Please note, as of March 1, 2021, Hosted Parsoid is sunsetting. Currently, we are closed for new signups. We are still offering our world class wiki hosting plans. For more information about why Hosted Parsoid is saying goodbye, please see our announcement on Medium.
Hosted Parsoid is a service offered by MyWikis to other wikis not on MyWikis that aren't able to install the Parsoid service on their servers because of shared hosting limitations. Parsoid is used to run VisualEditor, a game-changing WYSIWYG (what you see is what you get) editor that allows a user to edit a wiki page just as they see it normally, instead of going through wikitext.
Wikis on MyWikis do not need Hosted Parsoid. VisualEditor is included with MyWikis Pro and plans above it.
