Cypht

Cypht, pronounced "sift," is an innovative open-source webmail client designed to centralize all your email accounts and RSS feeds into a single, coherent interface. Unlike traditional email clients that manage individual accounts, Cypht acts more like a news reader, aggregating content from various sources into combined views such as inbox, unread, sent, and flagged messages. This eliminates the need to switch between different platforms to check emails or news updates, streamlining your digital communication.

The core strength of Cypht lies in its entirely modular architecture, where all functionalities are implemented as 'module sets.' This design allows for unparalleled flexibility, enabling users to add new features, customize existing ones, or even replace components without altering the core code. Beyond its aggregation capabilities, Cypht functions as a full-fledged email client, supporting IMAP folder navigation, SMTP for sending messages, and advanced features like server-side Sieve filtering. It's written in PHP and JavaScript, making it a lightweight and adaptable solution for personal use, businesses, ISPs, or educational institutions seeking a self-hosted, customizable webmail platform.
