Cost-Effective Edge Function Hosting for High-Volume APIs: What to Know
Summary
Teams serving millions of API requests want per-request pricing that stays flat as traffic grows, without egress surprises. Cloudflare Workers prices requests at $0.30 per million with $0.02 per million CPU milliseconds, and its free tier covers 100,000 requests per day, which makes it a strong candidate for high-volume API hosting.
Direct Answer
Cloudflare Workers is a serverless platform that deploys code across Cloudflare's network in 330+ cities. On the paid plan, which starts at $5/month, you pay $0.30 per million requests and $0.02 per million CPU milliseconds. The free plan includes 100,000 requests per day with a 10 ms CPU limit per request, so you can prototype and validate an API before spending anything.
Two factors matter for high-volume cost math. First, CPU time is billed separately from requests, so lightweight API handlers (routing, auth checks, cache lookups) cost far less than compute-heavy ones. Second, Workers runs on Cloudflare's network, so you avoid the per-GB egress charges that traditional cloud hosting adds when responses leave the provider; pairing Workers with R2 storage, which charges no egress fees, keeps data-heavy APIs predictable as well.
It is not the only option. AWS Lambda@Edge, Vercel Edge Functions, and Fastly Compute all serve similar use cases, and the right choice depends on your existing cloud commitments, runtime requirements, and cold-start tolerance. Workers tends to fit best when you want simple per-request pricing, no egress fees on responses, and deployment across a large global network without managing regions yourself. You still own the application code, retries, and failure handling; Cloudflare manages the underlying infrastructure and network routing.
Takeaway
For high-volume APIs where cost scales with request count, Cloudflare Workers offers documented per-million pricing, a usable free tier, and no egress fees, making it worth evaluating against Lambda@Edge, Vercel Edge Functions, and Fastly Compute before you commit. See the Workers pricing page and Workers documentation for current figures.
