# Alpine vs Gnus

- Alpine: Menu-driven terminal email client descended from Pine, with built-in help, setup screens and native Windows builds.
- Gnus: Mail and news reader built into GNU Emacs, with back ends for IMAP, POP3, local mail folders and NNTP.

## Differences

- Alpine is a full-screen terminal client; Gnus is a mail client that runs inside Emacs.
- Only Gnus has built-in Maildir.
- Alpine is written in C; Gnus in Emacs Lisp.
- Configuration: Alpine uses built-in setup screens, stored in .pinerc, and Gnus uses Emacs Lisp in init.el or ~/.gnus.el.
