CostHex is a planned monitoring service that aims to turn serverless usage into cost alerts sent through chat or email.

Landing page captured for the 2026-10-13 issue.

For: Teams running serverless apps or usage-billed APIs
Worth noticing: The page lists five bill incidents, including a $104,500 Netlify DDoS tied to a 3.44 MB MP3.

Field notes

The page describes read-only connections that would translate usage measures such as requests, CPU, and bandwidth into hourly costs, then route a spike alert to chat or email. Its incident list includes a Netlify DDoS associated with a 3.44 MB MP3 and a Firebase / Google Cloud scraper that made 116 billion Firestore reads. Early access is described as starting with Cloudflare Workers; SMS, phone calls, and one-click fixes are presented as later additions.
