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

Tenable

  • Pricing starts at $3500/year for Tenable One VM, expensive for small organizations
  • Many enterprise features require custom quote and sales engagement
  • Cloud Exposure, OT Exposure, and other modules have no published pricing
  • Multi-year contracts common, limiting flexibility
  • Setup and configuration complexity for enterprise deployments
