NetPositive, sometimes called Net , the browser included with BeOS. The program has rather spartan presentation skills, so while it supports HTML 4.0 and parts of JavaScript, but neither Java nor stylesheets or frames.

The latest official version before buying the Be Incorporated by Palm was 2.2.1, but there is also a 3.0d3 called beta version and a leaked version 2.2.2, in which the RSA encryption engine was replaced by OpenSSL. Possibly Be wanted to free the source code of commercial ingredients to enable a proposed publication as open source, such as the Open Tracker project that the source code of the BeOS file manager Tracker released under a minimally modified BSD license.

The compiled version of NetPositive with all encryption libraries and tools are not included in the operating system, such as HTTP or FTP program modules has uncompressed size from 1.4 to 1.7 MB, depending on the selected ( or available ) encryption strength.

NetPositive can be embedded using the operating system to the mechanisms provided for in other applications, the user or the operating system itself. When Microsoft released the Active Desktop in Windows, has been touted as the great progress. Be has then later has claimed to have replicated this functionality in Internet Explorer in Windows with NetPositive in " nine lines of code ".

NetPositive remained the default browser of the operating system ZETA, eg for opening files, in spite of the still incomplete realization of the operating system interface of Mozilla Firefox for the BeOS. But then, finally, the use of Firefox was announced instead of NetPositive for Zeta.


Originally NetPositive the only browser for BeOS. However, after BeOS gained popularity, the company Opera Software ported their browser Opera also on BeOS. Similarly, open- source browser like Mozilla ( BeZilla ) and Lynx were ported to BeOS. And with Net (using the Gecko engine ) and Themis were even written two NetPositive clones.

Error Messages

NetPositive gave error messages in the form of a haiku, a Japanese form of poetry. From this it also unlocks the current name of the open -source successor of BeOS, Haiku.
