Stripe Radar

Stripe Radar is a fraud and abuse protection service for businesses handling payments through Stripe, with API risk signals also available to businesses using other processors. It is best suited to Stripe merchants and platforms that want fraud screening within their payment flow. Its broad payment coverage is a strong reason to choose it; businesses needing advanced controls should expect to pay for them.

Overview

Radar uses machine learning to block fraudulent payments, flag suspicious accounts and help prevent customer abuse in real time. Stripe says its AI draws on more than 70 trillion data points across its network. For businesses already processing payments with Stripe, Radar works in the background without additional setup, making it a practical fit for those who want payment screening within that existing flow.

Coverage extends beyond cards to supported bank debits, buy now pay later options, crypto, digital wallets, real-time payments and cash vouchers. Radar can also be used with Stripe Connect; Stripe says no additional integration is required for Connect accounts onboarded to a platform. Businesses processing through other providers can use APIs to access risk signals, but should distinguish that from Radar's background protection for Stripe payments.

Key features

Controls depend on the plan

Radar Lite includes AI fraud prevention for card payments and card-testing fraud alerts. Standard adds out-of-the-box fraud protection across supported payment methods and analytics. Plus and Pro include risk scores, custom rules and backtesting, manual reviews, risk preferences, adaptive 3D Secure and advanced fraud analytics. Dynamic risk thresholds are reserved for Pro, so businesses that need that control cannot get it on Plus.

Pro adds signals for bot, multi-account, account-sharing and pay-as-you-go abuse, as well as free-trial abuse protection. That makes it the clearest fit for businesses facing abuse beyond straightforward payment fraud, though the Pro price is a substantial step up from Standard.

Risk signals beyond Stripe payments

Radar can provide risk signals through APIs to businesses using other payment service providers. Enterprise customers can get tailored recommendations, Radar risk signals and protection for payments not processed on Stripe. This extends Radar's potential use beyond Stripe's payment flow, but the enterprise plan is custom priced.

Pricing

Radar is freemium. Lite is included at no additional charge for businesses on standard payments pricing. Paid plans start at $10 per month; the prices below are starting prices, and the exact fit depends on the controls and business type required.

Lite is the lowest-cost choice, but its stated fraud prevention is limited to card payments. Standard is the step up for merchants seeking protection across supported payment methods. Plus is aimed at businesses that need custom rules and more control over risk tolerance, while Pro adds abuse signals and dynamic risk thresholds. Platform and marketplace plans cost more at each tier and add account- and platform-oriented capabilities such as fraudulent account identification or reserves. Enterprise suits businesses seeking tailored recommendations and risk signals, with pricing arranged through sales.

Platforms

Radar supports Android, iOS, web and API use. Its API risk-signal option is relevant to businesses using other processors; the background setup advantage applies to businesses already processing payments with Stripe.

Who it's for

Radar is a natural choice for Stripe merchants who want fraud screening integrated into their existing payment operation, especially when they accept multiple supported payment methods. Platforms and marketplaces can consider the dedicated plans, while businesses with significant account, bot or free-trial abuse concerns should look to Pro. It is less compelling for a business seeking advanced controls at the lowest possible cost, since risk scores and custom rules start at Plus and dynamic risk thresholds require Pro.

Stripe describes Radar as built for platforms, marketplaces and AI companies, and offers enterprise recommendations and custom pricing. Users remain responsible for how they use Radar data and for decisions made from it, so its risk signals do not transfer that responsibility to Stripe.

Pros and cons

• Pros: Existing Stripe users can run Radar without additional setup, keeping fraud controls in the payment flow they already use.
• Pros: Supported payment coverage includes methods beyond cards, while Plus and Pro add controls such as custom rules and backtesting.
• Pros: Connect accounts onboarded to a platform require no additional integration, according to Stripe.
• Cons: Lite's stated fraud prevention is card-focused; broader payment-method protection starts with Standard.
• Cons: Risk scores and custom rules require Plus or Pro, and dynamic risk thresholds require Pro.
• Cons: Users retain responsibility for decisions based on Radar data, even when relying on its risk signals.

Verdict

Choose Stripe Radar if you already process payments with Stripe and want fraud controls spanning supported payment methods without adding a separate setup step. Its integrated starting point and upgrade path to richer risk controls are the main draw. Look elsewhere if you need advanced controls without moving beyond a low-cost tier, or if you do not want to retain responsibility for decisions based on risk data.
