The short version

  • Each has a real cost: Aider requires comfort working in a terminal rather than a graphical IDE; 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.
  • They diverge on capability: Aider covers Multi-LLM support, Deep Code covers DeepSeek-backed agent.
  • 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.

Aider

  • Requires comfort working in a terminal rather than a graphical IDE
  • Has no hosted or managed version, so users must supply and pay for their own LLM API access separately
  • Depends heavily on the chosen underlying model's quality, so results vary by which LLM is configured
  • Lacks a built-in autonomous multi-step task runner comparable to agent-style products

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.

Answered from the vendors’ own pages

Aider: Is Aider free to use?

Aider itself is free and open source, released under the Apache 2.0 license. Users must separately supply and pay for API access to the LLM they choose to use with it.

Source
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
Aider: Which LLMs can I use with Aider?

Aider connects to OpenAI, Anthropic, Gemini, GROQ, DeepSeek, Ollama, Azure, Cohere, xAI, GitHub Copilot, Vertex AI, Amazon Bedrock, OpenRouter and most other LLM providers via API keys.

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
Aider: Can I use Aider for free without paying for an LLM API?

Yes, Aider can be used at no cost through OpenRouter's free model access (subject to daily usage limits) or Google's Gemini 2.5 Pro Exp, which the docs note performs well without a paid API key.

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
Aider: How does Aider handle version control?

Aider automatically stages and commits each change it makes to a connected git repository, generating a descriptive commit message for every edit so changes stay reviewable and reversible.

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.
