A browser-based email aggregator that combines all your accounts into one unified inbox.

Core Features

  • Unified inbox for multiple email accounts (IMAP/SMTP, JMAP, EWS)
  • Plugin-based module architecture for easy customization
  • Built-in RSS/news reader combined with email
  • Self-hosted for full data privacy and control
  • Lightweight web app, works in any browser with no installation

What It Can't Do

  • •Requires self-hosting with PHP and MySQL/SQLite – not for non-technical users; 2. Some email providers need 'less secure apps' access or app-specific passwords; 3. No built-in end-to-end encryption (PGP) for emails.

Use Cases

  • Managing multiple personal or work email accounts from one interface
  • Organizations wanting a self-hosted email aggregation tool without third-party cloud services
  • Lightweight alternative to desktop clients like Thunderbird or Mailspring

Cypht is an open-source, self-hosted webmail client that aggregates multiple email accounts into a single unified inbox. It supports IMAP/SMTP, JMAP, and Exchange Web Services (EWS), making it compatible with Gmail, Outlook, and any standard email provider. Unlike traditional desktop clients, Cypht runs entirely in your browser and is built on a modular plugin architecture (called module sets), allowing you to add or customize features without hacking core code. It also doubles as an RSS/news reader. Key features include combined folder views, search across all accounts, and a focus on privacy (you control the server). Ideal for users who manage many inboxes and want a lightweight, customizable, and private alternative to services like Gmail or Thunderbird.
