Fly edges out Vercel modestly on homepage messaging, 83 to 78. Here's where the gap comes from.

Vercel is clearer about what it does (90 vs 75 on clarity). Fly has stronger CTAs (80 vs 60). Vercel triggers decision paralysis with 8 competing CTAs, while Fly keeps it focused at 2.

Both sites use the "Platform / Ecosystem" positioning archetype — they're competing on the same narrative, which means differentiation has to come from execution, not framing.
