   addy.io vs Firefox Relay Comments

   Top Positive Comment by Jon_B · Apr 20, 2021

   You can have unlimited aliases with AnonAddy and not with Firefox Relay

   Positive comment by cosmospider · Apr 19, 2025

   Addy isn't a service but a hostable software. Host your own or pick an instance that isn't going to be shut down too soon, and you'll not have to depend on Mozilla's unpredictable and unhealthy will to shut down it's services.

   Positive comment by Paul · Nov 29, 2022

   Very good tool to avoid spam, with unlimited aliases.

   SimpleLogin vs Firefox Relay Comments

   Positive comment by Paul · Nov 29, 2022

   Very good tool, pretty similar to AnonAddy.

   Positive comment by Shoji VR · Jul 27, 2022

   has open source option, dark mode, free version limited to 10 masks and 25MB email attachments, multi mailbox forwarding, custom domain and subdomain supported

   Positive comment by donsalieri · Mar 4, 2022

   SimpleLogin can be used for the same purpose as Firefox Relay, plus it allows setting up aliases for custom domains. It is also open-sourced and there is support to self-host it on your own servers.
