The short version

  • Each has a real cost: Earthly pricing model not published; requires sales contact; React jSX requires a build step using Webpack, Babel, or other transpilers to convert to browser-executable JavaScript
  • They diverge on capability: Earthly covers Policy as code, React covers Component-based architecture.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Earthly

  • Pricing model not published; requires sales contact
  • Earthly Lunar is a recent launch (2025) with limited track record
  • Primarily GitHub-focused; limited integration with other platforms
  • No public documentation on pricing or feature tiers

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

Earthly: What is the difference between Earthfiles and Earthly Lunar?

Earthfiles is an open-source build tool that reached 12,000 GitHub stars and is used by companies like NVIDIA, Intel, and Databricks. Earthly Lunar is a separate governance platform launched in 2025 for enforcing standards across development workflows.

Source
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
Earthly: How does Earthly Lunar enforce standards?

Lunar converts engineering standards, compliance requirements, and processes documented in AGENTS.md files, wikis, and incident postmortems into enforceable guardrails that apply consistently across repositories and development stages.

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
Earthly: What is the pricing for Earthly Lunar?

Pricing is not published on the website. Interested customers should contact Earthly's sales team for current pricing and feature tiers.

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.
