Freebuff

Freebuff is a free coding agent that can be used through a command‑line interface and a web application, letting developers write and run code without any subscription, setup, or lock‑in. It provides daily free credits that can be spent on various AI models, and it includes desktop apps for macOS, Windows, and Linux, a cloud IDE that runs in a sandbox on any GitHub repository, and a chat feature for research‑based answers.

Because it requires no payment or credit‑card information, Freebuff enables users to run coding agents in parallel on their machines or in the cloud while keeping their projects, eliminating the need for recurring fees of competing services.
