Forency — 网站技术取证

检测任意网站背后的技术栈：CMS、电子商务、JavaScript 框架、分析、CRM、营销自动化、支付、聊天、CDN 和托管。首先为 AI 智能体（MCP 服务器）打造，其次为人类（REST API + playground）。

为什么

BuiltWith 的 API 起价为 $295/mo，Wappalyzer 为 $250/mo，而且两者都没有提供 MCP 服务器。Forency 覆盖了真正驱动潜在客户开发和竞争研究的 ~100 项技术，免费起步，最高 $49/mo。

技术栈

层

选择

应用

Next.js 16（App Router、TypeScript、Tailwind 4），运行于 Vercel

检测

自研引擎，基于源自 webappanalyzer（GPL-3.0）的精选指纹集

数据库

通过 Prisma 7 使用 Postgres（Neon）

认证

Auth.js v5 — GitHub + Google

计费

Stripe Checkout 订阅 + webhook

MCP

packages/mcp — TypeScript、stdio，发布到 npm

布局

app/
  page.tsx              landing + free playground
  pricing/ docs/ dashboard/
  api/
    v1/lookup   POST {url}   → metered, Bearer key
    v1/batch    POST {urls}  → up to 25 URLs
    scan        playground (no key, 3/day per IP)
    key         issue/rotate a user's API key
    stripe/     checkout · portal · webhook
    auth/       Auth.js handlers
lib/
  engine/       detect.ts · curated-list.ts · custom-patterns.ts · fingerprints.json
  api-auth.ts   key auth + atomic monthly metering
  plans.ts keys.ts prisma.ts stripe.ts
packages/mcp/   the published MCP server
scripts/
  build-fingerprints.ts   regenerate fingerprints.json from upstream
  eval-engine.ts          detection accuracy harness (25 known sites)
  test-funnel.ts          end-to-end: key → free tier → 429 → upgrade
  test-mcp.ts             drives the MCP server over stdio

本地开发

npm install
cp .env.example .env          # fill in the values

# local Postgres
docker run -d --name forency-pg \
  -e POSTGRES_USER=forency -e POSTGRES_PASSWORD=forency -e POSTGRES_DB=forency \
  -p 5433:5432 postgres:16-alpine

npx prisma migrate dev
npm run dev

验证

npx tsx scripts/eval-engine.ts              # detection accuracy (25/25 expected)
npx tsx scripts/eval-engine.ts example.com  # scan one site, full JSON

# with the dev server running:
npx tsx scripts/test-funnel.ts              # billing funnel end to end
cd packages/mcp && npm run build && cd ../..
npx tsx scripts/test-mcp.ts                 # MCP server over stdio

刷新检测

lib/engine/fingerprints.json 是一份内置快照（vendored snapshot）。要拉取上游更改或添加新技术，请编辑 lib/engine/curated-list.ts，然后运行：

npx tsx scripts/build-fingerprints.ts

如果某个精选名称在上游不存在，脚本会直接报错并给出近似匹配建议。上游检测效果不佳的 Tier-1 技术，会在 lib/engine/custom-patterns.ts 中通过 overlays 进行覆盖。

许可证

应用代码：MIT。检测模式源自 webappanalyzer（GPL-3.0），仅在服务端使用；它们不会在 npm 包中重新分发。
