Best SolidJS and SolidStart Boilerplates in 2026

TL;DR

SolidJS is the most technically impressive JavaScript UI framework available in 2026 — its fine-grained reactivity system is more efficient than React's virtual DOM by every meaningful benchmark. But "most technically impressive" doesn't mean "right for your SaaS boilerplate." The SolidStart ecosystem is genuinely useful for performance-critical dashboards, data-heavy admin panels, and real-time apps where React's re-rendering overhead shows up in profiling. The starter ecosystem is smaller than Next.js (by a lot), but the official SolidStart v1 framework is now production-ready, and community starters have matured. If you're willing to build on a smaller ecosystem for real performance gains, SolidJS is a legitimate choice in 2026.

Key Takeaways

SolidJS renders faster than React for component-heavy UIs — benchmarks consistently show 2-4x better performance for large lists and high-frequency updates
SolidStart v1.0 shipped in 2024 and is now stable — file-based routing, SSR, server functions, middleware — a complete Next.js-style meta-framework
The ecosystem is ~5% of React's — far fewer third-party component libraries, less community support, fewer StackOverflow answers
Solid-Start SaaS Starter (community) is the best production-ready starting point — auth, Stripe, database, email all pre-integrated
Fine-grained reactivity means no unnecessary re-renders — createSignal updates only the exact DOM nodes that depend on the signal, not the entire component tree
JSX that looks like React but works differently — Solid uses JSX but doesn't diff virtual DOM; it compiles to direct DOM operations

Why SolidJS Is Worth Considering in 2026

React's re-rendering model works as follows: when state changes, React re-runs the component function and diffs the output. For most apps this is fast enough. But for real-time dashboards updating 100+ data points per second, charts rendering thousands of data series, or admin grids with complex conditional formatting, the React re-render overhead becomes visible.

SolidJS avoids this entirely with fine-grained reactivity:

// React: every state change re-runs the entire component
function Counter() {
  const [count, setCount] = useState(0)
  // When setCount runs, React re-executes this function
  // and diffs the previous/new virtual DOM
  return <button onClick={() => setCount(c => c + 1)}>{count}</button>
}

// SolidJS: only the text node updates — no function re-execution
function Counter() {
  const [count, setCount] = createSignal(0)
  // When setCount runs, ONLY the DOM text node containing count() updates
  // The function body never re-runs
  return <button onClick={() => setCount(c => c + 1)}>{count()}</button>
}

The SolidJS component function runs once on mount. After that, only the reactive primitives (createSignal, createMemo, createEffect) re-evaluate when their dependencies change — and only the specific DOM nodes that depend on them update.

For most CRUD SaaS apps, this optimization is academic — you'll never notice the difference. For real-time trading dashboards, collaborative editors, or live analytics pages, this is the difference between 60fps and janky.

SolidStart v1: The Framework

SolidStart is Solid's meta-framework — equivalent to Next.js or SvelteKit. As of v1.0:

File-based routing — src/routes/users/[id].tsx maps to /users/:id
Server functions — "use server" directive works like Next.js Server Actions
SSR/SSG/SPA modes — configurable per-route
API routes — src/routes/api/users.ts for server endpoints
Middleware — src/middleware.ts for auth, logging, rate limiting
Adapters — Vercel, Netlify, Cloudflare Workers, Node.js, AWS Lambda

// src/routes/dashboard.tsx
import { createAsync, cache } from '@solidjs/router'
import { Show, Suspense } from 'solid-js'
import { getSession } from '~/server/auth'

// Server-side data fetching (runs on server)
const getUser = cache(async () => {
  'use server'
  const session = await getSession()
  if (!session) throw redirect('/login')
  return db.users.findById(session.userId)
}, 'user')

export const route = { preload: () => getUser() }

export default function Dashboard() {
  const user = createAsync(() => getUser())

  return (
    <Suspense fallback={<div>Loading...</div>}>
      <Show when={user()} keyed>
        {(u) => <h1>Welcome, {u.name}</h1>}
      </Show>
    </Suspense>
  )
}

The Best SolidStart Boilerplates

1. Solid SaaS Starter (Community)

The most complete SaaS starter for SolidStart, maintained by the community:

GitHub: solidjs-community/solid-saas-starter

Includes:

SolidStart v1 with TypeScript
Drizzle ORM + PostgreSQL (Neon or local)
Auth with @solid-auth (credentials + OAuth)
Stripe subscriptions + webhooks
Resend for transactional email
shadcn-solid UI components
Tailwind CSS 4

This is the closest equivalent to T3 Stack or ShipFast in the Solid ecosystem. It's not as polished as its React counterparts but covers all the production essentials.

Setup:

git clone https://github.com/solidjs-community/solid-saas-starter
cd solid-saas-starter
cp .env.example .env
npm install
npm run db:push
npm run dev

2. create-jd-app (SolidJS + tRPC)

For teams familiar with T3 Stack's pattern but wanting SolidJS performance, create-jd-app provides a similar stack:

npx create-jd-app@latest my-app

Stack: SolidStart + tRPC + Prisma + Tailwind + Lucia Auth

The tRPC integration for SolidJS uses @solid-mediakit/trpc and provides the same end-to-end type safety as T3 Stack.

3. SolidStart Minimal Starter (Official)

For teams that prefer building up from minimal:

npx degit solidjs/solid-start/examples/bare my-app

The official bare starter gives you SolidStart with routing and TypeScript, nothing else. Good starting point if you want to compose your own stack.

4. Solid + Vinxi + Cloudflare Workers

For edge-first deployments, SolidStart's Cloudflare adapter is production-ready:

npx create-solid@latest --template with-cloudflare-workers

SolidJS's small runtime (~7kB) makes it an excellent fit for Cloudflare Workers where cold start size matters. A full SolidStart app deploys to Cloudflare Workers with V8 isolates, meaning sub-10ms cold starts.

SolidJS vs. React: When to Use Each

React Wins When:

Your team already knows React — retraining cost is real
You need a specific React library with no Solid equivalent (complex data visualization, specialized UI components)
You're building a standard CRUD SaaS with moderate data volumes
You need the most answers on StackOverflow when debugging
You're hiring and React is significantly more common in your candidate pool

SolidJS Wins When:

Real-time updates: live trading data, collaborative editing, live sports scores
Large data tables: virtual scrolling of 10,000+ rows without React's memo complexity
Animation-heavy UIs: game UIs, data visualizations, interactive simulations
Edge deployments: SolidJS's ~7kB runtime vs React's ~45kB matters at the edge
Learning purposes: understanding fine-grained reactivity makes you a better React developer too

Solid Component Patterns for SaaS

Reactive Data with createResource

SolidJS's createResource is the built-in data fetching primitive — no React Query needed:

import { createResource, Show, Suspense, ErrorBoundary } from 'solid-js'

function UserProfile({ userId }: { userId: string }) {
  const [user, { refetch }] = createResource(
    () => userId,  // Source signal — refetches when userId changes
    async (id) => {
      const res = await fetch(`/api/users/${id}`)
      if (!res.ok) throw new Error('User not found')
      return res.json()
    }
  )

  return (
    <ErrorBoundary fallback={(err) => <div>Error: {err.message}</div>}>
      <Suspense fallback={<div>Loading profile...</div>}>
        <Show when={user()} keyed>
          {(profile) => (
            <div>
              <h2>{profile.name}</h2>
              <button onClick={refetch}>Refresh</button>
            </div>
          )}
        </Show>
      </Suspense>
    </ErrorBoundary>
  )
}

Stores for Complex State

For multi-property state (like form state or global app state), createStore provides fine-grained property-level reactivity:

import { createStore, produce } from 'solid-js/store'

interface AppState {
  user: { id: string; name: string; plan: string } | null
  notifications: { id: string; message: string; read: boolean }[]
}

const [state, setState] = createStore<AppState>({
  user: null,
  notifications: [],
})

// Fine-grained update — only the specific `read` property of notification[2] updates
function markNotificationRead(id: string) {
  setState(
    'notifications',
    (n) => n.id === id,
    produce((n) => { n.read = true })
  )
}

The SolidJS Ecosystem in 2026

The SolidJS ecosystem is smaller than React's but more complete than it was two years ago. Here's what's available:

UI Component Libraries for SolidJS

Library	Description	React Equivalent
shadcn-solid	Radix-UI + Tailwind ports for Solid	shadcn/ui
Solid UI	Official component primitives	Headless UI
SUID	Material UI port for Solid	MUI
Hope UI	Full component library with theming	Chakra UI
Kobalte	Accessible headless components	Radix UI

shadcn-solid is the community-maintained port of shadcn/ui's component patterns for SolidJS. If your team already knows shadcn/ui's approach, the transition is low-friction.

State Management

SolidJS's built-in primitives cover most state management needs:

createSignal — single-value reactive state (replaces useState)
createStore — nested object state with fine-grained updates (replaces Redux for most cases)
createContext — shared state without prop drilling (replaces React Context)

For complex global state, the community uses:

Solid-zustand — Zustand port for SolidJS
@tanstack/solid-query — TanStack Query for Solid (official support)
SolidJS/contexts — context utilities

Data Fetching

@tanstack/solid-query — TanStack Query works natively with Solid
createResource — built-in, covers async data with loading/error states
SolidStart server functions — for server-side data fetching with "use server"

Forms

@tanstack/solid-form — TanStack Form for Solid (official support)
Modular Forms — lightweight form library built specifically for Solid

SolidStart Deployment Options

SolidStart's adapter system supports all major deployment targets:

// vite.config.ts — switch adapter based on target
import { defineConfig } from '@solidjs/start/config'

export default defineConfig({
  server: {
    // Vercel: just works with zero config
    // preset: 'vercel'

    // Cloudflare Workers
    preset: 'cloudflare-pages',

    // Node.js (Railway, Fly.io, self-hosted)
    // preset: 'node'

    // AWS Lambda
    // preset: 'aws-lambda'
  },
})

Vercel deployment is zero-config — push to GitHub, connect to Vercel, done. SolidStart outputs to the Vercel edge runtime automatically.

Cloudflare Pages deployment is excellent for SolidJS — the small runtime (~7kB vs React's ~45kB) means workers deploy faster and have better cold starts.

Railway / Fly.io work with the Node.js preset — npm run build outputs a Node.js server.

Migration Path: React → SolidJS

If you're considering migrating an existing React app to SolidJS:

Don't migrate the whole app — start with a new SolidJS island in an existing page
Components look similar but hooks are very different (useState → createSignal, useEffect → createEffect, useMemo → createMemo)
No re-render model requires mindset shift — you can't rely on "re-renders will pick up the latest value"; everything must be reactive
Conditional rendering is explicit — use <Show> and <For> components instead of ternaries and .map() (ternaries work but create/destroy DOM nodes on every evaluation)
