# InboxFly

> Self-hosted email forwarding manager for Cloudflare Email Routing. Open source (MIT), runs entirely in the user's own Cloudflare account on the free tier: routing rules that mirror Cloudflare's native UI, full mail copies (HTML + raw MIME + attachments) in the user's own R2, advanced filtering, delivery stats, 10 languages. InboxFly is a management layer on top of Cloudflare Email Routing — it does not replace Cloudflare and stores nothing outside the user's account.

InboxFly fills the gap left by Cloudflare Email Routing's free forwarding: a real management panel. Mail flows through Cloudflare Email Routing into a Worker in the user's own account; revoking InboxFly's API access does not stop the forwarding pipeline. The project site documents the self-hosted edition; a hosted Cloud edition with AI analysis is planned.
