Github and Harness are nearly tied on overall homepage messaging — 83 vs 81. The difference comes down to where each invests its messaging effort.

Github is clearer about what it does (100 vs 62 on clarity). Github's hero ("Search code, repositories, users, issues, pull requests...") names something concrete, while Harness's ("AI for Everything After Code") stays abstract. Harness is better at saying who it's for (ICP: 86 vs 53). Harness's targeting is crystal-clear, while Github's is decent.

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