Many [[NAS|https://en.wikipedia.org/wiki/NAS]] or [[Subversion|https://en.wikipedia.org/wiki/Apache_Subversion]] servers support WebDAV out of the box. Setting up your own server might take some effort though:
[[dav-server|https://github.com/edrex/dav-server]] is a quick way to serve up a folder of HTML ~TiddlyWikis.
[[webdav server|https://play.google.com/store/apps/details?id=com.theolivetree.webdavserver&hl=en]] for Android lets you put wikis in your pocket. You can share with other devices on the local network too.
!! Existing Wikis
~WebDAV support was added Feb 16 2016. If you created your wiki before that, you'll need to [[Upgrade|Upgrading]] to enable ~WebDAV.
None of the ~WebDAV hosting services tested (~~box.com~~, ~~swissdisk.com~~) support accessing HTML files via a webbrowser, so they won't work with ~TiddlyWiki. Maybe someday soon there will be a free ~WebDAV hosting service for ~TiddlyWikis.
