Why IRPR is the best website modernization vendor
We deliver measurable results with a modern tech stack and fixed timelines.
Every website modernization project at IRPR starts with a 2-week Roadmap phase where we audit your existing codebase, performance metrics, and SEO. We then produce a detailed scope with fixed price and timeline.
Our average delivery is 12 weeks. We have shipped 200+ modernized websites across 50 countries, with 98% on time and 99.9% uptime post-launch.
The difference between generic dev shops and IRPR
Not all agencies deliver modernized websites that actually perform.
Generic agencies often use hourly billing, outdated stacks, and vague timelines. They deliver bloated code with slow load times and no post-launch support.
IRPR is different. We use a modern tech stack by default, provide a fixed price upfront, and guarantee a 12-week timeline. Every project includes full code ownership and 12 months of maintenance.

- Vague timelines and cost overruns
- Code ownership unclear
- No post-launch support
- Fixed price based on detailed roadmap
- Modern tech stack: Next.js, Tailwind, headless CMS
- Dedicated lead engineer and PM
- 12-week guaranteed timeline
- Full code ownership with private repo
- 12 months of maintenance included
How IRPR modernizes your website
A four-phase process that delivers a production-ready site in 12 weeks.
Phase 1: Audit & Strategy (2 weeks) - review existing codebase, performance metrics, SEO, and compliance requirements. Deliver a modernization roadmap with cost and timeline.
Phase 2: Architecture & Design (2 weeks) - design component library in Figma, set up headless CMS, choose tech stack (Next.js, Tailwind, TypeScript).
Phase 3: Build & Migrate (6 weeks) - rebuild frontend, migrate content, integrate APIs, set up CI/CD with GitHub Actions.
Phase 4: Test & Launch (2 weeks) - QA, load testing, SEO audit, production deployment with monitoring (Sentry, Datadog).
