The short version

  • Each has a real cost: Plaid no dollar amount is published for any product, and the pricing page states no per request rate or minimum commitment; 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.
  • They diverge on capability: Plaid covers Bank account linking, Sardine covers Device intelligence.
  • 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.

Plaid

  • No dollar amount is published for any product, and the pricing page states no per request rate or minimum commitment
  • Three different billing models apply depending on the product, being one time per connected account, monthly per connected account, and per successful API call
  • That mix means total cost depends on which products are combined rather than on a single unit
  • Discounted rates require the Growth plan, which is a 12 month commitment

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.

Answered from the vendors’ own pages

Plaid: How much does Plaid cost?

Plaid does not publish per request rates. It offers Pay as You Go with no upfront commitment, a Growth plan on a 12 month commitment with discounts, and a Custom plan priced on volume. Figures come from its sales team.

Source
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.

Plaid: How does Plaid bill for its products?

Plaid uses three billing shapes: one time fee products charged once per connected account, subscription products charged monthly per connected account, and per request products charged a flat fee for every successful API call.

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.

Plaid: Can I test Plaid for free?

Yes. Plaid's Limited Production service allows up to 200 API calls with each available product using live data, before any commitment. Plaid is also free for the consumers whose accounts are connected.

Source
Sardine: Is pricing published?

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