When to use

适用场景

  • User asks "what tech stack does [website] use?"
  • User says "build me something like [website]" — analyze it first
  • User wants to compare tech stacks of different sites
  • User needs to understand a competitor's technical choices
  • 用户询问“[某网站]使用什么技术栈？”
  • 用户提出“帮我构建一个类似[某网站]的应用”——先对其进行分析
  • 用户想要对比不同网站的技术栈
  • 用户需要了解竞争对手的技术选型

Prerequisites

前置条件

Requires Node.js >= 20. Install if not present:

Analyze a website

分析网站

bash
unbuilt <url> --format agent
Always use 
--format agent
— it returns compact one-line-per-category output optimized for your context window.
Example output:
Framework: Next.js
UI: React
Bundler: Webpack
Styling: Tailwind CSS + PostCSS
State: Zustand
Tables: TanStack Table + TanStack Virtual
Components: Radix UI
Animation: Framer Motion
Router: Next.js Router
Monitoring: Sentry
bash
unbuilt <url> --format agent
请始终使用 
--format agent
参数——它会返回紧凑的分类单行输出，适配你的上下文窗口。
示例输出：
Framework: Next.js
UI: React
Bundler: Webpack
Styling: Tailwind CSS + PostCSS
State: Zustand
Tables: TanStack Table + TanStack Virtual
Components: Radix UI
Animation: Framer Motion
Router: Next.js Router
Monitoring: Sentry

Alternative output formats

可选输出格式

Only use these if the user explicitly asks for more detail:
  • --json
    — full structured JSON with confidence scores and matched patterns
  • No flag — default table output with all categories
仅当用户明确要求更详细内容时使用以下格式：
  • --json
    —— 返回包含置信度分数和匹配模式的完整结构化JSON
  • 无参数——默认返回包含所有分类的表格输出

Remote analysis

远程分析

If Playwright fails or takes too long:
bash
unbuilt <url> --remote --format agent
Uses unbuilt.app servers with cached results.
如果Playwright运行失败或耗时过长：
bash
unbuilt <url> --remote --format agent
使用unbuilt.app服务器的缓存结果进行分析。
