The short version
- Only Deep Code has a free tier, so it costs nothing to try first.
- Each has a real cost: Deep Code model choice is narrow. Bring your own key covers DeepSeek-V4-Pro and Flash plus the GLM and Mimo coding plans, and no frontier model from OpenAI, Anthropic or Google.; 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: Deep Code covers DeepSeek-backed agent, Unit21 covers No-code rule builder.
- Prices and features above were last checked on 15 September 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Deep Code
- Model choice is narrow. Bring your own key covers DeepSeek-V4-Pro and Flash plus the GLM and Mimo coding plans, and no frontier model from OpenAI, Anthropic or Google.
- The Pro tier caps included usage at 100 Pro Credits per day rather than offering an unmetered plan.
- Bring your own key is a paid feature, so the free tier cannot be pointed at your own DeepSeek account.
- Desktop only, with no editor extension, web version or team seat management as of September 2026.
- A small, young vendor with no independent review coverage yet, so there is nothing outside the vendor's own site to corroborate the cost claim.
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
Deep Code: Which models does Deep Code run on?
DeepSeek V4 family models, with the vendor's headline built around DeepSeek V4.1. The free tier's included credits run on DeepSeek-V4-Flash. Paid users bringing their own key can also use DeepSeek-V4-Pro, the GLM Coding Plan and the Mimo Coding Plan.
SourceUnit21: 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.
Deep Code: What does Deep Code cost?
There are two tiers. Free is $0 per month and includes session management, the file explorer, snippets, voice input and weekly free credits on DeepSeek-V4-Flash. Pro is $5 per month and adds 100 daily Pro Credits plus bring-your-own-key support for multiple models.
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.
Deep Code: Do I need my own API key to use it?
No. The free tier includes weekly credits and needs no credit card, so the app works without a key. Bring your own key is available on the $5 per month Pro tier and covers DeepSeek-V4-Pro, DeepSeek-V4-Flash, the GLM Coding Plan and the Mimo Coding Plan.
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.
Deep Code: Which operating systems does it run on?
Windows, macOS and Linux. It is a desktop application rather than an editor extension, so it runs alongside whatever editor you already use.
SourceDeep Code: Is the 95 percent cheaper claim independently verified?
No. It is the vendor's own figure, based on DeepSeek token pricing against frontier model pricing. Actual savings depend on which model you compare against and how much of your usage falls inside the included credits.
