Flagsmith edges out Growthbook modestly on homepage messaging, 81 to 77. Here's where the gap comes from.

Flagsmith is clearer about what it does (100 vs 62 on clarity). Flagsmith's hero ("Ship Faster and Control Releases with Feature Flag Manageme…") names something concrete, while Growthbook's ("The #1 Open-Source Feature Flag & Experimentation Platform") stays abstract. Growthbook is better at saying who it's for (ICP: 48 vs 35).

Flagsmith uses a "Trust / Authority" positioning while Growthbook goes with "Platform / Ecosystem" — fundamentally different approaches to winning the same buyer.
