Frequently asked questions
Do you build with Next.js or TanStack Start?
Both. We default to Next.js for content-heavy and SEO-critical apps and TanStack Start for SaaS where end-to-end type-safe routing and server functions are valuable.
Can you work alongside our existing React team?
Yes — we routinely embed as a senior React pod, contributing via your PR workflow, design system and review standards.
Do you also do React Native?
Yes. We share React 19 + TypeScript + state management across web and mobile so your team isn't maintaining two divergent stacks.
Will my React app be SEO-friendly?
We build with SSR/SSG by default (Next.js or TanStack Start), ship pre-rendered metadata, JSON-LD structured data and pass Core Web Vitals before launch.
Can you migrate us off Create React App?
Yes — incremental migrations from CRA to Vite, Next.js or TanStack Start are one of our most-requested engagements.
