SHOW HN: A usage circuit breaker for Cloudflare Workers
Summary
The Show HN presents a self-contained usage circuit breaker for Cloudflare Workers to prevent billing overages by monitoring internal resource usage and gracefully degrading before limits are reached. The approach uses per-resource thresholds with hysteresis, fail-safes for monitoring outages, and deduplicated alerts, and has been tested in production for two weeks with positive results.
