SolidJS vs React (2026)

React remains the de facto frontend standard, but over the past couple of years SolidJS has built a solid reputation as "the framework that got reactivity right." Solid has no virtual DOM, a component runs exactly once, and updates land with surgical precision. That sounds like marketing copy, but it's a direct consequence of the architecture. Let's dig into where SolidJS is genuinely ahead of React on a technical level, what the current 2025-2026 benchmarks and surveys actually say, and — without sugarcoating it — where React still wins by a wide margin.

Reactivity: signals vs the virtual DOM

The core architectural difference sits at the heart of rendering. In React, a component is a function that re-executes in full whenever state changes; the result is diffed against the previous tree via the virtual DOM, and only then are targeted patches applied to the real DOM. It's a convenient model, but it charges a computational tax on every update, even when a single text field deep inside a nested tree is all that changed.

SolidJS works fundamentally differently: JSX compiles down to plain DOM node creation calls, and state lives in signals (createSignal) that the component reads once, during the first render. After that, the component function's body never runs again — instead, fine-grained reactive subscriptions are wired up directly: a specific DOM node subscribes straight to a specific signal and updates without any tree comparison whatsoever. Developers call this fine-grained reactivity, as opposed to React's "coarse-grained" component re-rendering. One commenter on the Solid 2.0 beta puts it bluntly: Solid has always had the best reactivity model among JS frameworks — true fine-grained updates without a virtual DOM. That's a bold claim, but it's backed by a concrete architecture that skips the diffing pass entirely, not just the author's personal enthusiasm.

Signals have long stopped being one framework's party trick — even competitors have adopted the idea. Angular officially acknowledged that its own signal-based reactivity model (signal(), computed(), effect()) was partly inspired by SolidJS: in the Angular Signals RFC, the Angular team directly credits Solid's creator, Ryan Carniato, for the insight and consultation he provided during the design process. When a framework the size of Angular — one that's been tied to Zone.js and its own change-detection model for a decade — pivots toward Solid's ideas, that says more than any marketing ever could.

The practical upshot: in React, developers have to manually shield components from unnecessary re-renders, or lean on the React Compiler to do it for them. In Solid, unnecessary re-renders structurally don't exist in the first place — only the DOM node that actually depends on the changed signal gets updated.

What the benchmarks say about performance

The architectural gap shows up directly in synthetic tests. Stefan Krause's js-framework-benchmark — the most frequently cited independent frontend framework benchmark — has shown the same pattern for years: SolidJS consistently sits in the top tier of results, right next to "pure" VanillaJS with no framework at all, while React noticeably lags in scenarios with frequent fine-grained updates, large lists, and deeply nested component trees. The current state-of-Solid.js-in-2026 overview, which draws on that benchmark's data, confirms this. According to Boundev's analysis, in scenarios typical of js-framework-benchmark — creating, updating, and deleting thousands of rows — SolidJS beats React on runtime performance by roughly 50-70%. Worth flagging right away: that's not a universal constant that applies "to any website," it's the result of synthetic, update-heavy tests where the gap between fine-grained reactivity and the virtual DOM is at its most visible.

On real production interfaces the picture is more modest: most of the time budget there goes to network requests, images, and third-party JS rather than DOM diffing, so the gap tends to be much smaller than in the lab. The React Compiler (more on that below) narrows it further still.

Bundle size

Fine-grained reactivity gives SolidJS another side benefit: Solid's compiler turns JSX into direct DOM instructions without needing to ship a virtual-DOM diffing engine at runtime, so the framework itself ends up noticeably lighter. According to the state-of-Solid.js-in-2026 overview, Solid's core weighs around 7.6 KB minified and gzipped, versus roughly 45 KB for React + ReactDOM combined, 38 KB for Vue, and 85+ KB for Angular. The same source, citing a case study from Radware, gives a real production example: for a feature-comparable application, the SolidJS bundle came in around 80 KB versus roughly 290 KB for React. The independent framework-benchmarks.as93.net project paints a similar picture — it builds an identical app across different frameworks specifically to compare bundle sizes fairly, and there the gzipped size of a typical weather app built with Solid came out to about 9 KB.

For projects where fast first load on slow networks and weak devices actually matters, these kilobytes translate directly into milliseconds of Time to Interactive rather than staying a nice number in a report.

React Compiler: React strikes back

It would be unfair to describe React the way it looked in 2023. On October 7, 2025, the React team announced the release of React Compiler 1.0 — a build-time compiler that automatically inserts memoization across the component tree, taking over work that used to be done manually with useMemo, useCallback, and React.memo. According to that same official announcement, on real products like the Meta Quest Store the compiler delivered up to a 12% improvement on initial load and cross-page navigation, and sped up individual interactions by more than 2.5x — with neutral memory consumption. By 2026, the React Compiler is considered default practice for new React projects, and its rules are baked directly into the recommended eslint-plugin-react-hooks preset.

This doesn't erase the fundamental architectural difference — the React Compiler still operates on top of the "re-execute the whole component, but avoid redundant work through memoization" model rather than fine-grained signals. But it meaningfully narrows the practical gap in production, and it takes a big chunk of manual optimization off the developer's plate — optimization that used to be a common source of bugs from forgotten dependencies in useMemo/useCallback arrays.

Developer experience: signals are pleasant, but not without surprises

Solid's syntax is deliberately React-like — JSX, hook-like primitives (createSignal, createEffect, createMemo), a component-based approach — so the transition for a React developer feels a lot softer than, say, switching to Vue with its templates and SFCs. But a model without component re-rendering brings its own set of gotchas you won't find in React.

The main source of beginner mistakes is prop destructuring. In React, const { name } = props is standard practice. In Solid, props are implemented via getters specifically to enable fine-grained reactivity, so destructuring props "at the door" of a component breaks the reactive link and freezes the value at the moment of the first call. A rundown of SolidJS's practical pitfalls lists several other non-obvious traps: calling an arbitrary function inside createEffect implicitly subscribes the effect to every signal that function reads (which sometimes calls for wrapping it in untrack), directives are awkward to reuse across files because of how the TypeScript compiler handles them, and resource primitives don't support partial updates of nested fields — changing a single object property recreates the whole thing and triggers dependent effects unnecessarily. Nothing fatal, but it takes time to get used to, and none of it is particularly intuitive if your background is purely React.

On the plus side, there are noticeably fewer React-specific constraints to worry about: you don't need to remember the "rules of hooks" (no conditional or looped hook calls), because Solid's primitives aren't tied to call order inside a render, and a component that runs only once eliminates an entire class of stale-closure bugs that plague useEffect.

TypeScript deserves its own mention, and here Solid has a genuinely objective structural edge. Solid is written in TypeScript from the ground up, and types for all its primitives (createSignal, createEffect, createMemo, JSX components) ship directly inside the solid-js package — I checked its package.json directly via the npm registry, and it has a "types": "types/index.d.ts" field pointing to bundled declarations; there's simply no separate @types/solid-js package in the registry. React's situation is different: its own package.json has no types field at all — typings live in a separate @types/react package, which React.dev itself describes as sourced from DefinitelyTyped, meaning it's community-maintained rather than maintained by the React team directly. In practice, that means React's types can temporarily fall out of sync with the runtime when new versions ship (a common example being delays in typing new hooks), whereas for Solid, types and runtime are always the same version by construction, because they're literally the same package.

Ecosystem and market: where React wins decisively

In terms of ecosystem reach and maturity, React is still in a league of its own — there isn't much to argue about here, the gap in its favor is measured in orders of magnitude.

Developer surveys. According to State of JavaScript 2025, React remains the most-used frontend framework: 83.6% of respondents use it at work, compared to about 10% for SolidJS. At the same time, Solid has held the highest satisfaction rating among frameworks for five years running — people who've tried it rarely want to go back to alternatives, but the overwhelming majority of the market is still on React. That popularity has a flip side: the same survey records complaints about React's complexity and about the monetization strategy around Next.js/Vercel — one of the most frequently mentioned pain points in respondent comments. The numbers back this up: Next.js satisfaction in the survey dropped from 68% to 55% amid growing complexity around Server Components and the App Router, and React itself, despite 98% usage reach, draws the most specific complaints about individual APIs — useEffect got the lowest satisfaction rating of any hook, with dependency-array issues coming in second (21% dissatisfied). React's popularity isn't going anywhere, it remains dominant — but satisfaction with working on it, and with its flagship meta-framework, has dropped noticeably.

GitHub. The gap in community size is also visible in the repositories: facebook/react has around 247,000 stars versus roughly 35,700 for solidjs/solid — nearly a sevenfold difference, reflecting the scale of the contributor base and outside attention.

Job market. The gap in job listings is even starker than the one in GitHub stars: React has effectively become a baseline requirement in frontend job postings at large companies, while the SolidJS developer community remains niche — there are an order of magnitude fewer openings, and hiring mostly happens through niche boards like SolidJS Jobs Listing rather than mainstream job boards.

Ready-made solutions. React has Next.js, Remix/React Router, React Native for mobile, dozens of mature UI kit libraries, and years' worth of ready-made answers on Stack Overflow — things that in Solid often need to be solved yourself or wait for the ecosystem to catch up. SolidStart, the Next.js-equivalent meta-framework for Solid, is still under active development: as of early 2026 it's at SolidStart 2.0.0-alpha.2, while the Next.js ecosystem has years of production usage under its belt at companies like Vercel, Nike, TikTok, and dozens of others. For teams that care about predictable hiring, API stability, and a wide range of ready-made integrations, this is a heavy — and often decisive — argument in favor of React, regardless of the competitor's architectural advantages.

Native apps deserve a separate note: React has React Native, while Solid has no direct framework equivalent for mobile development. It does have an alternative on a different stack that covers more than just desktop, though. SolidJS pairs well with Tauri — a Rust wrapper that renders a frontend built with any web framework, but instead of bundling Chromium like Electron does, it uses the system's WebView, resulting in dramatically smaller binaries and lower memory usage. With the stable release of Tauri 2.0, the framework stopped being a purely desktop tool: it now officially supports iOS and Android from the same codebase — WKWebView on iOS, the system Android WebView on Android — meaning that, in theory, a single Solid app can be built for all five platforms at once (Windows, macOS, Linux, iOS, Android). The mobile side is younger than the desktop side and still a bit rough around the edges — there are quirks around plugins, app signing, and webview peculiarities — but it's already usable in production, not just a proof of concept. There are official and community-maintained Tauri + Solid starter templates (riipandi/tauri-start-solid, ZanzyTHEbar/SolidJSTauri, and for mobile builds specifically SolidJSTauriMobile), and a walkthrough of the Rust + SolidJS + Tauri combo for cross-platform apps has also been published on LogRocket Blog. Electron is still unmatched in desktop maturity and reach for now — roughly 4.95 million weekly downloads for electron from npm versus about 1.96 million for @tauri-apps/cli (npm registry data for July 13-19, 2026) — and it's still slightly ahead on GitHub stars too (122K versus 109K for tauri-apps/tauri). But the gap is noticeably narrower than on the web, and the fact that Tauri has grown from a niche desktop project into a full-fledged cross-platform alternative to both Electron and React Native within a couple of years makes Solid + Tauri a genuinely fast-growing choice in exactly the area where SolidJS used to have a structural gap versus React.

SolidJS 2.0 and SolidStart: where the framework is headed

The project isn't standing still. The SolidJS 2.0 beta shipped on May 15, 2026 — the first major release to make async a first-class citizen directly inside the reactive graph: computations can now return promises directly, and the framework handles suspending and resuming on its own, without wrapping everything in Suspense. The release also drops the old Suspense in favor of a simpler Loading that's only responsible for a subtree's initial readiness, adds action() and createOptimisticStore for mutations, and now batches signal writes at the microtask level — a refactor that the framework's creator, Ryan Carniato, defends as the outcome of more than a year spent analyzing alternative approaches, even though part of the community finds the new split-phase createEffect API clunkier at first glance.

The current stable line is 1.9.x (according to the state-of-Solid.js-in-2026 overview, the latest version is 1.9.11), so the 2.0 beta isn't yet recommended for new production projects. But the very fact that the framework keeps getting architectural investment, rather than freezing on a "stable but neglected" 1.x, is a good sign for its continued viability.

Bottom line: when to pick what

Technically, SolidJS really is better than React in a lot of ways: fine-grained reactivity without a virtual DOM eliminates an entire class of re-render problems, synthetic benchmarks like js-framework-benchmark consistently put Solid on par with vanilla JS, and the bundle ends up several times lighter for comparable functionality. All of that is a direct consequence of compiling JSX into fine-grained DOM operations, not empty fan enthusiasm.

But "technically better" and "the right choice for your team right now" are different questions. The React Compiler has meaningfully narrowed the practical performance gap in production, and React's ecosystem, job market, and sheer volume of ready-made solutions remain an order of magnitude bigger than Solid's. That directly affects development speed and how easy it is to hire for the project — a factor that matters for years, not one sprint. If you're starting a personal or small commercial project where performance and a small bundle really matter, and flexibility in picking libraries isn't a priority — SolidJS is a mature, well-justified choice today. If you're working on a large team, depend on a wide range of ready-made integrations, need React Native, or simply don't want to spend weeks hunting for a rare specialist later — React remains the far safer bet, and the React Compiler only strengthens that bet.
