Protect Your Node.js Apps Against Threats
Bot protection for Node.js. Trusted by developers worldwide.
Node.js enables your application with non-blocking I/O and JavaScript everywhere. Automated form submissions, API abuse, and account takeover attempts target your endpoints. Implementing custom rate limiting middleware, maintaining IP filtering logic, and handling bot detection manually diverts focus from core application logic.
Friendly Captcha works natively with your Node.js stack. Install the SDK via npm, initialize the verification client with your credentials, and validate CAPTCHA responses in your route handlers or middleware. The SDK handles asynchronous verification with Promise-based APIs that fit naturally into async/await workflows. Bot protection that integrates cleanly with any Node.js framework-no architectural overhead, no blocking operations.
