Addy.io
Open-source email alias service that forwards anonymous addresses to your inbox.
Replacements
Listings that take over the same core job as Addy.io.
SimpleLogin
Open-source email alias service that protects your real inbox from spam.
SimpleLogin is also an open-source alias service, backed by Proton and tied into its ecosystem, with the best features and higher alias limits on a paid plan.
Firefox Relay
Email masking service from Mozilla that forwards aliases to your real inbox.
Firefox Relay is a closed-source masking service from Mozilla with browser extension mask creation, and it offers fewer free masks than Addy.io's unlimited aliases.
DuckDuckGo Email Protection
A free email forwarding service that gives you a @duck.com address and removes trackers.
DuckDuckGo Email Protection is free and strips trackers from forwarded mail, but it is closed source and cannot be self-hosted, so you rely on DuckDuckGo.
33Mail
Disposable email forwarder offering unlimited free aliases.
33Mail also gives unlimited free aliases, but it is closed source, cannot be self-hosted, and free aliases live on its shared subdomain with a dated interface.
Forward Email

Forward Email is another open-source forwarder, aimed at custom domains with unlimited aliases and free storage, requiring a domain and DNS configuration for full benefit.
Apple Hide My Email
iCloud+ feature that generates disposable email aliases for sign-ups.
Apple Hide My Email is built into iOS Settings but closed source, needs a paid iCloud+ subscription and works only within the Apple ecosystem.
Erine.email
Free open-source anti-spam service for your existing email address.
Erine.email is free and open source and works with an existing inbox, but it is a smaller project with limited information on feature depth.
Cloaked
A privacy service that creates masked identities and scans for data brokers selling your personal information.
Cloaked adds masked phone numbers and a data broker scan to email masking, but it is closed source, hosted only and US-focused.
Also worth comparing
These listings name Addy.io as their own alternative, so the relationship runs both ways.
10 Minute Mail
Free temporary email address that stops receiving mail after ten minutes.
Addy.io offers unlimited free forwarding aliases and is open source with a self-hosting option, so addresses stay recoverable, unlike expiring ten-minute inboxes.
Guerrilla Mail
Web service that gives you a disposable email address instantly, with no signup.
Addy.io offers unlimited free forwarding aliases, is open source and can be self-hosted, keeping mail private instead of in an unencrypted public inbox.
