Silent device identification with a persistent visitor ID and granular signals — a privacy-first complement to reCAPTCHA's challenge-and-score model, with no data sent to Google.
tracio.ai: Stable visitor identifier across sessions
reCAPTCHA: No persistent visitor identity
tracio.ai: 24 smart signals + confidence score
reCAPTCHA: A single risk score (0.0–1.0)
tracio.ai: MIT-licensed, public SDK
reCAPTCHA: Closed, Google-hosted script
We believe in transparency. Here is where we excel and where reCAPTCHA has genuine strengths.

Removing challenge friction often improves conversion, while tracio.ai adds granular bot classification and a persistent visitor identity reCAPTCHA does not provide.
Add the tracio.ai client SDK alongside your existing reCAPTCHA implementation. tracio.ai runs invisibly with no user-facing changes
Update your bot detection logic to use tracio.ai's detailed bot classification instead of reCAPTCHA's binary score. You can remove reCAPTCHA challenges entirely
Remove the reCAPTCHA script and site key. Your users will no longer see any challenges, puzzles, or friction — detection happens silently in the background
