Clojure has a pattern matching library https://github.com/clojure/core.match https://github.com/clojure/core.match. And I think clojure is the most widely used

  There is one for Common Lisp too https://github.com/m2ym/optima https://github.com/m2ym/optima

  Not by a long shot, Emacs Lisp is the most widely used Lisp dialect, by far. Clojure isn't even close.

    Maybe if used means, "to create web applications".

  Yes, I've used it, and it's quite nice. But it's not quite the same. In Elixir (and of course Erlang), pattern matching is pervasive. You use it when defining functions by defining multiple heads, each with a different patter. You can also use it when binding variables. For example: {:ok, result} = compute_data(some_value, another_value) If compute_data doesn't return a pair where the first value is :ok, it will throw an error.
