Your AI assistant is recommending dead tech.
We tell it when.
Every LLM behind Claude Code, Cursor, Windsurf, and Copilot is frozen at a training cutoff months ago. They confidently recommend Webpack, Prisma, Jest, Express, Yarn — when Vite, Drizzle, Vitest, Hono, pnpm have already taken over. architectures.app is the MCP server that tells your AI which recommendations are still current — and which to replace.
Free MCP for Claude Code / Cursor / Windsurf / any MCP-compatible assistant. Real-time adoption signals from 127K+ public repos + deps.dev + GitHub Activity. REST API for builders →
One call. One freshness score. One correct alternative.
The same endpoint the MCP calls under the hood. Try any of the techs your AI assistant has been getting wrong.
