Cloudflare Workers uses V8 Isolates instead of containers — no cold starts, global edge deployment, and direct access to D1, R2, KV, and AI via Bindings. Great for APIs, SSR, and lightweight backends; not suited for long-running tasks.
Hono is a web framework designed specifically for edge runtimes like Cloudflare Workers, Deno, and Bun. It's an order of magnitude lighter than Express, natively supports Web Standard APIs, and is the go-to choice for edge environments.
Upgraded action-maker from hardcoded mock data to live Cloudflare Workers AI generation. The architecture splits into Worker (AI only), Server (data storage), and Frontend (orchestration). Hit two gotchas along the way: Qwen3's thinking block and the Workers AI response format.
A climbing community platform where the web app, mobile app, and AI Q&A all run on Cloudflare — no dedicated servers.
A dynamically composable RAG pipeline built on Cloudflare Workers AI (gemma-3-12b-it + bge-m3): 14 base steps + 6 LangGraph-specific nodes, with three strategy graphs (Baseline / Agentic / Plan-Execute) selected at runtime.
