The $0 AI Coding Stack Is Here.

AI coding has acquired an interesting price tag.

Cursor. Claude Code. Codex. Devin. Another subscription, another usage limit, another line on the monthly card statement.

Now Freebuff is trying something different: give developers access to capable coding agents without charging a conventional subscription fee.

Freebuff is a free coding agent that works directly with your projects. It operates across CLI, desktop, and web environments, allowing it to inspect codebases, execute development tasks, and run a complete agentic coding workflow.

But the defining feature isn't just the agent loop itself. It is the access model: no subscription cost and no API key required for its bundled free tier.
