Start from the task rather than a product name. The Skill's decision table maps needs like APIs, uploads, background jobs, or document search to products such as Workers, R2, Queues, Workflows, or AI Search, then loads the relevant reference for implementation.

Use Workers with Workers Static Assets for all new static sites, SPAs, and full-stack apps. Workers can do everything Pages can do and is recommended for new projects; preserve existing Pages deployments only during unrelated maintenance.

Choose based on data shape: D1 for relational SQL records, KV for read-heavy key-value data, R2 for large objects and uploads, Durable Objects for per-entity coordination, and Artifacts for versioned file trees. The storage options comparison guides the tradeoffs.

Yes. Use the Agents SDK for stateful agents with tools and scheduling, Workers AI for managed model inference, Vectorize for custom retrieval, and AI Gateway for analytics and request controls. Dynamic Workers or Sandbox provide code execution runtimes.

Use Snippets for simple request or response modifications under 5ms CPU time and 32KB code size, included on paid plans. Choose Workers when you need complex logic, more subrequests, npm dependencies, or bindings like KV, D1, and R2.

TCP sockets allow at most 6 concurrent connections per request, block Cloudflare IPs, localhost, and port 25, and must be created inside a request handler. For PostgreSQL or MySQL, use Hyperdrive instead for connection pooling and caching.
