The short version

  • Only Next.js has a free tier, so it costs nothing to try first.
  • Each has a real cost: Azure Functions consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that; Next.js opinionated architecture reduces flexibility compared to using React alone with separate libraries

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Azure Functions

  • Consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that
  • The newer Flex Consumption plan's free grant is smaller still, at 250,000 executions and 100,000 GB-seconds per month
  • Premium plan avoids per-execution charges but bills continuously for allocated core seconds and memory regardless of invocation volume
  • Memory is rounded up to the nearest 128 MB and execution time to the nearest 1 ms for billing, so small overages round upward

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

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.

Source
Next.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.

Source
Next.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.

Source
