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

WebStorm

  • JetBrains WebStorm is sold as an annual subscription rather than a one-time purchase: commercial price is $199 per year (USD), and personal price starts at $299 in year one, dropping to $239 in year two and $179 from year three onward with continuous renewal
  • If the subscription lapses, use of new versions stops; JetBrains grants a fallback license only for the last version used while the subscription was active, per its published buy page

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.

WebStorm: Is there a free version of WebStorm?

Yes, WebStorm is free for non-commercial use and includes access to JetBrains AI with a free tier.

Source
Feedzai: 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.

WebStorm: What is the cost of a commercial WebStorm license?

The page references a testimonial mentioning 70 euros as a cost, though specific current pricing requires visiting the dedicated pricing page.

Source
Feedzai: How fast are decisions?

Designed for the authorisation window, typically tens of milliseconds. This is the constraint that rules out batch scoring architectures.

WebStorm: How does JetBrains AI licensing work?

Users can pay with JetBrains AI credits, bring their own AI subscriptions and API keys to avoid vendor lock-in, or use the free tier included with WebStorm.

Source
WebStorm: What features does the free tier include?

The free tier includes the smart code editor, navigation tools, integrated developer tools, and customization options.
