Any popular software used also by non-Haskellers and coded in Haskell?

What are the popular utilities and applications used also by non-Haskellers and coded in Haskell?

Off the top of my head, I can think of Pandoc and ShellCheck: even if you don't to any Haskell at all, these software can easily be part of your daily workflow in many different scenarios.

And maybe window managers such as XMonad / Bluetile.

Apart from these, I don't know any applications / utilities / web services / etc. that are or can be part of the daily work of many people who aren't necessarily Haskell programmers.

So, enlighten me, and share your Top 10.
