Protect any API from
bots & abuse. Zero code.

Yes. Kapsule was designed for builders without a security background. If you created your app with an AI tool or a no-code platform, you configure everything from a visual dashboard — no security knowledge required. The only change to your app is swapping your API URL for your new Kapsule URL, a one-line change you (or your AI coding assistant) can make in seconds.

A Backend-For-Frontend is a protective layer that sits between your app and your APIs — think of it as a security checkpoint. Instead of the browser calling your API directly, it calls the BFF, which validates, secures, and forwards each request. Kapsule gives you a fully managed BFF without writing or deploying any backend code.

No. Kapsule works as a secure proxy in front of your existing API — whether it's a legacy system, a serverless function, or something an AI tool generated for you. You point Kapsule at your endpoint, configure your security rules in the dashboard, and swap the URL in your app. Your backend stays untouched.

Kapsule integrates natively with Cloudflare Turnstile, an invisible CAPTCHA alternative. Your frontend obtains a Turnstile token, and Kapsule verifies it server-side before any request is forwarded to your API. Requests without a valid token are blocked at the gateway.

Origin validation ensures API requests are only fulfilled when they come from your approved frontend domains. This prevents other websites, scripts, or tools from consuming your API endpoints directly, protecting your data and your infrastructure costs.

Most people secure their first endpoint in under five minutes. Create a free account, register your API URL, enable the protections you need — bot protection, origin validation, rate limiting — and replace the API URL in your app with your new Kapsule endpoint.
