What Generic React Agencies Say:
What Protocloud Delivers:
Often optional or loose 
TypeScript strict - mandatory on every project 
ReactJS development starts from $5,000 for a React SPA with TypeScript, testing, and component documentation. Mid-complexity React dashboards: $10,000–$30,000. Full Next.js SaaS platforms: $20,000–$80,000. React component library (design system): $8,000–$20,000. Legacy jQuery or Angular migration to React: from $6,000, scoped after code audit. AI React feature additions: from $3,000 per feature. All projects receive a fixed quote before any work begins.
React SPA is the right choice for complex authenticated applications where SEO is not a priority – SaaS dashboards, admin panels, internal tools, and data-heavy applications where all content is behind a login. Next.js is the right choice for any application with public-facing pages that need to rank on Google – marketing sites, SaaS landing pages, eCommerce, and public-facing product pages. In 2026, we recommend Next.js 14 (App Router) for 70% of new React projects because the SEO and performance benefits are significant even for primarily-SaaS products that also have a marketing website. We make this recommendation during your free strategy session with a written rationale.
State management is the most consequential architectural decision in a React application. We use a “right tool for each state type” approach: TanStack Query (React Query) for server state – data that comes from your API, with built-in caching, background refetching, and optimistic updates; Zustand or Jotai for lightweight global UI state – cleaner than Redux for most use cases; Redux Toolkit for complex, interdependent global state in large enterprise applications; and local useState/useReducer for component-isolated state. This approach prevents “state spaghetti” and ensures predictable, debuggable data flow throughout your application.
Yes – we integrate OpenAI GPT-4o streaming, LangChain.js RAG pipelines, TensorFlow.js browser inference, and custom AI component libraries into existing React and Next.js applications. We build AI features as isolated, documented React components – so they can be tested, maintained, and extended independently from your core application. Whether AI is the right investment for your specific use case is a separate question – and we give you an honest ROI-based answer before recommending any AI feature. AI React features start from $3,000.
Simple React SPA: 4–6 weeks. Next.js marketing + SaaS platform: 8–12 weeks. Complex SaaS dashboard with real-time features: 10–16 weeks. React component library: 6–10 weeks. Legacy migration (Angular/jQuery to React): 8–16 weeks depending on codebase size. We deliver weekly Vercel preview links throughout development so you see real progress – never a 10-week silence followed by a big reveal.
Four written guarantees: (1) Lighthouse 90+ score – we continue optimising at no charge until this is verified; (2) Fixed price – your quote is the final invoice, no scope creep surprises; (3) Fixed timeline – delays on our side result in additional free development; (4) 3 months post-launch support – bug fixes, security patches, and dependency updates at zero cost. TypeScript strict mode, Jest 90%+ coverage, and Storybook documentation are non-negotiable delivery conditions – not optional extras.
React is a UI library – it handles the view layer only. Next.js is a full-stack React framework adding server-side rendering (SSR), static generation (SSG), incremental static regeneration (ISR), API routes, and optimised image serving. For most new projects in 2026, Next.js 14 is our default recommendation because it delivers React’s component model with built-in SEO capability, faster initial page loads, and edge deployment. React SPA (without Next.js) is the right choice for complex authenticated dashboards where SEO is not a requirement – like admin panels and internal tools. We make this recommendation during your free strategy session based on your specific use case.
🛡 Guarantee: We document our framework recommendation in writing – with the rationale – before any development begins. If our recommendation changes based on new information, we explain why transparently.
Technical debt in React is primarily caused by three things: no TypeScript (type errors caught at runtime instead of compile time), no test coverage (no safety net for refactoring), and no state management architecture (uncontrolled prop drilling and side effects). We address all three by default – TypeScript strict mode, Jest 90%+ coverage, and documented state management architecture. We also provide a 30-minute architecture walkthrough video as part of every handover so your team understands every system decision.
🛡 Guarantee: We deliver a written architecture decision record (ADR) documenting every significant technical decision made during the project – so future developers understand why choices were made, not just what was built.
Performance is a delivery requirement, not a feature. Before any deployment, every Protocloud React application must pass: React DevTools Profiler audit (zero unnecessary re-renders on critical paths), Lighthouse 90+ on all major routes, First Contentful Paint under 1.5s on mobile, and Cumulative Layout Shift below 0.1. These benchmarks are in your Statement of Work and must be met before final invoice.
🛡 Guarantee: Specific Lighthouse and Core Web Vitals benchmarks are written into your delivery specification. Final payment is only due after performance benchmarks are verified and passed.
Maintainability is built into our delivery process – not added as an afterthought. We deliver: TypeScript-typed codebase (any TypeScript developer can read it), Storybook component documentation (every component has usage examples and props documentation), Jest test suite (developers can refactor confidently knowing tests catch regressions), architecture README (system overview, folder structure rationale, state management patterns, API layer documentation), and a 60-minute developer handover call.
🛡 Guarantee: We include a 90-day codebase adoption guarantee – if your development team struggles to extend the codebase within 90 days of handover due to insufficient documentation or architectural confusion, we provide additional documentation and consultation at zero cost.
Our component architecture and TypeScript foundation is specifically designed for extensibility. New features that build on the existing component library, state management patterns, and API layer can be added in days rather than weeks – because the foundation is clean and documented. Post-launch feature additions are scoped and priced transparently, delivered in the same sprint cadence as the original project, and always shipped with the same TypeScript, test, and Storybook standards as the original codebase.
🛡 Guarantee: New features are always delivered at the same architecture and quality standard as the original project – TypeScript, Jest coverage, and Storybook documentation included. No cutting corners on v2 features.
