Connect Workers to PostgreSQL/MySQL with global connection pooling, query caching, and automatic latency reduction. \n \n Supports PostgreSQL (v9.0-17.x) and MySQL (v5.7-8.x) with node-postgres, postgres.js, and mysql2 drivers; includes Drizzle and Prisma ORM integration patterns \n Eliminates 7 connection round trips via edge pooling near Workers and connection pooling near databases, reducing latency by 90% (March 2025) \n Prevents 11 documented errors including postgres.js hangs with IP addre

Deploy remote MCP servers on Cloudflare Workers with TypeScript, OAuth, and Durable Objects. \n \n Supports SSE and HTTP Streamable transports with automatic WebSocket hibernation for stateful sessions; choose from five auth templates (no-auth, bearer, GitHub/Google OAuth, enterprise SSO) \n Base path configuration is critical—server and client URLs must match exactly (e.g., serveSSE(\"/sse\") requires client URL https://worker.dev/sse , not https://worker.dev ) \n Includes 24 documented error s

Build stateful AI agents on Cloudflare Workers with WebSockets, persistent state, scheduling, and multi-agent coordination. \n \n WebSocket-based real-time communication with automatic state synchronization across clients and devices; resumable streaming persists across disconnects and page refreshes \n Built-in SQLite storage (up to 1GB per agent), task scheduling with cron expressions, and Durable Objects for globally unique, persistent agent instances \n Multi-agent coordination via routeAgen

Store, transform, and deliver images at scale with Cloudflare Images API and URL-based transformations. \n \n Upload images via API, direct creator URLs, or external sources; serve via imagedelivery.net with optional signed URLs for private access \n Transform any image on-the-fly using /cdn-cgi/image/ parameters (resize, crop, quality, format auto-detection) or Workers cf.image object \n Create up to 100 named variants for common transformations; use flexible variants for dynamic parameters (in

Async message queues for background processing with automatic retries, batching, and dead letter queue support. \n \n Supports producer and consumer patterns with configurable batching (1-100 messages), timeouts (0-60s), and retry policies (0-100 retries) across 10,000 queues per account \n Handles non-idempotent operations safely through explicit message acknowledgement; prevents duplicate writes and data loss with dead letter queue configuration \n Processes up to 5,000 messages/second per que

Headless Chrome automation on Cloudflare Workers with Puppeteer and Playwright. \n \n Supports both Puppeteer (v1.0.4) and Playwright (v1.1.0) for screenshots, PDFs, web scraping, and browser automation on Cloudflare's global network \n Session reuse and browser context isolation for performance optimization; multiple tabs within a single browser to reduce concurrency usage \n Includes 8 documented issue preventions covering XPath workarounds, binding configuration, timeouts, concurrency limits,

Bot protection with Turnstile CAPTCHA alternative for forms, login, and signup flows. \n \n Supports implicit (auto-render) and explicit (programmatic) rendering modes, plus React integration via @marsidev/react-turnstile \n Mandatory server-side validation via Siteverify API; tokens expire in 5 minutes and are single-use only \n Prevents 15 documented issues including CSP blocking, Safari Hide IP failures, Chrome/Edge first-load errors, token reuse bugs, and Jest incompatibility \n Includes tes

Global key-value storage at Cloudflare's edge with sub-5ms latency and eventual consistency. \n \n Supports reads, writes, bulk operations, metadata storage, TTL expiration, and pagination across 1,000+ namespaces per account \n Enforces 1 write per second per key (use retry logic for rate limits) and eventual consistency within ~60 seconds across regions \n Offers cacheTtl for edge caching (minimum 60s), metadata optimization to avoid extra reads, and hot/cold key performance patterns (6-8ms vs

Production-ready Cloudflare Workers setup with Hono, Vite, and Static Assets preventing 10 documented issues. \n \n Prevents critical routing conflicts (API routes returning index.html ), export syntax errors, HMR race conditions, and Vite 8+ compatibility issues through tested configuration patterns \n Includes auto-provisioning for R2, D1, and KV resources (Wrangler 4.45+), Workers RPC for service-to-service calls, and gradual rollout asset mismatch handling \n Covers free tier 429 errors with
