What is Cypht?

About Cypht

Cypht unifies your emails and RSS feeds in a simple, clear interface for easy message management.

A standard E-mail client

The driving force behind Cypht development is to provide combined views for multiple accounts, but it's also a standard E-mail client that lets you browse and manage IMAP folders and send outbound messages with SMTP.

Module system illustration

A set of plugins

Cypht is an application built entirely of plugins, or as we call them, module sets (which is obviously way cooler sounding than plugins), that are executed by the framework. Modules provide a flexible way to add new features or customize the program without hacking the code.

Privacy illustration

Privacy‑first

Cypht is Open Source (LGPL V2), and written in PHP and JavaScript. If you are looking for a lightweight webmail solution for an ISP, school, business, or just personal use, I hope that Cypht can help!
