A declarative JavaScript library for building user interfaces with fine-grained reactivity and no virtual DOM.
Solid is a declarative JavaScript library for building user interfaces that compiles templates to real DOM nodes instead of using a virtual DOM. It uses fine-grained reactivity to update only the parts of the UI that depend on changed state, resulting in high performance and minimal overhead. The library combines a simple reactive primitive system with modern framework features like JSX, SSR, and Suspense.
Frontend developers building performant web applications who value a simple, reactive programming model without the complexity of virtual DOM diffing. It's suitable for projects ranging from SPAs to server-rendered applications.
Developers choose Solid for its exceptional performance, small bundle size, and straightforward mental model. Its fine-grained reactivity eliminates unnecessary rerenders, and its compile-time optimizations produce efficient real DOM updates, making it feel close to vanilla JavaScript while providing full framework capabilities.
A declarative, efficient, and flexible JavaScript library for building user interfaces.

Uses fine-grained reactivity to compile templates to real DOM nodes, achieving near-vanilla JavaScript speeds in benchmarks like the JS Framework Benchmark.
Core library is small and fully tree-shakable, resulting in fast load times and efficient resource usage, as highlighted in bundle size comparisons.
Components run once to set up the view, with reactivity handled through declarative primitives like signals, reducing complexity and improving debuggability.
Includes JSX, SSR, Suspense, and concurrent rendering out of the box, providing a comprehensive toolkit for both client and server environments.
Requires Babel or similar tooling for JSX compilation, adding setup overhead compared to frameworks that support plain JavaScript without build steps.
Smaller community and fewer third-party libraries than established frameworks like React, which can slow development when needing off-the-shelf solutions.
Fine-grained updates demand precise dependency tracking; mismanagement can lead to subtle bugs, such as stale closures or over-subscriptions.
