The named attachment (conventionally STORAGE) giving a Worker scoped access to one bucket. Bindings keep storage access declarative and auditable per project.

Cloudflare R2 Object Storage
S3-compatible blob storage with no egress fees, bound to Workers for uploads, images, and media. Generated apps get private browser routes and smoke checks, not raw credentials.

A time-boxed link granting private-file access without exposing the bucket. Uploads stay private; sharing stays possible; nothing leaks by default.
Project Secrets & Env Status
Safe key-presence checks and derived-variable application for projects. Agents request missing values explicitly; secrets land in project environment, never in chat logs or code.
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.
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.
Dispatch Namespace
The isolate group containing a fleet of per-project Workers. Namespaces let one platform deploy, version, and route user projects independently.
