The short version

  • 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.; Ruby on Rails licensed under the MIT License per rubyonrails.org; as open source software it has no paid tier or vendor price to compare

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.

Ruby on Rails

  • Licensed under the MIT License per rubyonrails.org; as open source software it has no paid tier or vendor price to compare
  • The framework is Ruby-only by design, per rubyonrails.org's own description of its convention over configuration approach, requiring the Ruby runtime rather than supporting alternate languages

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.

Source
Ruby on Rails: Is Ruby on Rails free?

Yes, Ruby on Rails is free and open-source, licensed under the MIT License. There are no costs associated with using or distributing the framework.

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.

Source
Ruby on Rails: What is Ruby on Rails licensed under?

Ruby on Rails is licensed under the MIT License, a permissive open-source license that allows commercial and private use.

Source
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.

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
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.
