Where each one falls short

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

Unit21

  • It is built for fintech scale rather than card issuer scale, so organisations reaching very high transaction volumes generally re-evaluate against heavier platforms and face a migration
  • No-code rule authoring shifts power to the risk team, which is the point, but without governance it produces rule sprawl that nobody can explain to an examiner two years later
  • Detection quality depends on the signals you feed it, so a thin integration produces thin results and the platform cannot compensate with proprietary consortium data the way larger vendors do
  • Pricing is quoted by volume with an annual commitment, so a fintech whose growth stalls pays for headroom it did not use
  • SAR filing coverage is oriented to United States FinCEN reporting, so firms filing in the United Kingdom, European Union or Asia handle those submissions outside the tool

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

Unit21: Do we need engineers to run it?

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

Source
Unit21: Does it file SARs?

Yes, it generates and electronically files suspicious activity reports to FinCEN. Non-US regimes are not covered to the same depth.

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
Unit21: Can we test a rule before it goes live?

Yes. Backtesting against historical data to see projected alert volume is one of the more useful parts of the product, because alert volume is the real cost.

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
