Cypht

Cypht is an open-source webmail client designed to provide a fast, minimal interface for reading email from one or more IMAP accounts. It focuses on being lightweight and modular, with optional components that can extend functionality while keeping the core UI simple.

Key Features

• IMAP webmail interface with mailbox/message browsing and message viewing
• Multi-account support (aggregate multiple IMAP accounts into one web UI)
• Modular architecture (features provided via modules/plugins rather than a monolith)
• Optional SMTP support for sending mail (depends on deployment configuration)
• Optional Sieve support for server-side mail filtering (where supported by your mail server)
• Theming/customization via templates/assets (project includes UI assets and templates)

Use Cases

• Provide webmail access for users with existing IMAP mailboxes
• Consolidate multiple IMAP accounts into a single web interface
• Deploy a minimal webmail UI for constrained servers or internal-only access

Limitations and Considerations

• Feature set and polish can be more minimal than “groupware-style” webmail suites (e.g., advanced calendar/contacts are not a primary focus)
• Some capabilities (sending mail, Sieve filtering) depend on server support and configuration rather than being purely client-side

Cypht fits deployments that want a straightforward, extensible webmail client with multi-IMAP aggregation and a lightweight footprint. Its modular design makes it suitable when you want to enable only the features you need and keep the interface simple.
