What is it?

Cypht combines all of your email accounts into a single interface without replacing them. It works as a standard email client for browsing folders, reading, and sending messages, and it also functions as a news reader for RSS and Atom feeds.

It supports IMAP and SMTP, JMAP, and Microsoft Exchange through Exchange Web Services (EWS). Every feature is implemented as a module set, so features can be added or customized without modifying the core code.

Cypht is distributed as source code, a Docker image, and a Composer package, so it can be run on your own server.
