Which BeOS web browser was bundled with BeOS from version 4?

The BeOS web browser bundled with BeOS from version 4 was NetPositive.

NetPositive was Be’s lightweight native browser, designed specifically for the BeOS environment. It matched the operating system’s emphasis on responsiveness and multimedia performance, and it was distributed alongside built-in tools such as BeMail.

NetPositive supported core web technologies of its era, including HTML and some JavaScript, but it was not a modern full-featured browser. It is sometimes confused with WebPositive, the later browser created for Haiku, the open-source successor to BeOS. Cyberdog and OmniWeb were associated with other platforms, not BeOS’s standard browser.
