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.
ESLint
- Slow performance on large codebases compared to newer tools like Oxlint and Biome
- Complexity in configuration from scratch, particularly for TypeScript support
- Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

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.
SourceESLint: Does ESLint automatically fix code issues?
Many problems ESLint finds can be automatically fixed via the --fix flag. ESLint fixes are syntax-aware so you won't experience errors introduced by traditional find-and-replace algorithms.
SourceDeep 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.
SourceESLint: How much does ESLint cost?
ESLint is completely free and open-source software maintained by the OpenJS Foundation. The project accepts voluntary donations from sponsors.
SourceDeep 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.
SourceESLint: Can I write custom ESLint rules?
Yes. You can develop custom rules that work alongside built-in functionality through ESLint's plugin system, allowing complete customization for your project needs.
SourceDeep 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.
SourceDeep 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.
