vercel-cost-guard

Audits Next.js/Vercel projects for 22 cost-causing patterns across bandwidth, compute, invocations, and image optimization. Scans for large uncompressed media, missing preload attributes, API routes without caching, AI streaming without timeouts, database N+1 queries, unscoped middleware, accidental dynamic rendering, payload limit violations, missing ISR/static generation, and configuration issues. Use when reviewing a Next.js project for cost issues, preparing for launch, or after receiving an unexpected Vercel bill.
