Do you know which one? They are not all created equal, and many that I have used will only handle Discourse in read-only mode. edbrowse which I have used in the past for twitter has the best JS implementation of any text-based browser I know (it also has the worst interface for sighted people).
I just tried, and I cannot create an account on try.discourse.org or log into meta with edbrowse.
$ edbrowse https://meta.discourse.org/

(People who have used ed on Unix will recognize the interface. For everyone else it’s opaque at best.)
I gather that many people use screen readers these days, which presents a much different interface, and one Discourse will probably work better with.
