    aerc (pronounced /ɑːrk/)[3] is a text-based free and open-source email client for Unix-like Operating systems. aerc is written in Go, and is similar to alpine, cone, Gnus, meli (email client),[4] and mutt, in that the user interface occupies a full terminal screen (TUI), which arguably is par to GUI clients.[5]

    aerc is packaged for various operating systems,[6] e. g. FreeBSD,[7] or Arch Linux via AUR,[8] and Debian anticipated.[9]

    About 100 people have contributed to aerc so far.[1] TecMint recommended it as "one of the best email clients that run in the terminal."[10]

    At FOSDEM 2020, a meeting of the "closely linked Sourcehut and aerc communities" was organized.[11]
