# Deploy Cap Captcha with Easypanel

URL: /templates/cap-captcha

Cap is a lightweight, open-source CAPTCHA alternative to reCAPTCHA, hCaptcha and Cloudflare Turnstile. It uses proof-of-work and instrumentation challenges instead of visual puzzles, so users are verified in the background without picking out crosswalks or storefronts. The widget is about 250x smaller than hCaptcha, sends zero telemetry, and this standalone server includes an admin dashboard for managing site keys and viewing challenge analytics.

## Installation notes

Open the dashboard at your assigned domain and log in with the admin key you set below (auto-generated if left blank — find it in the service environment variables after deployment). Create a site key from the dashboard, then drop Cap's widget script into your site and point it at this server's domain, per the integration guide at trycap.dev/guide.
