Bill Spike Finder

A new tool called Bill Spike Finder reviews a web app's code and configuration to identify loops and repeated work that drive up costs on Vercel, Turso, Cloudflare Workers and D1, and paid AI APIs. The tool targets causes including two schedulers on one job, uncapped retries, self-triggering work, client polling, React render loops, caches cleared on every write, middleware running on every static file, queues that resend failures indefinitely, image settings that multiply transformations, health checks that count whole tables, alerts sent on every run, and bots crawling endless filter URLs. Bill Spike Finder counts runs per month, names the billed unit, ranks issues by cost, and gives the change that stops each one.

Finds the loops behind a bill spike or an unexpected bill. Reviews a web app's code and config for loops and repeats that run up the bill on their own on Vercel, Turso, Cloudflare Workers and D1 and paid AI APIs. Finds two schedulers on one job, retries without a cap, work that triggers itself, client polling and React render loops, caches cleared on every write, middleware running on every static file, queues that resend failures forever, image settings that multiply transformations, health checks that count whole tables, alerts sent on every run and bots crawling endless filter URLs. Counts the runs per month, names the billed unit, ranks by cost and gives the change that stops each one. Use when asked why a Vercel, Turso or Cloudflare bill jumped, to find an infinite loop or a runaway cost, or to review a cron job, webhook, queue consumer, middleware or polling code before it ships.
