hCaptcha alternative — SignupDoggy comparison (2026)

hCaptcha alternative for indie SaaS teams. Pricing, accuracy, integration time, and which one fits a 2-50 person team. Honest comparison of hCaptcha and SignupDoggy.

hCaptcha alternative

hCaptcha is the privacy-focused alternative to Google reCAPTCHA. It challenges users with image-recognition puzzles, pays publishers for the training data, and doesn't ship user behavior to Google.

LIKE TURNSTILE, hCaptcha is a CAPTCHA — not a fraud API. It challenges the browser session and nothing else. Headless scripts and mobile bots pass through unchanged.

Use hCaptcha as the FIRST stage of a 2-stage funnel, with SignupDoggy as the server-side second stage. The full 2-stage pattern is at /blog/cloudflare-turnstile-vs-server-side-fraud-api.
