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.
- Local SMTP server for intercepting and viewing emails
- User-friendly interface for email inspection
- Debug email source, both HTML, text & headers
- Bookmark emails for quick access
- Light & dark color schemes
- Print emails as PDF
At present, only a macOS build is available. Windows and Linux builds are pending due to lack of testing environments. Contributions from users with access to these platforms are more than welcome.

To distribute Phost on macOS, the application needs to be signed and notarized through the Apple Developer Program, which costs €100 annually. If you find Phost useful, please consider supporting its development and maintenance through GitHub Sponsors. Your support helps cover these costs and enables continued development of this open-source tool.
