VMS Mosaic, a version specifically targeting OpenVMS operating system, was one of the longest-living efforts to maintain Mosaic. Using the VMS support already built-in in original version (Bjorn S. Nilsson ported Mosaic 1.2 to VMS in the summer of 1993), developers incorporated substantial part of HTML engine from mMosaic, another defunct flavor of the browser. As of 3 September 2003 (2003 -09-03), VMS Mosaic supports HTML 4.0, OpenSSL, cookies, and various image formats including GIF, JPEG, PNG, BMP, TGA, TIFF and JPEG 2000 image formats. The browser works on VAX, Alpha, and Itanium platforms.
Another long-lived version of Mosaic – Mosaic-CK, developed by Cameron Kaiser, – saw its last release (version 2.7ck9) on July 11, 2010. The stated goal of the project is "Lynx with graphics" and runs on Mac OS X, Power MachTen, Linux and other compatible Unix-like OSs.
