JellyVNC is a simple bookmark manager for the built-in Screen Sharing application in Mac OS X. It allows you to create local or remote bookmark entries including a title, hostname or ip address, username and even a custom port. You can browse your local network using Bonjour to discover which computers have VNC running and connect to them - or add them to a bookmark.
JellyVNC features a menulet in the top menubar giving you one-click access to all your bookmarks.
Choosing the bookmark and clicking Connect will bring up the built-in Screen Sharing application and prompt you for a password which can be saved in the keychain for faster access next time.
JellyVNC lets you bookmark and use any device which has the VNC protocol running - it isn't limited to Macs.
This application is very useful if you need to connect and manage several computers using VNC - whether it is your family or business.
