The short version
- Each has a real cost: Deno the runtime itself is MIT licensed per the project's GitHub repository (denoland/deno LICENSE.md) with no cost, but Deno Deploy's free tier caps at 1 million requests and 15 CPU hours per month, per deno.com/deploy/pricing (Aug 2026); Next.js opinionated architecture reduces flexibility compared to using React alone with separate libraries

Deno
- The runtime itself is MIT licensed per the project's GitHub repository (denoland/deno LICENSE.md) with no cost, but Deno Deploy's free tier caps at 1 million requests and 15 CPU hours per month, per deno.com/deploy/pricing (Aug 2026)
- Deno Deploy Pro at $20 per month charges $2 per additional million requests and $0.05 per additional CPU hour once the included quota is exceeded, per deno.com/deploy/pricing
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
Next.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.
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.
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.
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.
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.
