Start from the task rather than the product: the Skill's decision table maps needs like uploads, background jobs, or search to products such as R2, Queues, or AI Search. When similar products fit, compare data shape, consistency, coordination, and execution lifecycle requirements.

Use Workers with Workers Static Assets for all new sites, SPAs, and full-stack apps, since Workers can do everything Pages can. Preserve existing Pages deployments during unrelated maintenance, and follow the migration guide when moving a Pages project to Workers.

D1 is a managed relational SQL database, KV is read-heavy eventually-consistent key-value storage, R2 stores large objects by key, and Durable Objects provide strongly-consistent per-entity coordination with co-located storage. Choose based on data shape and consistency requirements.

Yes. Workers AI provides managed model inference, AI Search offers managed retrieval-augmented generation, Vectorize supports custom semantic search, AI Gateway adds observability and caching, and the Agents SDK builds stateful agents with tools and scheduling.

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, bindings like KV or D1, or npm dependencies.

Cloudflare limits, prices, compatibility flags, and product availability change over time, and some products like Artifacts are in closed beta. The Skill instructs agents to verify current documentation before promising a product fit.
