What is Cloudflare Worker?
Serverless code running on Cloudflare’s edge network, close to visitors worldwide. BYOB deploys generated apps as Workers: no servers to provision, scale, or patch.
Related terms
Dispatcher Worker
The SaaS router that maps each request — by publish slug or custom domain — to the right per-project Worker. One edge entry point, thousands of isolated apps behind it.
Pages Domain (byob.page)
The hosted-site suffix for BYOB projects. Every publish gets a stable address on it instantly; custom domains layer on top when ready.
One-Click Deployment
Publishing a site to production hosting without manual configuration. BYOB deploys to an edge network with rollback to known commits when a release misbehaves.
Dispatch Namespace
The isolate group containing a fleet of per-project Workers. Namespaces let one platform deploy, version, and route user projects independently.
KV Domain Map
A key-value lookup binding slugs and custom hostnames to their Workers. Custom-domain support is a map entry plus DNS — no redeploy required.
D1 Binding & Proxy Token
How apps reach their database: a Worker binding plus a server-to-server proxy token. Credentials stay in project environment, never in generated files.
