Cloudflare Pricing (2026) — Workers, KV, R2, D1 & Queues
Cloudflare's developer platform is one $5/month Workers plan plus usage-based pricing on five products. The base plan is cheap; the surprise bills come from misconfigured loops in KV writes, R2 Class A ops, or D1 scans. Each guide below has the official rates, the traps that inflate bills, and a free calculator to model your own usage — then FlareLog watches the real thing in real time.
Cloudflare Workers
Cloudflare Workers pricing explained: $5/mo Paid plan, $0.30 per million requests, $0.02 per million CPU-ms with 30M included. Free-tier daily limits, real cost examples, and a free calculator.
Cloudflare Workers Logs
Workers Logs moves from per-event to per-GB pricing on December 1, 2026: 50 GB + 10 GB-month included, $0.25/GB ingested, $0.10/GB-month stored. Calculator shows whether your bill goes up.
Cloudflare Workers KV
KV reads $0.50/M, writes $5.00/M (10x trap), storage $0.50/GB-month. Free-tier daily caps, why write-heavy caches spike bills, + free calculator and real-time burn alerts.
Cloudflare R2
Cloudflare R2 pricing: $0.015/GB-month storage, Class A ops $4.50/M, Class B ops $0.36/M, and zero egress fees. Free tier: 10 GB + 1M/10M operations. Infrequent Access rates included.
Cloudflare D1
Cloudflare D1 pricing: 25 billion rows read/month included, then $0.001 per million. 50M rows written included, then $1.00 per million. Storage $0.75/GB-month after 5 GB. How row billing actually works.
Cloudflare Queues
Cloudflare Queues pricing: 1M operations/month included, then $0.40 per million. Each message costs ~3 operations (write, read, delete). Retention, retries, batching, and the real cost-per-message math.
