Cloud cost anomaly alerts for indie developers and small teams

Problem

A developer usually paid about $30/month on Cloudflare but suddenly got a $161 container memory charge and had to ask support for a refund; many founders lack fine-grained visibility into usage-based resources and only notice spikes after the invoice arrives.

Solution

A lightweight side service that pulls billing data daily via provider APIs or exported files, breaks costs down by service and resource, and sends email/Telegram alerts when any item exceeds its historical baseline or budget threshold, with hints on likely resource attribution.

Users

Indie developers, small teams, and startups using usage-based services like Cloudflare, Vercel, Fly.io, and AWS.

MVP

Support Cloudflare and Vercel billing ingestion; build per-project/service baselines and detect anomalies; email and Telegram alerts; simple note field to attribute cost items; store no business code or sensitive data.

Revenue

Subscription per monitored cloud account: $5/month personal, $19/month team; advanced bill optimization suggestions as a premium tier.

Why now

Usage-based pricing and AI container workloads make cloud bills more volatile, while indie developers are cost-sensitive and lack simple guardrails; one person can quickly integrate multiple open billing APIs.
