  • Each has a real cost: SolidJS much smaller ecosystem than React, so many problems have no off-the-shelf library; Svelte licensed under the MIT License per svelte.dev; as open source software it has no paid tier or vendor price to compare
  • Prices and features above were last checked on 29 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

SolidJS

Where each one falls short

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

SolidJS

  • Much smaller ecosystem than React, so many problems have no off-the-shelf library
  • The React-like syntax is misleading: components run once, and React habits produce subtle bugs
  • Smaller hiring pool and fewer learning resources than the mainstream frameworks

Svelte

  • Licensed under the MIT License per svelte.dev; as open source software it has no paid tier or vendor price to compare
  • Svelte is a compiler rather than a runtime library by design, per svelte.dev, so components must be compiled ahead of time and cannot be interpreted directly in the browser without a build step

Answered from the vendors’ own pages

SolidJS: Is SolidJS free?

Yes, open source under the MIT licence.

Svelte: How much does Svelte cost?

Svelte is completely free and open source under the MIT license. There are no paid plans, subscriptions, or licensing fees for any use case.

Source
SolidJS: Is SolidJS just React without the virtual DOM?

The syntax is similar but the model is not. Solid components run once and reactivity is fine-grained, so patterns that are correct in React can be wrong in Solid.

Svelte: Who maintains and funds Svelte?

Svelte is backed by Vercel as the primary corporate sponsor, along with community donors and corporate sponsors including GitHub, Cohere, Sanity, Sentry, and Sourcegraph. Development is maintained by full-time and part-time open source maintainers.

Source
SolidJS: Why is SolidJS fast?

It compiles away much of the framework and updates individual DOM nodes directly, rather than re-rendering components and diffing a virtual DOM.
