Didit vs Zyphe Age Verification

Didit has no write-up on Specifiction yet; its figures are above.

Zyphe Age Verification checks whether a user meets the minimum age configured for access to restricted products, services, or content. Rules can be set per verification flow and adjusted for a market, such as an 18- or 21-year threshold. The service checks government identity documents covering more than 4,000 document versions from 213 countries and territories. Checks include active liveness, anti-spoof measures, and injection-attack detection. After an initial verification, a user can present a KYC Passport zero-knowledge proof of being over the threshold without revealing a birth date or document. A location step compares GPS with the IP country and flags VPN or proxy use and blacklisted IPs. Zyphe says documents are processed transiently and stored encrypted in the user's vault; it retains the result, audit log, and cryptographic proof. Integration options include APIs, browser and Node.js SDKs, hosted verification links, iframe embedding, and mobile WebView. Business is listed at free, with a monthly KYC allowance; checks above the allowance and add-ons are charged per check. Zyphe says it does not offer facial age estimation.
