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
Diligent
- The platform is an assembly of acquisitions, with the analytics engine from ACL, risk from Rsam, ethics and third-party diligence from Steele and the board portal from Diligent itself, so cross-module reporting and consistent user experience should be tested in a proof of concept rather than assumed
- Pricing is unpublished and consistently at the top of the market, and organisations that need only one capability, a board portal or an audit analytics tool, generally pay less and get more from a specialist
- Renewal leverage is weak once the board portal is embedded, because directors are the least willing user group to be migrated and that dependency is well understood by the vendor at renewal time
- The analytics engine expects real data skills, and audit teams without an analytics-capable member typically use a fraction of what they licensed while paying for all of it
- Module-by-module implementation means the promised single view of governance and risk usually arrives years after the first purchase, if the later modules are ever funded

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.
SourceDiligent: Is Diligent One the same product as Galvanize?
It contains it. Diligent bought Galvanize, the ACL and Rsam merger, for around one billion dollars in April 2021, and its audit analytics and risk modules are that heritage rebranded into Diligent One.
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.
SourceDiligent: What does Diligent cost?
Not published. It is quoted by module and user, and board portal seats are priced differently from GRC seats. Expect an annual or multi-year enterprise agreement.
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.
SourceDiligent: Can you buy just the board portal?
Yes, Diligent Boards is sold on its own and is the most common entry point. The GRC modules are separate purchases.
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.
SourceDiligent: Does it replace a SOC 2 automation tool?
No. Diligent is aimed at enterprise audit, risk and governance, not at automated evidence collection for security certifications.
Deep 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.
