Open source

Compiler-based UI framework that ships no runtime to the browser.

PriceFree

Why we recommend it

Because it compiles away at build time, the shipped bundle is markedly smaller than React or Vue equivalents — which matters for design-led sites where load time is part of the experience.

Strengths

  • No framework runtime in the shipped bundle
  • Genuinely less boilerplate than React
  • Built-in transitions and animation primitives

Drawbacks

  • Smaller ecosystem and job market than React
  • Fewer third-party component libraries
  • Svelte 5's runes syntax changed established patterns
