+## Features
+- ⚡️ **250x smaller than hCaptcha**:
+  Cap is lightning fast, so your pages load instantly and users don't wait around
+- 🔒️ **Private & GDPR compliant**:
+  No more tracking or data collection. Cap is GDPR compliant and keeps your users' data private
+- 🌈 **Fully customizable**:
+  Cap is self-hostable so you can customize both the backend & frontend — or you can just use CSS variables
+- 🤖 **PoW-based**:
+  Cap uses PoW instead of frustrating image puzzles, making it easier for humans and harder for bots
