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.
Next.js
- Opinionated architecture reduces flexibility compared to using React alone with separate libraries
- Required build and deployment infrastructure adds complexity for beginners
- Server Components paradigm represents significant mental model shift from traditional client-side React
- Async request handling in version 15 requires relearning APIs (params, cookies, headers now require await)
- Lock-in to Vercel ecosystem for optimal performance, though other platforms are supported

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.
SourceNext.js: Is Next.js free?
Yes. Next.js is free, open-source software built on React and maintained by Vercel. The framework itself has no licensing costs. Hosting and deployment fees depend on your chosen platform.
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.
SourceNext.js: What are the key features of Next.js?
Next.js includes Server-Side Rendering (SSR), Static Site Generation (SSG), Incremental Static Regeneration (ISR), file-based routing, API routes, automatic code splitting, image optimization, and built-in performance optimizations that typically result in 90+ Lighthouse scores.
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.
SourceNext.js: Can I host Next.js applications for free?
Yes. Vercel offers a free Hobby tier for Next.js applications. Netlify and other platforms also provide free hosting tiers with generous bandwidth and build limits for testing and personal projects.
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.
SourceNext.js: Does Next.js require a build step?
Yes. Next.js requires a build step (next build) before deployment to production. This compiles your application and prepares it for optimal performance, though local development runs directly without this step.
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.
SourceNext.js: What is React Server Components in Next.js?
React Server Components are a feature in Next.js that allow components to run on the server, reducing JavaScript sent to clients and improving security by keeping sensitive data server-side. They became stable in Next.js 15.
