I Built an AI Agent Tool Marketplace on a Static Site (It Costs Almost Nothing)

If you are building with AI agents, you have probably hit this wall: your agent needs tools but finding them means digging through GitHub repos and random blog posts. There is no npm for AI agent tools. That is the problem I set out to solve with TutuoAI , a marketplace for AI agent tools. We now catalog 116 products (38 paid, 78 free), and the entire thing runs on a static site architecture that costs almost nothing to operate. The Discovery Problem AI agents are only as good as the tools they can access. Tool discovery is a mess: For developers : You Google AI tools, get 50 listicles, spend hours evaluating For agents : No machine-readable catalog exists For tool builders : Hard to get discovered The Architecture: Why Static Wins S3 + CloudFront serves pre-rendered HTML pages.
