The short version

  • Only Sweep has a free tier, so it costs nothing to try first.
  • Each has a real cost: Sweep limited to JetBrains IDEs only, not available for VS Code or other editors; 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: Sweep covers Autocomplete, Unit21 covers No-code rule builder.
  • Prices and features above were last checked on 1 September 2026.

  • A payments startup where the fraud lead needs to ship a new rule the same day a new attack pattern appearsnot Sweep
  • A lender consolidating fraud alerts from three point tools into one investigator queue with a single audit trailnot Sweep

Where each one falls short

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

Sweep

  • Limited to JetBrains IDEs only, not available for VS Code or other editors
  • Free tier limited to 1,000 autocompletes per month
  • API credit consumption varies by feature usage
  • Performance dependent on codebase size and indexing quality

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

Sweep: What programming languages does Sweep support?

Sweep works with all programming languages supported by JetBrains IDEs, including Python, Java, JavaScript, Go, Kotlin, C++, and many others.

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.

Sweep: Does Sweep retain my code data?

No. Sweep is SOC 2 Type II certified with zero data retention. Code is processed for suggestions but not stored.

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.

Sweep: Can I cancel my Sweep subscription anytime?

Yes. You can cancel your subscription at any time from your account settings with no long-term commitments or cancellation fees.

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.
