About GhostRelay
GhostRelay is a free, self-hosted email aliasing tool designed to protect your inbox and enhance your digital privacy. Created by developer Shivansh Goel, GhostRelay allows you to generate unlimited masked email addresses leveraging Cloudflare's free tier. By assigning a unique email alias to every service you use, you can instantly shut down or kill an alias the moment it becomes compromised or starts receiving spam.
Unlike traditional email forwarding services that require a Virtual Private Server (VPS), containerization like Docker, or expensive monthly subscriptions, GhostRelay eliminates ongoing server costs entirely. It can be self-hosted in roughly 15 minutes with no server required. Released under the open-source MIT license, GhostRelay provides modern aliasing features including per-alias stats, expiring aliases, and the ability to reply anonymously from any alias.
