O'Brien says, "We have users in 142 countries," and a passel of big-name companies are eschewing the use of Project in favor of OpenProj. Some of the companies he says have downloaded and installed OpenProj are Bank of America, Hewlett-Packard, General Electric, IBM, Siemens, Toshiba, Honeywell, Nortel, and Martin Marietta. Community members have also translated OpenProj from English to a dozen other languages.
"OpenProj replacement of commercial project management applications is highly disruptive for existing vendors and important to the entire industry," O'Brien says. OpenProj reads and opens Project files, a function that makes migrating from Project much easier, and OpenProj runs on Linux, Unix, Windows, and Mac OS.
According to its Web site, OpenProj's capabilities include Gantt and PERT charts, earned value costing, and other features common to project management applications.
OpenProj leapt to popularity on SourceForge.net shortly after its beta release in late 2007, with an average of 40,000 downloads per month. Its first full release came on January 10 of this year, and the next day it hit the 200,000 downloads milestone at SourceForge.net.
