Cloudflare just open-sourced an email client where an AI agent reads your inbox, drafts your replies, and absolutely won't send anything without your explicit permission.
It's called Agentic Inbox, and it runs entirely on Cloudflare Workers. No third-party servers ever touch your email.
Here's what the AI agent can actually do:
→ Read your inbox and highlight what matters → Search through all your conversations → Automatically draft replies the moment new emails arrive → Hold every draft until you explicitly confirm—it never sends on its own → Nine built-in email tools running on Workers AI
Each inbox lives in its own Durable Object with a SQLite database. Attachments go to R2 storage. Your email never leaves your Cloudflare account.
Deploy the whole system with one click. Cloudflare automatically configures R2, Durable Objects, and Workers AI.
It's Apache 2.0 licensed and 100% open source.
