Cypht

Cypht is an open-source webmail client and RSS aggregator designed around a modular plugin architecture. It unifies multiple IMAP accounts into a single inbox and supports composing messages with Markdown, while offering a flexible plugin system to extend functionality.

Key Features

• Unified inbox views for multiple IMAP accounts and RSS feeds, with standard mailbox navigation
• Modular plugin sets (module sets) that can be added or replaced to customize the application
• Server-side Sieve email filtering to automatically organize the inbox
• Global search across all connected accounts and feeds from a single form
• Markdown-enabled email composition with conversion to HTML on send
• Flexible authentication methods and auto-discovery based on user domain
• Sessions and data storage in PDO-compatible databases or flat files
• Docker installation option via an official image for easier deployment
• Extensible with modules for IMAP, SMTP, LDAP, WordPress, GitHub, and more
• Built with PHP and JavaScript, emphasizing a lightweight, plugin-driven architecture

Use Cases

• Individuals managing multiple email accounts and RSS feeds from one interface
• Small businesses or schools needing a self-hosted, customizable email solution
• Organizations extending capabilities through modules (e.g., WordPress, GitHub, LDAP) to fit site-specific needs

Limitations and Considerations

• PHP version and extension requirements vary by version; ensure compatibility with PHP 8.1+ for newer releases
• Some features rely on server capabilities (e.g., IMAP/SMTP extensions and Sieve support on the mail server)
• The modular approach adds flexibility but may require more setup and maintenance than monolithic clients

Conclusion

Cypht provides a modular, self-hosted approach to email and RSS aggregation, enabling unified access across accounts and extensible functionality through plugin sets. Its PHP/JavaScript foundation and Docker deployment model make it adaptable for personal use or small organizations that want configurable, private-mail tooling.
