A good fit for

APIs and edge logic that should run close to users
Apps with spiky traffic that want no cold starts and no capacity planning
Small projects that fit in the free plan's 100,000 requests a day
Teams already using Cloudflare for DNS, caching or storage

Not a good fit for

Long-running processes or workloads that need a full server: Workers are request-driven functions with CPU limits
Teams that want to run the same platform on their own servers: only the workerd runtime is open source, not the Cloudflare network
Code that depends on Node.js features outside the Workers runtime

About Cloudflare Workers

Workers lets you deploy a function that Cloudflare runs close to your users. Code runs in 335+ cities by default, or near your data with Smart Placement. It uses V8 isolates instead of containers, so there are no cold starts and no pre-provisioned concurrency to plan for traffic spikes.

Workers connect to other Cloudflare services through bindings, including D1 for SQL, Workers KV and Workers AI. You can develop locally with workerd, the open source runtime Workers is built on.

Billing is based on CPU time, not time spent waiting on network or storage.
