agentic-inbox

agentic-inbox is an agent framework - A self-hosted email client with an AI agent, running entirely on Cloudflare Workers.

Overview

Agentic Inbox lets you send, receive, and manage emails through a modern web interface -- all powered by your own Cloudflare account. Incoming emails arrive via Cloudflare Email Routing, each mailbox is isolated in its own Durable Object with a SQLite database, and attachments are stored in R2.

An AI-powered Email Agent can read your inbox, search conversations, and draft replies -- built with the Cloudflare Agents SDK and Workers AI.
