Hey folks 👋
I’ve been working on a tool called <a href="https://mailfrom.dev" target="_blank" rel="noopener nofollow">Mailfrom.dev</a> – a sandbox SMTP server designed for staging and development environments. If you’ve ever had to deal with testing email flows like password resets or onboarding confirmations, you know how messy it can get when you don’t want to send real emails.
<a href="http://Mailfrom.dev" target="_blank" rel="noopener nofollow">Mailfrom.dev</a> lets you send emails to a fake SMTP server, where you can inspect everything in a web UI — no emails actually go out to the end users and you can also share everything with you team.
I was frustrated with how expensive or overly complex other tools in this space are… I wanted something affordable and dead simple to use. Just check the pricing — you’ll see what I mean.
It’s fully open to the public now, and I’d love any feedback, thoughts, or feature suggestions.
Tech stack:
<ul>
<li>Backend: Laravel (Horizon, Reverb, Cashier)</li>
<li>Frontend: Vue 3 + shadcn + reka</li>
<li>Infra: k3s on Hetzner, S3 &amp; SES on AWS</li>
</ul>
It’s live now and I’d love your feedback, feature ideas, or general thoughts. If you’ve had similar needs or hacked together a solution before, I’d love to hear how you handled it.
Also, I just launched it on Product Hunt — if you want to check it out or support the launch:

MailFrom.dev - I built a sandbox SMTP server for email testing in staging/dev – feedback welcome!

<a href="https://github.com/maildev/maildev" target="_blank" rel="noopener nofollow">https://github.com/maildev/maildev</a> used this for years. Free and OSS.

Looks like a nice little service for trapping mail. I could see using this in a team or even sharing with clients. For quick email testing I think I’ll stick to a simple mailpit docker container.

What are the benefits compared to smtp4dev? 🤔

So it seems your create again Maildev open source existing tool? :D
