Portreeve: features, pricing and alternatives

About Portreeve

Portreeve targets abuse that comes from one person using many accounts, such as repeat free trials, AI credit farming, self-referrals and coupon stacking. A single API call links accounts by signals such as device, card fingerprint and email and returns a decision of allow, review or block together with the reason, before a credit, bonus or discount is issued.

A dashboard shows a live event stream with each decision and its reason, a review queue, clusters of linked accounts and analytics, with a versioned policy. The site contrasts it with CAPTCHA and disposable email lists, one-trial-per-email rules, per-account coupon limits and card scoring tools, which judge accounts rather than the people behind them. It covers event types such as signups, trial starts, checkout attempts, referral claims and coupon redemptions.

The free tier includes 1,000 screenings a month with no card needed, and integration is one API call. Paid plans are listed on the pricing page. Integration is described as a single API call, with documentation and a scanner and checker tool available on the site.
