addy.io vs Skudo: which free plan gives you more?

Francesco Sappa

Share

Both services give you free email aliases, but they are not equal. Skudo Free gives you more mail, more features and more encryption, and you do not need a paid plan to get them. Every addy.io figure below comes from its own pages, checked on 20 September 2026.

In short

  • On shared domains (like skudo.me), Skudo lets you create 30 new aliases a month. addy.io allows 10 active on Free and 50 on Lite, at $1 a month.[1]
  • Skudo Free includes replies, tracker removal, your own domain and 1 GB of mail a month.[6] On addy.io they need a paid plan.[1][2]
  • Your notes are encrypted in your browser, and sign-in never sends your password.[6] addy.io leads on two points: unlimited aliases on your own subdomain, and public server code.[1][5]

What "shared domain" means

A shared domain is an ending many people use, like skudo.me. Your own subdomain, like yourname.skudo.org, belongs to you alone. Skudo counts how many aliases you create each month. addy.io counts how many are active at once.[4]

The difference adds up. Use the full allowance and keep your aliases, and Skudo passes addy.io Lite's 50 in month two.

Aliases on one shared domain over six months. Skudo Free reaches 30, 60, 90, 120, 150 and 180. addy.io stays at 10 active on Free and 50 on Lite.

Where addy.io is ahead

Two things

  • Unlimited aliases on your own subdomain. Skudo allows 75 new a month there.
  • Public server code. addy.io publishes it under AGPL-3.0.[5] Skudo's browser extension is source-available, and the server code is not public yet.

Which to pick

Pick Skudo if you want Pick addy.io if you want
Replies and tracker removal without paying To read the server code that handles your mail
Your own domain on a free plan Unlimited aliases on one subdomain
A lot of mail: 1 GB a month To pay for a plan that scales

What Skudo stores, and what a court order could reach, is in what Skudo can hand over when a court orders it.
