This page contains a list of WebDAV services which provide a free plan and which users have reported success using with Zotero. Free plans may have some limitations. All service providers also offer larger and less limited paid plans. The list is not exhaustive. Service providers not listed here may still work with Zotero.
This list is user-generated and does not entail an endorsement of any service by Zotero. Zotero works with correctly-specified WebDAV servers and can provide only minimal support for problems with 3rd party WebDAV providers.
