About

Phost is a email debugging tool and local SMTP server, developed primarily in PHP. Instead of sending your development emails to Mailtrap or MailHog, you can use Phost to debug your emails inside a beautiful self-contained desktop app.

We leverage a powerful stack of modern technologies:

• Laravel/Livewire -> For dynamic, reactive interface
• NativePHP -> Electron wrapper for PHP built apps
• ReactPHP -> Powering the SMTP server component

While Phost may not yet match the feature set (or stability) of some paid alternatives, it serves as an exploration of the capabilities of a native PHP stack.
