Why IRPR is the best React frontend development agency
We deliver React frontends that load fast, scale without rewrites, and ship on time.
Our team has shipped 200+ frontend products for clients in 50 countries. Every project uses Next.js, TypeScript, and Tailwind CSS with real testing coverage. We write unit tests with Jest, integration tests with Cypress, and performance audits with Lighthouse.
Clients see 40% faster time-to-market compared to hiring in-house. Our fixed-price model means you know the cost day one. We handle everything from design to deployment on Vercel or AWS.
How we differ from other React agencies
Most agencies bill hourly and leave you with unclear scope and slow progress. IRPR is different.
We build an interactive prototype in the Roadmap phase (week 2) that works on real data. You see exactly what you will get before we write production code. Changes after Roadmap cost nothing if they stay within the defined scope.
Our engineers average 10+ years of React experience. Every project includes a dedicated tech lead, a QA engineer, and a project manager. We do not outsource or use offshore rates that hide communication delays.
- Hourly billing with no cap
- Junior developers learning on your dime
- No design support included
- Slow weekly status calls with no demo
- Code with no tests or documentation
- No deployment or CI/CD setup
- Fixed price for the entire frontend
- Senior engineers with 10+ years experience
- In-house UI/UX design included
- Bi-weekly working demos with live feedback
- 100% test coverage on core flows
- CI/CD pipeline on GitHub Actions + Vercel
Our React frontend development process
We follow a proven 4-phase approach that eliminates guesswork.
Phase 1: Ideation. We map your user flows, wireframes, and API contracts in 1 week. You get a clear spec document before any code is written.
Phase 2: Roadmap. We build an interactive prototype with live data so you can click through every screen. This locks the scope for the fixed price.
What ships with every React frontend project
Every deliverable is production-ready and fully documented.
You own everything. Source code, design files, and infrastructure. We set up monitoring, analytics, and error tracking from day one.
No hidden dependencies. All components are built with standard React patterns so your internal team can take over anytime.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Vercel
- Unit tests (Jest) and integration tests (Cypress)
- Lighthouse performance reports (target 90+)
- Component documentation in Storybook
- Sentry error tracking and logging
- Post-launch monitoring dashboard (Datadog or Sentry)
