The Open Source Hirsch Index, introduced by Prog.AI, is a graph algorithm similar to the academic h-index. The index is equal to N if a developer has at least N projects, each with at least N commits from the developer, and each project has at least N stars.
≥ 27
is like winning a Nobel Prize—only a few hundred people reach this level.
≥ 13
puts you in the top 10,000, which is on par with earning an Olympic medal.
≥ 8
places you in the top 100,000, where you’ll find people making a serious impact in tech—think billionaires and CTOs of unicorn companies.
≥ 3
lands you in the top 1 million, the marathoners of the industry.
