Inspired by a V2EX post, a developer spent an entire night building getcheapai.com, an AI gateway price comparison website, for only 73 yuan. During development, the author leveraged AI tools to boost efficiency: primarily using Claude Code + Sonnet 4.5 for coding, designing the interface with v0.dev, and perfectly implementing the UI effects with Opus 4.5. This tool addresses the pain point of AI users searching for cost-effective gateways, helping them save money by comparing prices across different platforms. The article shares detailed insights into the development process, technology choices, and cost breakdown, offering practical guidance for developers looking to rapidly build products using AI tools. This case demonstrates how AI tools can be used to develop other AI tools, showcasing the immense potential of current AI technology in real-world applications.
