Hello,
I have just set up a very basic web service for Parsoid at
It gives you the ability to browse the English Wikipedia as Parsoid currently sees it, and provides forms for wikitext -> HTML DOM and HTML DOM -> wikitext conversion tests.
Round-tripping is brand new and very limited, and does not support the preservation of variable whitespace, templates and other complex constructs yet. Currently 154 parser tests are passing in the new --roundtrip mode that Subbu added last week.
