Railcode founder builds designer-grade website with coding agents
What happened
On September 30, 2026, Hacker News' front page featured Railcode founder Yakko Majuri, who used coding agents (Claude, Fable) to repeatedly generate and filter design prototypes, producing a website visitors mistook for a designer's work. He indexed each prototype alongside its generation prompt, iterated on a roller-coaster visual through two prompt strategies he calls "intensity grading" and "letting go," and eventually expanded from a single roller coaster to a whole amusement-park theme.

Railcode 创始人 Yakko Majuri 用编码智能体（Claude、Fable）反复生成并筛选设计原型，做出了被访客误以为出自设计师之手的官网。他把每个原型连同生成提示词整理成索引，通过"强度分级"和"放飞"两类提示策略迭代过山车视觉，最终从单条过山车扩展到整座游乐园主题。
