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.

Zeplin

  • The free plan is limited to 1 project and 100 screens and works only in a personal workspace
  • Free plan AI reviews are capped at 3 per week
  • Role based permissions require the Advanced plan or higher
  • Single sign on, multi factor authentication, activity logs and invoiced billing are Enterprise only
  • Priority 24 hour support is Enterprise only
  • Basic plan caps screens at 1,000 per project and is priced per project rather than per seat
  • Enterprise pricing is by quote with no published rate

Yes, Free and Basic plans allow unlimited team members. Advanced/Enterprise assign roles with Reviewers being free and unlimited.

Source
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.

Source
Zeplin: What can Reviewers do?

Reviewers can view designs and documentation and approve requests, but lack access to developer specs.

Source
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.
