SimpleLogin

It provides a self‑hostable service that creates email aliases, allowing users to give a disposable address to websites and have messages forwarded to their real inbox while keeping the original address hidden. The system forwards incoming mail to the user’s mailbox and can also send replies from the alias, so the real address never appears to the correspondent. Users manage aliases through a web interface and can integrate the service with browser extensions for Chrome and Firefox as well as Android and iOS applications, which can be pointed at a personal server via an API URL.

The software is released under the MIT license, runs on a Linux server using Docker containers, and requires standard email infrastructure such as MX, A, and DKIM DNS records. It is designed for individuals or organizations that want to protect their online identity, reduce spam and phishing, and maintain control over their email flow without relying on a proprietary service.

Because all components are open source and free to self‑host, the solution can be deployed without subscription fees, offering a privacy‑focused alternative for anyone needing anonymous or disposable email addresses.
