The short version

  • Only Stripe has a free tier, so it costs nothing to try first.
  • Each has a real cost: Sardine signal quality depends on the SDK being embedded in your own web and mobile clients, so fraud improvements become dependent on your app release cycle and any coverage gap is a blind spot.; Stripe requires developer setup and API integration for most use cases
  • They diverge on capability: Sardine covers Device intelligence, Stripe covers Payment processing.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Sardine

  • Signal quality depends on the SDK being embedded in your own web and mobile clients, so fraud improvements become dependent on your app release cycle and any coverage gap is a blind spot.
  • Behavioural and device telemetry collection needs a documented lawful basis under GDPR, and EU privacy reviews frequently delay rollouts that were scoped as engineering work.
  • Pricing is per session or per active user, so a consumer product with many low value sessions pays in proportion to traffic rather than to fraud exposure.
  • As a younger private company it lacks the enforcement-tested audit history that a bank examiner expects, which makes it a harder sell inside a regulated bank than inside a fintech.
  • It is strongest on session-time signals and weaker as a system of record for long horizon AML typologies, so larger institutions end up running it alongside a traditional monitoring platform rather than instead of one.

Stripe

  • Requires developer setup and API integration for most use cases
  • Dispute fee of $15 per chargeback is standard industry cost
  • Limited offline payment capabilities

Answered from the vendors’ own pages

Sardine: Does Sardine do document verification?

It focuses on device, behavioural and transaction signals, and integrates identity verification providers rather than being one. Treat it as complementary to a KYC vendor.

Stripe: What are Stripe's transaction fees?

Standard US rates are 2.9% plus 30 cents for online card payments, 2.7% plus 5 cents for in-person, 3.4% plus 30 cents for keyed/phone transactions, and 0.8% capped at $5 for ACH payments.

Source
Sardine: What does it need from us to work?

An SDK in your web and mobile applications plus transaction feeds. Without the client side collector you lose the signals that differentiate it.

Stripe: How many currencies and countries does it support?

Stripe accepts 135+ currencies and supports payment acceptance in 40+ countries through Stripe Connect, enabling sellers to onboard and receive payouts in minutes.

Source
Sardine: Is pricing published?

No. It is quoted, typically per session or per monthly active user with an annual volume commitment.

Stripe: What payment methods are supported?

Stripe supports dozens of payment methods including credit/debit cards, ACH transfers, and local payment options, with additional support through partnerships with Meta and Google.

Source
Stripe: Are there monthly fees or contracts?

No. Stripe charges no monthly fees or contracts, only per-transaction fees and dispute fees, making costs fully transparent and variable.
