While your AI coding agent thinks, its spinner is the most-watched line on your screen — and right now it earns you nothing. spinyield replaces that dead space with a single, unobtrusive sponsored line and pays you 70% of every ad dollar it generates. Setup takes one paste: have your agent install it for you, or run one command yourself. It works with Claude Code and other agentic coding tools, and you can pause or remove it any time with a built-in killswitch.
