Why reForge Captcha

Everything bots hate, users love

Built for developers who want real protection without making their users suffer.

Risk Engine

Every request is scored in real-time. Browser fingerprint, behavior patterns, IP reputation, and more — all combined into a single score.

Drop-in Integration

One script tag and two lines of HTML. Compatible with any framework — React, Vue, plain HTML, PHP, Laravel, WordPress, and more.

Server-Side Verify

Never trust the client. Verify every token server-side with a simple REST API call before processing your form.

Real-Time Analytics

Per-site dashboards showing pass rates, bot traffic, score distributions, and geographic threat data — updated live.

Privacy First

No cookies placed on visitor browsers. No data sold. GDPR and CCPA compliant. We score signals, not people.

Truly Free

Unlimited sites, unlimited verifications, unlimited API keys. No credit card required. No rate limits on the free plan.

Quick Integration

Up and running in 2 minutes

No complex SDK setup. Just a script tag and an API call.
