 FreeBSD has a repository of over 24 @,@ 000 applications that are developed by third parties . Examples include : windowing systems , web browsers , email clients , office suites and so forth . In general , the project itself does not develop this software , only the framework to allow these programs to be installed , which is known as the Ports collection . Applications may either be compiled from source ( " ports " ) , provided their licensing terms allow this , or downloaded as pre @-@ compiled binaries ( " packages " ) . The Ports collection supports the current and stable branches of FreeBSD . Older releases are not supported and may or may not work correctly with an up @-@ to @-@ date Ports collection .
