Github edges out 6dngine significantly on homepage messaging, 83 to 37. Here's where the gap comes from.

Github is clearer about what it does (100 vs 72 on clarity). Github's hero ("Search code, repositories, users, issues, pull requests...") names something concrete, while 6dngine's ("wiki") stays abstract. Github is better at saying who it's for (ICP: 53 vs 43). Github has a much stronger pricing page (90 vs 0). 6dngine doesn't have a detectable pricing page at all.

6dngine uses a "Platform / Ecosystem" positioning while Github goes with "Community / Movement" — fundamentally different approaches to winning the same buyer.
