Integrations

Works with every platform

One script tag for detection. Server-side SDKs for blocking. 8 languages, every major framework.

One Script Tag

Detection works with just one line of HTML. No backend required.

8 Server SDKs

Node.js, Next.js, Express, Python, PHP, Ruby, Go, WordPress.

Middleware Pattern

All SDKs follow the same middleware pattern, consistent across languages.

Fail-Open Design

If our API is down, your site keeps working. Never a single point of failure.

< 50ms Latency

Cached lookups ensure verify calls don't slow down your site.

Action-Based Response

Response includes action: allow, block, challenge, throttle, or log.

Response Headers

X-CrawlGuard-Score and X-CrawlGuard-Classification on every response.

Challenge Integration

SDKs handle challenge redirects automatically.

HTML / Script Tag

One line of code. Works everywhere.

<script src="..." defer>
