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.; Helix no official GUI application yet, so it requires comfort with terminal workflows.
  • They diverge on capability: Deep Code covers DeepSeek-backed agent, Helix covers Multiple Selections.
  • 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.

Helix

  • No official GUI application yet, so it requires comfort with terminal workflows.
  • Plugin ecosystem is far smaller than Vim's or Neovim's, limiting customization.
  • Keybindings differ from both Vim and Kakoune, adding a learning curve for users of either.
  • Configuration is more limited than Neovim's Lua-based extensibility.

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
Helix: Is Helix free to use?

Yes, Helix is free and open source, licensed under the Mozilla Public License 2.0 (MPL-2.0), with no paid tiers or subscriptions.

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
Helix: How do I install Helix?

Install via your operating system's package manager, or download pre-built binaries from GitHub Releases; the nightly version requires building from source.

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
Helix: Does Helix support plugins?

Not yet. Helix currently has no plugin system, though the project intends to add one eventually; it instead ships with built-in LSP and tree-sitter support out of the box.

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
Helix: How do I configure Helix?

Helix ships with sane modern defaults requiring much less config-file fiddling than Vim, though settings can still be customized in a config.toml file.

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
Helix: Where can I get help or support?

Support is community-driven via GitHub for code and issues, the Matrix chat for discussion, and OpenCollective for funding ongoing development.
