The short version
- Only Yarn has a free tier, so it costs nothing to try first.
- Each has a real cost: Feedzai pricing is per transaction with an annual minimum, so a bank with seasonal or growing volume commits to a floor it may not use and pays overage above the band.; Yarn yarn 2+ (Berry) has limited ESM support which can be a constraint for some projects
- 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.
Feedzai
- Pricing is per transaction with an annual minimum, so a bank with seasonal or growing volume commits to a floor it may not use and pays overage above the band.
- It sits in the authorisation path, which makes every upgrade a change-controlled event with rollback plans, and the operational burden falls on the bank rather than the vendor.
- Out of the box models need months of the customer own labelled fraud history before they beat the rules they replace, so the value case starts late.
- AML and fraud are licensed as separate modules, so institutions expecting one platform fee find the transaction monitoring capability is a second line item.
- The buyer profile is large institutions, so smaller banks and fintechs face minimums that make per-transaction economics unattractive below significant scale.
Yarn
- Yarn 2+ (Berry) has limited ESM support which can be a constraint for some projects
- Smaller ecosystem and community compared to npm, though still substantial

Answered from the vendors’ own pages
Feedzai: Can Feedzai run on-premises?
Yes. On-premises and private cloud deployments are supported, which is why it appears in markets where transaction data cannot legally leave the country.
Yarn: What is Yarn's main advantage over npm?
Yarn downloads packages in parallel, significantly reducing installation time. It uses a yarn.lock file for deterministic installs, ensuring identical package versions across machines and preventing version conflicts common with npm.
SourceFeedzai: Does it cover AML as well as fraud?
It does, but transaction monitoring is a separately licensed module. Assume two line items if you want both.
Yarn: Can I use Yarn in offline environments?
Yes, Yarn supports secure offline environments. The yarn.lock file enables reproducible installs without requiring new downloads.
SourceFeedzai: How fast are decisions?
Designed for the authorisation window, typically tens of milliseconds. This is the constraint that rules out batch scoring architectures.
