The short version

  • Only React 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; React jSX requires a build step using Webpack, Babel, or other transpilers to convert to browser-executable JavaScript

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

React

  • JSX requires a build step using Webpack, Babel, or other transpilers to convert to browser-executable JavaScript
  • Routing and state management are separate dependencies, not included in core library
  • Configuration complexity for advanced features like server-side rendering without a meta-framework
  • Requires choosing and configuring build tools and development environment setup

Answered from the vendors’ own pages

React: Is React free to use commercially?

Yes. React is distributed under the MIT open-source license, which permits free usage for both personal and commercial projects without licensing fees or restrictions.

Source
React: Does React support TypeScript?

Yes. React works seamlessly with TypeScript for type-safe component development. TypeScript provides static type checking for React components, props, and state, improving code reliability and developer experience.

Source
React: Do I need a build step to use React?

If you use JSX, yes. JSX requires transpilation by a build tool like Webpack and Babel before browsers can execute it. However, React can be used without JSX by calling React.createElement directly, which does not require a build step.

Source
React: Can I build offline-capable applications with React?

Yes. React supports building Progressive Web Apps (PWAs) with service workers and IndexedDB for offline functionality. Create React App includes service worker setup, though it must be manually enabled for production use.
