6 free alternatives to FraudLabs Pro

Antideo's free plan is simple and permanent: 10 API requests per hour, plus HTTP and HTTPS access, email support, and basic limits that stay in place on the free account. It is built around IP location, reputation, email validation, and phone validation rather than order screening. Where it helps is the no-cost, always-on access to a focused validation API that can fit lightweight workflows or prototype checks. Where it trails FraudLabs Pro is breadth, since it does not provide fraud scoring, rule counts, blacklists, or order transaction screening. Switch if you want a small free verification API and do not need full checkout fraud tooling.

• Beats FraudLabs Pro: Permanent free access with clear HTTP and HTTPS support
• Falls short: Much narrower fraud-screening scope and only 10 requests per hour
• Who should switch: Switch to it if you want a tiny always-free validation API for light enrichment or prototyping.

ProxySentry's free Developer plan gives you 10,000 requests per month, basic proxy detection, and community support. That makes it a larger free monthly pool than FraudLabs Pro's 500 queries, but it is also much narrower in purpose. Its free tier focuses on identifying proxy use and related abuse signals from IP analysis, which is useful when proxy detection is the main problem you need to solve. It falls short of FraudLabs Pro on multi-signal order screening because you do not get billing, shipping, payment, email, blacklist, velocity, or rule-management features in the free tier. Choose it if proxy abuse is your primary concern and you need more free request volume.

• Beats FraudLabs Pro: 10,000 requests per month instead of 500 queries per month
• Falls short: No order-fraud workflow features like rules, blacklists, or payment checks
• Who should switch: Switch to it if proxy detection is the main control you need and monthly volume matters more than workflow depth.

APIVerve's free tier includes 1,000 monthly credits, access to all APIs in the catalog, limited rate limiting, and a set of lightweight developer tools such as basic Studio access, one static JSON bin, and one static mock API endpoint. It also includes limited GraphQL, MCP, Zapier, Make, and Power Automate integration, though support is not included. The free plan is broader than FraudLabs Pro in surface area because it gives access to a large API catalog, but it is not a fraud-specific product. It loses on direct fraud screening, rules, blacklists, and SMS credits. Pick it if you want a general API platform and can assemble your own workflow.

• Beats FraudLabs Pro: Access to a broad API catalog plus 1,000 monthly credits
• Falls short: Not a fraud-detection service and no built-in fraud rules or scoring workflow
• Who should switch: Switch to it if you want one free account for many APIs rather than a purpose-built fraud screen.

IPWho's free plan includes 2,000 requests per day, world-class latency, and the full Launch feature set. It is one of the larger free geolocation ceilings in this set, and it is perpetual. The tradeoff is that it is strictly for IP geolocation, not payment or order fraud review, and it also blocks commercial use, support, and SLA guarantees. Compared with FraudLabs Pro, it gives far more room for IP lookups but far less fraud logic. Use it when you mainly need fast geolocation data at higher free volume and do not need checkout screening, blacklists, or rules.

• Beats FraudLabs Pro: 2,000 requests per day and world-class latency
• Falls short: No commercial use and no fraud-screening features beyond IP data
• Who should switch: Switch to it if IP lookup volume is the bottleneck and your use is non-commercial or internal.

IPGeolocation.io's free plan gives you 1,000 API credits per day for life, no credit card, no overages, and core geolocation data such as country metadata, currency data, ASN basics, organization data, and coupled time zone data. It also includes standalone access to Time Zone, Astronomy, and User Agent APIs. That makes it useful when you need a generous, recurring free geolocation plan with a few extra APIs on the side. It falls short of FraudLabs Pro because it does not cover payment fraud scoring, rule logic, blacklists, or order-specific validation. Switch if you want broad geolocation coverage with a predictable free ceiling.

• Beats FraudLabs Pro: 1,000 credits per day with no overages and no card required
• Falls short: No fraud scoring, blacklist workflow, or order transaction screening
• Who should switch: Switch to it if your main need is recurring geolocation data rather than fraud detection.

IP2Location.io's free plan includes 50K IP Geolocation API queries per month, 500 Domain WHOIS queries per month, 50 Hosted Domain queries per month, 11 IP attributes, daily database updates, standard support, and basic geolocation data. It also includes basic proxy detection with open proxies detection. This is the most structured geolocation-oriented free tier here, with multiple quotas and daily updates, but it still does not offer FraudLabs Pro's order-fraud rules, scoring, blacklist workflow, or SMS credits. If you want a free geolocation and proxy baseline with a broader quota mix, this is a strong fit.

• Beats FraudLabs Pro: 50K geolocation queries per month plus WHOIS and hosted-domain quotas
• Falls short: No order-fraud workflow, fraud score, or SMS verification credits
• Who should switch: Switch to it if you want the largest free geolocation quota mix and only light proxy screening.
