The short version

  • Only Snyk has a free tier, so it costs nothing to try first.
  • Each has a real cost: Snyk free plan has strict test limits across all modules: Open Source (200), Code (100), Infrastructure as Code (300), Container (100) tests per month; 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.
  • They diverge on capability: Snyk covers Open source security, Unit21 covers No-code rule builder.
  • 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.

Snyk

  • Free plan has strict test limits across all modules: Open Source (200), Code (100), Infrastructure as Code (300), Container (100) tests per month
  • Free and Team plans count only contributing developers making commits within 90 days; public contributions do not count
  • Enterprise plan requires custom pricing and sales contact

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.

Answered from the vendors’ own pages

Snyk: How much does Snyk cost?

Snyk offers a free plan with limited tests, Team plan at $25/month per contributing developer, Ignite at $1260/year, and custom Enterprise pricing. Contributing developers are those who made commits to private repos within the last 90 days.

Source
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.

Snyk: What does Snyk's Team plan include?

The Team plan at $25/month includes 1000 Code tests, up to 100 projects, Jira integration, next business day support, and all features from the free plan including SCA, SAST, IaC and Container scanning.

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.

Snyk: Is there a free version of Snyk?

Yes, Snyk offers a free plan with full platform access including SCA, SAST, IaC and Container scanning. The free tier includes 200 Open Source tests, 100 Code tests, 300 IaC tests, 100 Container tests, and up to 5 projects.

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.
