What Scamalytics does
Scamalytics looks at an IP address and returns a risk score from 0 to 100. According to the listing, the score also factors in the surrounding subnet, hosting block and ASN, so it can flag risky addresses before they are widely reported. You call it with a single HTTP GET request from a signup, login or checkout flow and act on the result.
The company was founded on 20 June 2012 in London, has 1 to 10 staff and is listed as Series A funded. That makes it much older than most AppSumo launches, which matters for a security tool.
Main features
- Fraud score, risk level and ISP risk score for each IP.
- Flags for public proxies, VPNs, Tor exit nodes, data centers (including AWS and Google Cloud) and Apple iCloud Private Relay.
- Search engine and crawler detection, so you do not block Googlebot by mistake.
- Checks against 10+ external blacklists, including FireHOL, IPsum and the Spamhaus DROP list.
- Suggested thresholds for allow, CAPTCHA, verify or block, which you can adjust.
- A bulk portal: upload a CSV or TXT of IPs and download an enriched report. Reports are auto-deleted after 30 days and use the same allowance as API calls.
- EU and US API nodes.
Pricing on AppSumo (9 November 2026)
| Codes | Price | Monthly requests |
|---|---|---|
| 1 | $79 | 25,000 |
| 2 | $158 | 50,000 |
| 3 | $237 | 100,000 |
| 4 | $316 | 250,000 |
All tiers list the same features; the difference is the monthly request allowance. Our arithmetic: Tier 1 is about $3.16 per 1,000 monthly requests of capacity ($79 divided by 25), and Tier 4 is about $1.26 ($316 divided by 250). The listing shows a crossed-out $750 reference price, which is AppSumo’s own comparison and not something we verified. It is refundable for 60 days. At the time we read it the page showed 2 reviews and 111 purchases.
Who it fits
- Developers adding fraud checks to signup or checkout.
- Ecommerce owners seeing card testing or fake accounts.
- Agencies and IT teams who want to enrich IP lists in bulk.
Who should skip it
- Anyone without a developer, since the main use is an API call.
- Sites that need device fingerprinting or behavior analysis; an IP score will not cover that.
- Very high-traffic apps that would exceed 250,000 lookups a month.
Things to check before buying
Confirm whether a request counts for every lookup or only new IPs, and how fast you would hit your monthly cap. Test the false-positive rate on your own real traffic, because VPN users are not always fraudsters. Use the 60-day refund window for this.

Bottom line
Scamalytics is a focused, established tool at a low lifetime price, and the 60-day refund lowers the risk. Treat the score as one input next to rules and manual review, and size the tier to your lookup volume.
