SiteBar project is a solution for people who use multiple browsers or computers and want to have their bookmarks available from anywhere without need to synchronize them or take them along. The bookmarks are stored on a server - this could be:
SiteBar server run by its authors (you dont need to install SiteBar software - just sign up our service);
another public server running our SiteBar software;
your own server running our free SiteBar software.
The bookmarks are displayable/modifiable in almost any standards compliant browser.
SiteBar allows you keeping links private (the default) while giving you possibility to grant access to your bookmarks to selected user groups or to everyone. You can maintain your personal, family, team, company or enterprise-wide bookmarks with flexible access rules, permissions and customizable design!
Using RSS feeds you may monitor what additions have been added to certain SiteBar folders or to the whole SiteBar installation.
