Cloudflare Workers: simple definition, costs and use cases

In brief

Cloudflare Workers is a serverless edge execution platform: your JavaScript/TypeScript code runs on Cloudflare's servers around the world, close to your users, with no server to manage. It's an alternative to AWS Lambda, often cheaper and faster for content served on 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.
• A single provider for compute (Workers), storage (R2, D1) and AI (Workers AI).
• Entry cost: free plan, then 5 $/month for most production use cases.

The problem, concretely

Your application needs APIs, server logic, storage: hosting that on a classic server is expensive and requires management; on AWS, egress blows up the bill 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 exit fees.

What Cloudflare Workers includes

• Workers: running functions at the edge (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 SMB

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

Why it matters for you

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