HelpPuff – AI site chat your coding agent deploys to your Cloudflare

HelpPuff is an open-source, MIT-licensed AI website chat that runs entirely in your own Cloudflare account, with setup done by a coding agent such as Claude Code, Codex or Cursor from a single prompt. It learns your site and files, answers visitors, captures leads, supports live chat handoff, quotes and jobs, and in-chat booking, using Cloudflare Workers, Workers AI, D1, Vectorize, KV and Durable Objects. The default setup fits the Workers Free plan at roughly 300 AI answers a day, and HelpPuff states it has no hosted control plane and receives none of your data.
