Solid.js
Solid.js is an open source JavaScript framework that combines a React-like component syntax with fine-grained reactivity, updating the DOM directly without a virtual DOM.
What Solid.js is used for
Solid is used to build highly responsive web interfaces where update performance matters. Components look much like React function components with JSX, but they run only once: instead of re-rendering on every state change, Solid's signals track exactly which DOM nodes depend on which values and update only those. This fine-grained model consistently places Solid among the fastest frameworks in independent benchmarks. SolidStart, its full-stack framework, adds routing and server rendering, and Solid's signal concept has influenced reactivity work across the wider ecosystem, including Angular and Svelte.
Why it matters for business software
For most business applications, framework speed is not the bottleneck, but for data-dense dashboards, real-time views, and interfaces running on constrained devices, Solid's efficiency is a genuine advantage. Its React-like syntax keeps the learning curve modest for teams with React experience. The trade-offs are a smaller ecosystem, fewer ready-made component libraries, and a thinner hiring pool, so it fits teams that will own the codebase long term and can justify performance as a requirement rather than a preference.
How Wizcoder AI Labs uses it
We evaluate Solid for performance-critical interfaces within our custom software development engagements and apply its reactivity lessons across our frontend stack, even on projects that ultimately ship with React.
