Cloudflare Workers: simple definition, costs and use cases

In short

Cloudflare Workers is a serverless edge execution platform: your JavaScript/TypeScript code runs on Cloudflare servers worldwide, close to your users, with no server to manage. It is an alternative to AWS Lambda, often cheaper and faster for content served over the Internet.

• Low latency everywhere: the code runs at the edge, not in a single region.
• No egress fees: getting data out of Cloudflare is free, unlike AWS.
• One provider for compute (Workers), storage (R2, D1) and AI (Workers AI).
• Entry cost: free plan, then $5/month for most production uses.

The problem, concretely

Your application needs APIs, server logic, storage: hosting that on a classic server is costly and managed; on AWS, egress makes the bill explode as soon as content is served to users. Cloudflare Workers runs your code at the edge, with a cost proportional to real usage and no egress fees.

What Cloudflare Workers includes

• Workers: edge function execution (APIs, webhooks, middleware).
• R2: file storage, replaces S3 without egress fees.
• D1: serverless SQL database at the edge.
• Workers AI + Vectorize: AI and vector search at the edge.
• Durable Objects: shared state and real-time.

How much it costs for an SME

The free plan covers a prototype. In production, most SME apps run for $5 to $20/month ($5 plan + usage). With no egress fees, unlike AWS where 1 TB of egress can cost $90.

Why it matters to you

If your application or automation needs reliable, cost-controlled APIs and storage, Cloudflare Workers is an excellent choice. I integrate this stack into your projects, at a fixed price from 440 € excl. tax, no subscription. Details on the Cloudflare Workers developer page.
