Single Page Application Development
With Sub-Second Loads.
React, Vue, or Angular SPAs that feel like native apps. Instant navigation, optimistic UI, offline-ready. 98+ Lighthouse scores by default.
React, Vue, or Angular?
React
Most popular, largest ecosystem
Vue 3
Gentle learning curve, clean API
Angular
Enterprise, opinionated, full-featured
“Our old multi-page dashboard took 4 seconds to navigate. The new React SPA loads in under 1 second and navigates instantly. User engagement tripled.”
Single-page apps built for speed + scale.
SPAs are the default for modern web apps — but done poorly, they're slow, SEO-hostile, and fragile. We build SPAs with hybrid rendering, aggressive code-splitting, and proper SEO.
Architecture + tooling
Week 1-2Framework choice (Next.js / Remix / Astro + React islands), state management (Zustand / Jotai / TanStack Query), data-fetching strategy, SSG + SSR + CSR boundaries.
Build + performance
Week 3-6Route-based code splitting, image optimization (AVIF + WebP), prefetching strategy, suspense + streaming, React Server Components where applicable.
SEO + accessibility
Week 7Schema.org, canonical URLs, server-side rendering for SEO-critical routes, semantic HTML, WCAG 2.2 AA compliance, sitemap + robots.txt, search-console monitoring.
Launch + observability
Week 8+Real-user monitoring (RUM), Core Web Vitals dashboards, error tracking (Sentry), performance budget CI gates, ongoing performance tuning.
SPAs without the usual SPA tradeoffs.
Fast, SEO-friendly, accessible SPAs — the version that actually works for real businesses.
Framework + architecture
Next.js, Remix, or Astro depending on needs. Opinionated defaults: route-based code splitting, React Server Components where applicable, hybrid SSR + SSG + CSR.
Performance-first build
Core Web Vitals as release gate. LCP < 1.8s mobile, CLS < 0.1, INP < 200ms. AVIF images, preload critical fonts, route prefetching, edge caching.
SEO + schema
Server-side rendering for SEO-critical routes, schema.org JSON-LD, OG + Twitter cards, canonical URLs, sitemap automation, Search Console verified from day 1.
Accessibility + testing
WCAG 2.2 AA baseline, axe-core CI checks, keyboard-navigation audits, screen-reader testing, Playwright E2E suite, visual regression via Percy or Chromatic.
Built for product-led web apps + dashboards.
SPAs shine for complex, stateful, interactive apps — dashboards, editors, collaborative tools. Marketing sites typically don't need them.
Dashboards + Analytics
Complex data visualization, real-time charts, interactive filtering. SPA responsiveness is the user experience — multi-page navigation would feel archaic.
Editors + Canvas Tools
Design tools, document editors, project boards, whiteboards. Stateful UIs with collaborative editing + undo/redo need SPA architecture.
B2B SaaS Applications
Admin consoles, workflow tools, CRMs, dashboards. SPA UX is the default standard for modern B2B — static sites feel like 2010.
Interactive Consumer Apps
Social networks, games, messaging apps, interactive configurators. Native-app-like UX in the browser requires SPA foundations.
Production-grade tooling, included.
Enterprise-grade engineering stack bundled in — no client pays separately for the tools we use every day.
SPAs, answered honestly.
React vs. Vue vs. Svelte?
React for the largest ecosystem + hiring pool. Vue for teams that prefer its DX + simpler mental model. Svelte for new projects prioritizing performance + bundle size. 85% of our work is React-based; we'll ship whichever makes your team productive.
Is SEO really possible with SPAs?
Yes — with server-side rendering or static generation. Next.js, Remix, and Astro all solve this. Google renders JavaScript (eventually), but SSR/SSG is still 2-3× faster to index + ranks better for competitive terms.
Will my SPA be accessible?
Yes — we ship WCAG 2.2 AA compliant by default. Focus management on route changes, semantic HTML, ARIA attributes, keyboard traps handled. Accessibility isn't a SPA limitation when done deliberately.
Can you migrate our existing SPA?
Yes. Typical migrations: legacy React (class components) → modern React + Next.js. Angular → React / Remix. Vue 2 → Vue 3. Incremental migrations using route-by-route replacement strategies.
What about Core Web Vitals?
Every SPA we ship passes all three Core Web Vitals as a release gate. We enforce CWV budgets in CI — a PR that regresses LCP > 1.8s or INP > 200ms physically cannot merge.
