Best React Frontend Development VendorDevelopment Vendor
Build fast, scalable UIs with senior React engineers. We ship production-ready frontends in 8-12 weeks with fixed pricing.
IRPR is the best react frontend development vendor for companies that need production-grade UIs. We use React 18, Next.js 14, TypeScript, Redux Toolkit, and Tailwind CSS to build interfaces that load fast and scale to millions of users.
Every project starts with a 2-week Roadmap phase where we define scope, architecture, and a fixed price. Typical frontend builds run 8-12 weeks and cost between $80K and $250K. We follow WCAG 2.1 AA accessibility standards and ship with full unit and E2E test coverage using Jest and Cypress.
Founders hire us when they need a polished MVP for their seed round. CTOs bring us in to replace a broken React codebase with a maintainable monorepo. Product teams outsource complex component libraries when their in-house team is stretched thin.

How IRPR differs from other React agencies
Most frontend shops charge by the hour and deliver incomplete code. We do it differently.
The difference starts with our Roadmap phase. In week 2, we deliver a detailed scope document with wireframes, component tree, API contracts, and a fixed price. No surprises, no budget blowouts.
We assign 2-3 senior React engineers per project, each with 6+ years of experience. They work synchronously with your team during Eastern Time business hours. We never offshore to junior devs.
- Hourly billing with no cap
- Junior or outsourced developers
- No written scope before coding starts
- Delivers untested code without CI/CD
- Uses deprecated React patterns
- No accessibility or performance guarantees
- Fixed price after 2-week Roadmap
- Senior engineers with 6+ years React
- Detailed scope and architecture document
- 100% test coverage, CI/CD pipeline on GitHub Actions

Fixed price, not hourly
Every React project gets a fixed quote after the 2-week Roadmap phase. No hourly billing means no budget surprises. Our average frontend project costs $80K-$250K total.
Senior engineers only
We assign 2-3 React engineers with 6+ years of experience per project. No junior developers, no outsourced gig workers. Our team averages 8 years of professional React experience.
Tested before it ships
Every component has Jest unit tests and every user flow has Cypress E2E tests. We enforce 80% minimum code coverage. Bugs get caught before production deployment.
Accessible by default
All our React frontends meet WCAG 2.1 AA standards. We test with screen readers (JAWS, NVDA) and check color contrast ratios. No accessibility audits pass without fixes.
CI/CD from day one
We set up GitHub Actions, Vercel preview deployments, and Sentry error tracking on the first sprint. Every pull request auto-deploys a preview URL for review.
30-day warranty included
After deployment, we fix any bugs discovered within 30 days at no extra cost. We also provide 8 hours of team handoff training. No handover fees, no retainer required.
