Everyone's talking about AI agents right now, but most tutorials stop at "call an LLM in a loop." If you actually want an agent that runs unattended — fetches data, thinks about it, writes content, and publishes it — you need a real backend, not just a prompt. This post walks through the architecture I use for exactly that: a scheduled agent that finds fresh data, drafts social posts with Claude, and publishes them, built entirely on Hono.js running on Cloudflare Workers.
I'll use "post finance news to LinkedIn/Reddit" as the running example, but the pattern generalizes to any "watch → think → act → publish" agent.
Why Hono.js for agent backends
Hono is a small, fast web framework that runs on Cloudflare Workers, Deno, Bun, and Node. For agent workloads specifically, three things make it a good fit:
Native Cloudflare Cron Triggers — agents that run on a schedule don't need a separate job scheduler or a always-on server.
