Why IRPR is the best UI frontend development agency
Our track record speaks for itself.
We have shipped over 200 products for clients in 50+ countries. Every project is delivered on time and within budget.
Our frontend teams work with React, Vue, and Next.js to create interfaces that users love. We follow strict accessibility standards (WCAG 2.1 AA).
The difference between average and exceptional frontend
Not all agencies deliver the same quality.
Generic dev shops often cut corners, leading to inconsistent UI and slow performance. IRPR follows a systematic approach to guarantee quality.
We build design systems, write automated tests, and optimize for Lighthouse scores above 90. Every project is documented and handed over cleanly.
- Hourly billing with no fixed scope
- No design system, inconsistent UI
- Slow load times and poor Lighthouse scores
- No automated testing, bugs slip through
- Unclear handoff, no documentation
- One-size-fits-all tech stack
- Fixed price with clear milestones
- Custom design system in Figma + code
- Performance budgets, Lighthouse 90+
- Full test suite: unit, integration, visual regressions
- Storybook documentation and style guide
- Tech stack chosen for your specific needs
