Unit21 vs Yarn
Unit21
Cybersecurity
No-code fraud and AML risk operations platform for fintechs and neobanks

- On request
- Free plan
- No
Yarn
Developer Tools
Fast, reliable, and secure dependency management
- From
- Free
- Free plan
- Yes
The short version
- Only Yarn has a free tier, so it costs nothing to try first.
- Each has a real cost: 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.; 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.
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.
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

Of those, a neobank whose sponsor bank requires a documented monitoring programme before it will keep the bin sponsorship and a crypto exchange needing sar filing and case management without building an internal compliance engineering team are not what Yarn is typically brought in for.

- Unit21 covers No-code rule builder, Case management, SAR filing, Backtesting.
Answered from the vendors’ own pages
Unit21: Do we need engineers to run it?
Only for the initial data integration. After that the design intent is that risk and compliance staff author and deploy rules themselves.
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.
SourceUnit21: 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.
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.
SourceUnit21: 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.
