## why Cap?
|
|
|
|
- ⚡️ **250x smaller than hCaptcha**
|
|
cap's widget library is extremely small, only 12kb minified and brotli'd.
|
|
- 🔒️ **Private**
|
|
cap's usage of proof-of-work eliminates the need for any tracking, fingerprinting or data collection.
|
|
- 🌈 **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 proof-of-work instead of complex puzzles, making it easier for humans and harder for bots
|
|
- 🧩 **Standalone mode**
|
|
cap offers a standalone mode with Docker, allowing you to use it with languages other than JS.
|
|
- 💨 **Invisible mode**
|
|
cap can run invisibly in the background using a simple JS API.
|
|
- ☁️ **Floating mode**
|
|
floating mode keeps your CAPTCHA hidden until it's needed
|
|
- 🌳 **Fully FOSS**
|
|
completely open source under the Apache license 2.0 license
