Cloudflare

Cloudflare’s developer platform runs serverless compute on V8 isolates across 300+ edge locations. For $5/mo you get Workers (compute), D1 (SQLite database), R2 (object storage), KV (key-value store), Queues, Durable Objects, Tunnels, and more. Everything deploys with npx wrangler deploy.

The platform converges around Workers as the universal compute primitive. Pages is being absorbed into Workers with Static Assets. The Vite plugin is becoming the standard DX for full-stack apps. New primitives like Containers, the Agents SDK, and Workflows keep expanding what you can build on the edge.

Learning Project: Webhook Hub

The quickstarts build toward a Personal Webhook & API Hub - a service that receives webhooks, stores them in D1, queues async delivery, and forwards to local services via Tunnels. Each quickstart adds a new Cloudflare service to this project.
