What is AnonAddy?

AnonAddy is the code behind addy.io, an anonymous email forwarding service. Each website gets its own alias, so a leaked or spammed address can be deactivated or deleted without touching your real mailbox, and you can see which site passed your address on. Aliases can be created on the fly under a personal subdomain or your own domain once DNS records are added. Incoming mail can be encrypted with your GPG/OpenPGP key, one alias may forward to several recipients, and replies sent through an alias keep the real address hidden.

Good fit if

  • You want a separate address for every account you sign up for and the ability to cut off any of them.
  • You own a domain and want to run alias forwarding on it yourself instead of paying a hosted alias provider.
  • You want forwarded messages encrypted with your own OpenPGP key before they reach your inbox.

Look elsewhere if

  • You want a comparable alias service with a different codebase: SimpleLogin.
  • You need real mailboxes with IMAP and webmail rather than forwarding: Mailcow or Mail-in-a-Box.

Before you adopt it

The project switched from MIT to AGPL-3.0 in September 2022, so modified versions offered to users over a network must publish their source. No paid parts were found in the repository, although the hosted addy.io offers subscriptions. All commits in the last 90 days came from one author, so the project depends on a single developer. There is no Docker image or compose file in the repository, which means self-hosting involves setting up the application and its mail handling by hand.
