 ### Backend
 
-The backend consists of a primary Express and Socket.io server, and 3 Cloudflare Workers microservices for the D1 database, R2 storage, and Workers AI. The D1 database also contains a [service binding](https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/) to the R2 storage worker. Each open sandbox instantiates a secure Linux sandboxes on E2B, which is used for the terminal and live preview.
