Freebuff is a free AI coding agent that provides five products for coding, building, and research with specialized agents and a choice of leading models. It requires no subscription, credits, or API key, and is supported by text ads.
Project overview
It removes the usual subscription, credit, and API-key barriers to leading AI coding models by running specialized multi-agent workflows funded through text ads, and it can be installed and run in any project from the terminal.

Best for
Developers and general users who want to code, build, or research with leading AI models without subscriptions, credits, or API keys.
Key capabilities
Specialized agents gather context, plan, edit or research, run tools, and review results instead of routing every task through one model and one prompt.
Run Freebuff in any project from the terminal; it finds the relevant files, makes changes, and runs the checks that matter for your project.
Limitations and risks
Freebuff relies on an external service boundary: Freebuff's hosted model catalog and agent service handle prompt/trace processing and serve ads, so tasks are not processed entirely locally.
Getting started
Run npm install -g freebuff, change into a project directory (for example cd ~/my-project), run freebuff, and describe what you want. Setup is easy: a single npm global install then run in any project, while desktop and hosted products require no install beyond download.
