As a point of comparison, Rackspace and Nebula have contributed the most lines of code to OpenStack overall -- unsurprising, given that they launched the OpenStack initiative back in 2010. Rackspace has contributed 2,598,806 lines of code in all (33 percent of the total); Nebula is credited with 1,819,596 (23 percent). Red Hat comes in at a distant third overall with 592,373 lines (8 percent). The fourth-largest contribution, 542,645 lines, came from a collective of 300 independent engineers. DreamHost, IBM, and HP follow with 274,686, 244,323, and 224,955 respectively. (Dreamhost claims 14th place overall with 57,750 contributed lines of code.)
In terms of overall commits since the birth of OpenStack, Rackspace leads with 7,021, which is 21 percent of the total. Next comes Nebula with 5,436, followed by Red Hat at 5,368, independent developers with a collective 2,626, HP with 1,446, and IBM with 1,318. (DreamHost is down in the No. 17 spot with 333 commits.)
These figures are the tip of the iceberg: With Stackalytics, you can dig in to which modules have received the most contributions (nova, both in terms of lines and commits), which developers have submitted the most lines (Sirish Chandra Bitra with 118,814) and commits (Tomas Sedovic, 133), and more.
