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.

Deep dive: Next.js

When to choose Next.js

Next.js is the right choice when you are building a React application that needs both server-side rendering and static generation under one roof, without stitching together separate tools. It fits teams that want the build toolchain, routing, data fetching, and deployment story to converge in a single framework with strong conventions. The App Router (introduced in v13, stabilized in v14) makes it the obvious pick when you need React Server Components, streaming, and Suspense boundaries at the routing level rather than as a library-level add-on. Teams deploying to Vercel get the best integration — ISR, Edge Middleware, and image optimization all work with zero configuration — but Next.js runs well on any Node.js host, including Railway, Render, Fly.io, and self-managed servers. It is the pragmatic choice for e-commerce storefronts, SaaS dashboards, marketing sites with heavy SEO requirements, and any product where a designer and a backend engineer need to work in the same codebase without a separate API layer. The ecosystem is the largest in the React meta-framework space: more Stack Overflow answers, more open-source starters, more third-party SDKs that ship Next.js examples by default. Choose Next.js over alternatives when team familiarity matters as much as raw performance, or when you need ISR to serve personalized content at CDN speed.

Real-world use case

A B2B SaaS company migrating from a Create React App frontend plus a separate Express API chose Next.js for a consolidation sprint. The team moved API routes into the Next.js route handlers, replaced client-side data fetching with React Server Components, and cut their Time to First Byte from 800ms to 120ms without a CDN change. The App Router's collocated loading.tsx and error.tsx files let them handle skeleton states and error boundaries at the route level rather than sprinkling them across every page component. The main friction point: the team had to unlearn the Pages Router conventions and relearn data fetching patterns from scratch. The learning curve cost approximately two weeks of slower velocity before productivity recovered.

Hidden gotchas

The App Router and Pages Router cannot share layout state — running both simultaneously during a migration creates two separate React trees with no shared context, which breaks global auth providers if you split pages across routers. Third-party libraries that wrap document.cookie or use useEffect on mount often break silently as Server Components because there is no window object and no lifecycle. The build output is not a pure static folder by default: even a mostly-static Next.js app generates a Node.js server that must stay running, which surprises teams expecting a deployable zip. The next/image component requires explicit allowlisting of external image domains in next.config.js; missing a domain causes silent 400 errors in production but works fine in development because dev mode is more permissive. Server Actions introduced in v14 write to the server-side module cache on first call — if you call a Server Action inside a loop without proper awaiting, you will encounter race conditions that only manifest under load and are extremely difficult to reproduce locally.

Pricing breakdown

Next.js itself is free and open-source under the MIT license. You pay only for hosting and infrastructure. Self-hosting on a $5/mo VPS (DigitalOcean, Hetzner) works for low-traffic sites. Vercel hosting (the company behind Next.js) starts free (100 GB bandwidth), with Pro at $20/user/mo. AWS Amplify charges $0.01/build-minute and $0.15/GB served. For a team of 3 on Vercel Pro, expect $60/mo plus $0.60 per 100K function invocations. The hidden cost: Next.js's tight Vercel integration means some features (ISR, Image Optimization, Edge Middleware) work better or only on Vercel, creating soft vendor lock-in.

Should You Use SolidStart or Next.js?

For most teams, SolidStart is the better default: it offers fastest js framework (benchmarks) and is open-source (from $0). Choose Next.js instead if most popular react framework matters more than very small ecosystem. There is no universal winner — the right pick depends on your budget, team size, and whether you value fastest js framework (benchmarks) or most popular react framework more.

Choose SolidStart if…

  • Fastest JS framework (benchmarks)
  • Fine-grained reactivity
  • React-like syntax

Choose Next.js if…

  • Most popular React framework
  • Best full-stack React experience
  • Excellent Vercel deployment
