Why Choose Fidro over Stripe Radar

Catch Fraud Earlier

Stripe Radar evaluates fraud at payment time. Fidro catches it at signup — validating emails, detecting disposable domains, and scoring risk before a transaction ever happens.

Works With Any Payment Processor

Stripe Radar only works with Stripe. Fidro is a standalone API that works with Stripe, PayPal, Braintree, or any payment processor — and beyond payments entirely for signup and account protection.

Email Intelligence Built In

Stripe Radar doesn't validate emails. Fidro detects disposable domains, checks email deliverability, and identifies high-risk email patterns — signals that Radar misses entirely.

Frequently Asked Questions

Is Fidro a good alternative to Stripe Radar?

Fidro complements or replaces Stripe Radar depending on your needs. While Radar is built into Stripe and works automatically, Fidro adds email validation, disposable email detection, and works across any payment processor — not just Stripe.

How is Fidro different from Stripe Radar?

Stripe Radar only works within Stripe and focuses on transaction-level fraud. Fidro catches fraud earlier — at signup, before payment — by validating emails, detecting disposable domains, and analyzing IP reputation. Fidro also works with any payment processor, not just Stripe.

Can I use Fidro and Stripe Radar together?

Yes, many teams use both. Fidro validates users at signup and before checkout, catching disposable emails and high-risk IPs early. Stripe Radar then provides an additional layer of transaction-level fraud detection at payment time.
