Can I run my own Foxmarks server?
You can run parts of it yourself. Foxmarks was once based on the Open Source Application Foundation’s Cosmo Server, which you can download and install yourself. For a variety of reasons, mostly related to the volume of traffic we handle, we’re no longer using Cosmo, but Foxmarks remains compatible with it. Foxmarks should also run relatively well with any WebDAV server and less well with any FTP server; see the question above.
