Vercel Bill Sentinel

Get alerted before bot traffic explodes your cloud bill

Problem

A developer's Vercel bill jumped 10x not from user growth but from over 1M requests by meta-externalagent hitting a preview deployment. They never worried about bot traffic before and had no alerting, so they only found out when the bill arrived.

Solution

A lightweight monitoring service that connects to platform event logs, tracks bot traffic share and request spikes, alerts via email or chat before costs spike, and suggests blocking rules.

Users

Indie developers, small SaaS teams, frontend teams deployed on Vercel/Netlify

MVP

Connect to Vercel logs or Web Analytics API; identify common bot traffic by UA/IP; set request-spike threshold alerts; daily bot traffic report; generate Vercel Firewall rule suggestions

Revenue

Free tier plus per-site subscription, or charge per alert

Why now

AI crawlers and preview deployments make bill surprises common, and platform-native alerts are too coarse
