V8 isolate runtime at the edge. The foundation every other Cloudflare service is built on. 100k req/day free; unlimited on Paid.
Static site hosting with global CDN and automatic Git deploys. Unlimited sites, 500 builds/month free. Full-stack via Pages Functions.
Serverless SQLite at the edge. Native Workers binding, migrations, batch operations, and JSON columns. The default database for 2nth.
Eventually-consistent global key-value store. Read-optimised for low-latency global reads. Not suitable for rate limiting or counters.
S3-compatible object storage with zero egress fees. Presigned URLs, multipart upload, public buckets. Never pay bandwidth costs for blobs.
Serverless inference on 50+ models including Llama, Mistral, Whisper, and embedding models. JSON schema enforcement for structured output.
Observability and control plane for all AI calls — Claude, OpenAI, Workers AI. Token metering, request logging, semantic caching, rate limiting, fallback routing.
Vector database native to Workers. Store embeddings, query by ANN similarity, filter by metadata. Powers the RAG pipeline for skill retrieval.
Globally unique stateful compute. Each DO instance has private storage and a single-threaded execution model. The primitive for WebSockets and real-time coordination.
Reliable message queues with automatic retry and dead-letter queue. Decouple AI inference from request handlers to avoid timeout errors.
Durable multi-step execution with per-step retry, persistent state, and sleep. Orchestrate long-running AI pipelines that survive Worker restarts.
Connection pooler between Workers and external Postgres/MySQL databases. Eliminates per-request connection overhead for client SOR integrations.
Columnar time-series store built into Workers. 10M data points free/month. The token economy metering layer — cheaper and more appropriate than KV counters.
Route inbound email to Workers for processing. Send outbound via MailChannels. Parse MIME, extract attachments, trigger AI workflows from email.
Expose local or on-premise services through Cloudflare's network without opening firewall ports. Secure outbound-only connector for client SOR access.
