  • 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.; RubyMine no permanently free tier for commercial use; requires an ongoing subscription.
  • They diverge on capability: Deep Code covers DeepSeek-backed agent, RubyMine covers Rails-aware coding assistance.
  • 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.

RubyMine

  • No permanently free tier for commercial use; requires an ongoing subscription.
  • More resource-intensive than lightweight editors such as Sublime Text.
  • Focused primarily on Ruby, so polyglot teams may prefer IntelliJ IDEA Ultimate with plugins instead.
  • Startup time can be slower than simpler text editors on older hardware.

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.
