| Built-in mailbox | ✅ Yes (read, reply, compose) | ❌ No (forwarding only) |
| Open source | ✅ Yes | ✅ Yes (MIT) |
| Free plan | 1 domain, 10 aliases, 100 emails/mo | Unlimited aliases (shared domain), 10 MB/mo |
| Paid entry price | €9/mo (Pro) | $1/mo (Lite), $3/mo (Pro) |

AnonAddy is especially generous on its free plan: unlimited aliases on its shared domain (@anonaddy.com or @addy.io), ideal for personal use without your own domain. The main limit is bandwidth (10 MB/month of received email).
SMTPy bets on your own domain from the start: 1 custom domain, 10 aliases, 100 emails/month. If you already have a domain and want a professional email identity, SMTPy clearly wins.
AnonAddy is built for pure forwarding: emails are relayed to your primary inbox, with no storage or reading interface. You manage aliases from a dashboard, but you do not read your email inside addy.io.
SMTPy includes a full web mailbox (shared inbox): you can read, search, reply, forward, and archive email directly in the interface — a significant advantage for centralizing your communications.
Both services are open source. AnonAddy can be self-hosted (a Laravel install), but the process is complex. SMTPy is designed for self-hosting from the ground up with Docker, complete documentation, and a one-command install.
AnonAddy is cheaper ($1/month for custom domains). SMTPy costs more but offers more: a built-in mailbox, advanced analytics, webhooks, multi-user teams, and a full API.
