Best Frontend Development AgencyDevelopment Agency
We build fast, accessible, pixel-perfect frontends. 200+ products shipped, 8-12 week MVPs, fixed pricing.
IRPR is the best frontend development agency for founders and product leaders who need a production-grade UI fast. We use React, Next.js, Vue, TypeScript, and Tailwind CSS to build interfaces that load under 2 seconds and pass WCAG 2.1 AA.
Every frontend ships with a component library, automated visual regression tests, and a CI/CD pipeline. Typical MVPs take 8-12 weeks and cost between $80K and $250K. We comply with HIPAA, PCI-DSS, SOC 2, and FERPA where required.
Founders hire us when they need a polished MVP for a seed round. CTOs hire us when their internal team is overloaded. Product managers hire us to rebuild a legacy frontend that is slow and brittle.

Why IRPR is the best frontend development agency
We measure everything. Our track record proves we deliver.
IRPR has shipped over 200 frontend projects across 50 countries. Our on-time delivery rate is 98%. We use a fixed-price model so you know the cost before we write a single line of code. Every frontend we build goes through automated accessibility audits, visual regression tests, and performance budgets.
Our senior engineers average 10+ years of experience. They have worked at Google, Amazon, and Stripe. They know React, Vue, Next.js, and TypeScript inside out. We do not use junior developers or outsource to unknown teams. You get the same senior engineers from kickoff to deploy.
The difference between a generic dev shop and IRPR
Not all agencies deliver the same quality. Here is what sets us apart.
Generic dev shops often use junior developers, hourly billing, and no design system. They deliver code that works but is hard to maintain. You end up with a frontend that breaks on every browser update and fails accessibility checks.
IRPR builds production-grade frontends from day one. We use TypeScript, automated tests, and a component library. Every project includes a design system, visual regression tests, and performance monitoring. Your code is maintainable and scalable.
- Hourly billing with no fixed quote
- Junior developers with 1-2 years experience
- No design system or component library
- Manual testing only, no visual regression
- No performance budget or Core Web Vitals tracking
- No accessibility audits, fails WCAG 2.1
- Fixed price quoted in Roadmap phase (week 2)
- Senior engineers with 10+ years average experience
- Component library in Storybook with accessibility tokens
- Automated visual regression tests via Chromatic
- Performance budget with Lighthouse CI and Sentry
- WCAG 2.1 AA compliance on every project
Our frontend development process
We follow a four-phase process that guarantees clarity and speed.
Every project starts with a 2-week Roadmap phase where we define the tech stack, architecture, and exact scope. You get a fixed quote and a timeline. No surprises.
Then we build the frontend in 6-10 weeks. We ship a working MVP with a component library, tests, and CI/CD pipeline. You can review progress every 2 weeks.
What ships with every frontend project
You do not just get a website. You get a complete, production-ready frontend system.
Every project includes source code in your repository, a component library in Storybook, and a CI/CD pipeline on GitHub Actions. We also set up Sentry error tracking, Lighthouse performance monitoring, and automated accessibility checks.
You own everything. No lock-in, no licensing fees. You can deploy anywhere: Vercel, Netlify, AWS, or your own servers. We provide a handover document with architecture diagrams, environment variables, and deployment instructions.
- Source code in your private GitHub or GitLab repo
- Component library in Storybook with documentation
- CI/CD pipeline on GitHub Actions with automated tests
- Visual regression tests via Chromatic
- Sentry error tracking and performance monitoring
- Lighthouse CI with performance budget enforcement
- WCAG 2.1 AA accessibility audit report
