FastGPU is a live price comparison for cloud GPUs. It tracks H100, H200, B200, A100, RTX 4090, MI300X and other GPUs across marketplaces, neoclouds and hyperscalers, cheapest first, and tells you which GPU setup can run your AI job. For larger orders, capacity holders quote on a described cluster next to the live public price. Free for buyers, with a free REST API (https://fastgpu.co/docs) and a remote MCP server (https://fastgpu.co/api/mcp) for AI agents.
