Vercel Doctor
A skill and toolkit that lets coding agents diagnose and fix patterns that inflate your Vercel bill on Next.js projects.
Overview
Vercel Doctor packages review guidance agents can run after changes to catch cost-heavy patterns early — oversized functions, cache misuse, image handling, and similar footguns.
It is designed as an installable skill for Cursor and other agent workflows, not a standalone SaaS dashboard.
The problem
Vercel's pricing model rewards efficient compute, but Next.js apps easily accumulate expensive defaults: unbounded ISR, large server bundles, missing image optimization, and Fluid Compute misconfiguration.
Developers often discover bill spikes after deploy, when fixes are reactive and stressful.
Wins
Published as open source with clear, agent-consumable rules so reviews run automatically in CI and local dev.
Gained traction in the OSS community as a practical guardrail for Vercel-hosted Next.js apps.
