ocamlbrowser is actually the name of a program that has been distributed with the OCaml compiler for a very long time. It was written with LablTk, supported by Jacques Garrigue, and was inside the "ocaml distribution" (instead of an external tool) because it accessed .cmi files .cmi ways based on the internal details of the compiler.
So the short answer is “yes, just call ocamlbrowser to your terminal” (assuming your distribution is hosted on ocamlbrowser with the compiler, which may or may not be, there may be a separate ocamlbrowser package instead). The appearance of the tool may be a bit outdated compared to the brilliant version of Eclipse, but it really exists and works great.
