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.; GNU Emacs steep learning curve for its default keybindings and Lisp-based configuration.
  • They diverge on capability: Deep Code covers DeepSeek-backed agent, GNU Emacs covers Emacs Lisp Extensibility.
  • 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.

GNU Emacs

  • Steep learning curve for its default keybindings and Lisp-based configuration.
  • Default UI looks dated compared to modern editors without heavy customization.
  • Performance can lag on very large files compared to newer editors.
  • Discoverability of features is poor without prior familiarity or external guides.

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
GNU Emacs: Is GNU Emacs free, including for commercial use?

Yes, Emacs is free software released under the GNU General Public License, which allows anyone to use, study, modify, and redistribute it, including commercially.

Source
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
GNU Emacs: How do I install Emacs?

On Linux it is available via package managers like apt-get, pacman, dnf, or zypper; on macOS via Homebrew or MacPorts; on Windows via an installer or zip from GNU mirrors; and on Android via F-Droid or GNU FTP.

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
GNU Emacs: What platforms does Emacs support?

Emacs runs on GNU/Linux, FreeBSD, NetBSD, OpenBSD, Haiku, macOS, MS Windows, Android (versions 2.2 to 15.0), Solaris, and MS-DOS/FreeDOS.

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
GNU Emacs: How is Emacs extended with packages?

Emacs is customized and extended through its Emacs Lisp dialect, with thousands of community packages distributed via repositories like MELPA that add language modes and tools.

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.

Source
GNU Emacs: Where can I get source code or development builds?

Emacs source code and development builds are hosted at savannah.gnu.org, in addition to stable releases distributed through GNU mirrors.
