Qwik
Qwik is a JavaScript framework that introduces resumability (no hydration) to deliver instant-loading applications even with complex interactivity. Its meta-framework, Qwik City, adds routing and SSR.

Deep dive: Qwik
When to choose Qwik
Qwik is the right framework when the project has strict Core Web Vitals requirements and the team wants near-instant page loads regardless of application complexity. Qwik achieves this through resumability: instead of hydrating the entire application on the client (like React, Vue, and Svelte do), Qwik serializes the application state into HTML and only downloads and executes JavaScript when the user interacts with a specific component. This means a complex e-commerce page with 50 components ships zero JavaScript until the user clicks a button, hovers a menu, or types in a search box. Qwik City, the meta-framework, adds file-based routing, data loaders, form actions, and middleware. Qwik is a weaker choice for teams that need a large component ecosystem, teams building offline-first PWAs (which need JavaScript upfront), or projects where the developer experience of a more mature framework like Next.js matters more than theoretical performance gains.
Real-world use case
A content publisher with 50,000 pages and a Time to Interactive requirement under 1 second evaluates Qwik against Next.js. The Next.js version ships 180 KB of hydration JavaScript on each page regardless of whether the user interacts with any component. The Qwik version ships 1.2 KB of the Qwik loader and defers everything else. When a user clicks the newsletter signup form, only the form component's JavaScript (4 KB) downloads. The publisher sees a 40% improvement in Interaction to Next Paint scores and a measurable improvement in ad viewability metrics. The tradeoff: the development team needs to learn Qwik's dollar-sign conventions ($, component$, useSignal, useTask$) which look foreign compared to React hooks, and the team cannot hire from the React talent pool without significant retraining.
Hidden gotchas
Qwik's lazy-loading boundary is the dollar sign ($). Every function passed to component$, useTask$, or event handlers like onClick$ becomes a separate lazy-loadable chunk. This is powerful but means closures that reference variables from the parent scope must be serializable. Non-serializable values like class instances, WeakMaps, or closures over DOM elements cause runtime errors that do not surface until the specific interaction triggers the lazy load. The error messages reference serialization constraints but do not always identify which variable caused the failure. Qwik's component testing story is less mature than React Testing Library. The official test utilities exist but community examples and patterns are sparse, so teams spend more time writing test infrastructure than they would with React or Vue. Third-party library compatibility is the biggest practical constraint: any library that assumes eager execution (runs code on import) breaks Qwik's resumability model. Libraries like date-fns work fine, but animation libraries that register global event listeners on import need wrapper components.
Pricing breakdown
Qwik is free and open-source under the MIT license. Qwik City (the meta-framework) is also free. Hosting: static sites deploy free on any CDN, SSR works on Cloudflare Workers ($0-5/mo), Deno Deploy, or Node.js hosts ($5-20/mo). There are no paid tiers. The unique cost advantage: Qwik's resumability eliminates hydration, meaning the server sends less JavaScript to the client — potentially reducing bandwidth costs by 40-70% compared to React/Next.js for highly interactive pages. The tradeoff: smaller ecosystem means more custom code for components other frameworks get from mature libraries.
Deep dive: SolidStart
When to choose SolidStart
SolidJS is the right pick when performance is the primary constraint and the team wants React-like JSX syntax without the virtual DOM overhead. Solid uses fine-grained reactivity: when a signal changes, only the specific DOM nodes that depend on it update, skipping the diffing step entirely. This makes it consistently faster than React in benchmarks and in production applications with frequent updates like dashboards, data grids, and real-time feeds. SolidStart, the meta-framework, adds file-based routing, SSR, and API routes. SolidJS is a weaker choice when the team needs a large ecosystem of pre-built components, when hiring from a broad talent pool matters (React dominates job listings), or when the project depends on React-specific libraries like React Three Fiber or Framer Motion that have no Solid equivalents.
Real-world use case
A fintech startup building a real-time trading dashboard chooses SolidJS because the UI updates 30+ data points per second from a WebSocket feed. With React, the team had measured re-render latency of 12-18ms per frame when multiple state atoms changed simultaneously. Switching to Solid's fine-grained reactivity dropped this to under 2ms because only the specific price cells and chart data points update, not the entire component tree. The team uses SolidStart for the SSR landing page and authentication flow, and a plain Solid SPA for the authenticated dashboard. The tradeoff: the team spent an extra week building a custom data table because there is no Solid equivalent of TanStack Table at feature parity, and Solid's createEffect has subtly different cleanup semantics than React's useEffect that caused two memory leak bugs during development.
Hidden gotchas
The most common mistake React developers make in Solid is destructuring props. In React, const { name } = props works because props are plain objects. In Solid, props are reactive proxies, and destructuring breaks reactivity — the destructured value captures the initial value and never updates. The fix is to always access props.name or use splitProps, but this trips up every React developer on their first Solid project. Solid's JSX looks identical to React's but compiles to direct DOM operations, not createElement calls. This means React DevTools does not work, and the Solid DevTools browser extension is less mature. SolidStart is still evolving rapidly and has gone through multiple router implementations. Projects started on SolidStart 0.3 require meaningful migration work to reach 1.0, and some API routes patterns changed entirely between beta releases.
Pricing breakdown
SolidJS is free and open-source under the MIT license. SolidStart (the meta-framework) is also free. Hosting costs mirror other frameworks: static sites deploy free on any CDN, SSR requires a Node.js runtime ($5-20/mo). There are no commercial products, enterprise tiers, or paid features. The total cost for most projects is $0-10/mo for hosting. The performance advantage translates to cost savings at scale: SolidJS's fine-grained reactivity produces smaller bundles and fewer re-renders, reducing server compute and bandwidth costs by 20-40% compared to React for interactive applications.
Should You Use Qwik or SolidStart?
For most teams, Qwik is the better default: it offers fastest time to interactive and is open-source (from $0). Choose SolidStart instead if fastest js framework (benchmarks) matters more than very small community. There is no universal winner — the right pick depends on your budget, team size, and whether you value fastest time to interactive or fastest js framework (benchmarks) more.
Choose Qwik if…
- •Fastest time to interactive
- •No hydration overhead
- •React-like syntax
Choose SolidStart if…
- •Fastest JS framework (benchmarks)
- •Fine-grained reactivity
- •React-like syntax
