories, and Chat provides research and reasoning capabilities. The choice of multiple models with different strengths means users can select based on their specific task requirements rather than being locked into a single model's approach.

The project maintains active development across its five distinct products, each serving different workflows and platforms. The tool actively manages model availability and capacity constraints, adjusting access tiers and limits in response to provider pricing changes. The project communicates transparently about temporary restrictions and its intention to expand access as conditions allow.
