Compare ยท Terminal and editor clients

aerc and Pagkugi

Asynchronous terminal mail client for technical users.

At a glance

Several account types, first-class Git-by-email workflows, Vim-style control, and GnuPG integration.

Where Pagkugi differs. The closest technical relative in spirit, but terminal-based and protocol-heavy, where Pagkugi is graphical, focused, and deliberately HTML-averse.
