React vs Svelte
No clear leader: React (79.5) and Svelte (78.3) are within the 5-point margin; treat as a tie. The attribute-by-attribute breakdown below, with a source and date on every value, is the honest way to compare them.
Capabilities

What each one is
The product in its own terms, so the numbers below have context.
React
A library that enables developers to construct user interfaces using individual components as building blocks. React components are JavaScript functions that receive data and render the appropriate output, supporting both web applications and native mobile development through frameworks.
Svelte
A framework with an integrated compiler that lets developers create streamlined components using standard HTML, CSS, and JavaScript, minimizing runtime overhead in the browser.
Pricing
List pricing as published by each vendor, with the date we read it. Always verify at the source before you buy.
Platform & deployment
