Ocaml for web development
We (a small company creating specialized inventory management and e-commerce systems) use Dream for web development. Webmachine and Cohttp for creating RESTful APIs. HTTP-clients with Ocurl and Cohttp. We are very happy with our choice of technologies.

Easy parsing with reasonable error messages in OCaml's Angstrom
PARSER combinators are widely used in the world of functional programming, and OCaml's Angstrom library is one of them. It is used to implement many foundational parsers in the OCaml ecosystem, eg HTTP parsers for the httpaf stack.
