cypht

Cypht is a lightweight, open source webmail aggregator that combines all your email accounts into one unified interface. Built with PHP and JavaScript, it supports multiple email protocols (IMAP/SMTP, JMAP, and EWS) and works like a news reader for email—without replacing your existing accounts. Cypht also functions as a standard email client for browsing IMAP folders, managing messages, and sending outbound mail via SMTP.

Key Features

• Multi-Account Aggregation: View and manage emails from multiple accounts in a single combined interface
• Protocol Support: Compatible with IMAP/SMTP, JMAP, and Exchange Web Services (EWS)
• Modular Architecture: Built entirely on plugins (module sets) for flexible customization and extensibility
• Email Management: Browse IMAP folders, read messages, and send outbound mail with full client functionality

Use Cases

• Email Power Users: Consolidate multiple email accounts from different providers into one unified inbox
• Enterprise Users: Integrate Exchange, Gmail, Outlook, and other email services in a single application
• Privacy-Conscious Users: Self-host your webmail aggregator on your own infrastructure with full control

Who Is It For

Cypht is ideal for users who manage multiple email accounts and want a lightweight, customizable alternative to juggling separate clients or web interfaces. It appeals to privacy-focused individuals, system administrators, and developers who prefer open source solutions they can self-host and extend with custom modules.
