Website Modernization VendorModernization Vendor
We rebuild legacy sites on modern stacks in 12 weeks. Fixed price, full code ownership, no monthly retainers.
IRPR is a website modernization vendor that replaces outdated PHP, jQuery, or monolithic CMS sites with modern stacks like Next.js, Remix, or Astro. We migrate content to headless CMS platforms such as Contentful, Strapi, or Sanity, and deploy on AWS or Vercel for sub-100ms load times.
A typical modernization project takes 12-14 weeks and costs between $80,000 and $250,000 depending on scope. We handle compliance for HIPAA, PCI-DSS, and SOC 2, so regulated industries get a secure, modern site without cutting corners.
We work with CTOs who need to reduce tech debt, marketing directors who want faster page speeds for SEO, and product managers who need a headless architecture to support multi-channel content delivery. Every engagement starts with a fixed-price Roadmap phase in week 2.
Types of software we ship.
Headless CMS migration
Move from WordPress or Drupal to a headless CMS like Contentful or Strapi with a Next.js frontend.
Legacy PHP site rewrite
Replace a custom PHP or CodeIgniter site with a React or Vue SPA. Keep the database, rewrite the frontend.
Ecommerce re-platforming
Migrate from Magento or WooCommerce to Shopify Plus or a custom Next.js storefront with Stripe.
Enterprise portal modernization
Upgrade an AngularJS or old .NET portal to React with TypeScript and a micro-frontend architecture.
Static site rebuild
Convert a slow server-rendered site to a static site using Astro or Hugo. Deploy on a CDN for instant loads.
Progressive web app (PWA) upgrade
Add offline support, push notifications, and app-like performance to an existing website using Workbox and service workers.
API-first site architecture
Decouple the frontend from the backend by building a REST or GraphQL API layer. Enables multi-channel content reuse.
Performance audit + optimization
Run Lighthouse and WebPageTest audits, then fix render-blocking resources, lazy-load images, and implement code splitting.
We build for every business type.
Healthcare
Fintech
Ecommerce
Enterprise SaaS
Media & Publishing
Why companies hire a website modernization vendor
Legacy sites cost more in maintenance and lost revenue than a rebuild.
A site built on jQuery or AngularJS from 2015 has security gaps, slow load times, and no mobile optimization. Google Core Web Vitals updates penalize slow sites, dropping organic traffic by 30% or more. IRPR replaces these with modern frameworks that score 90+ on Lighthouse out of the box.
We also eliminate recurring technical debt. After a modernization with IRPR, you own clean TypeScript code, a headless CMS with structured content, and a CI/CD pipeline that deploys automatically. No more patching old plugins or fighting with outdated dependencies.
How IRPR differs from a generic dev shop
Most agencies charge hourly and hand you a fragile site. IRPR gives you a fixed price and a production-grade product.
Generic shops often start coding without a clear scope. They bill hourly, so scope creep means your budget balloons. The result is a site that works today but breaks on the next framework update.
IRPR starts with a 2-week Roadmap phase where we define every page, every component, and every API call in a written spec. You get a fixed price before we write a single line of code. The code is yours from day one, deployed with automated testing and error tracking.
- Hourly billing with no cap
- No written spec before coding starts
- Uses whatever framework the lead dev knows
- No automated testing in scope
- Delivers a zip file with no deployment pipeline
- You do not own the code unless specified
- Fixed price after a 2-week Roadmap
- Written spec with every component and API defined
- Modern stack chosen for your use case (Next.js, Remix, Astro)
- Cypress or Playwright tests included
- CI/CD pipeline on GitHub Actions or GitLab CI
- Full code ownership, deployed to your AWS or Vercel account
Our website modernization process
Four phases from audit to launch, each with a clear deliverable.
Phase 1 is the audit and Roadmap. We review your current site, run Lighthouse and WebPageTest, and map every page and integration. You get a written document with the full scope and a fixed price.
Phase 2 is build and migrate. We set up the headless CMS, migrate content via API, and build the frontend component by component. Each component is tested in isolation. Phase 3 is QA and load testing. Phase 4 is deployment with DNS cutover and a 30-day warranty.
What ships with every modernization project
You get more than a new frontend. The entire delivery system is yours.
Every IRPR modernization project includes a production-grade deployment pipeline, automated tests, and monitoring. You are not left with a static zip file and a handshake.
We also include a 30-day post-launch warranty where we fix any issues that arise. After that, you can continue with our team for ongoing maintenance or run everything yourself with the documentation we provide.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Sentry error tracking configured
- Lighthouse performance score 90+
- Automated end-to-end tests with Cypress
- Headless CMS setup with content models migrated
- Structured content export (JSON or CSV)
- Deployment guide and runbook
- 30-day post-launch warranty with SLA

Why teams hire us.
Fixed price from week 2
Every IRPR project starts with a 2-week Roadmap phase. You get a written spec and a fixed price before we write production code. No hourly billing, no surprise invoices.
Full code ownership
You own every line of code from day one. We deploy to your AWS, Vercel, or Cloudflare account. There is no platform lock-in and no licensing fees.
Senior engineers only
IRPR does not hire juniors. Every engineer on your project has 7+ years of experience. We do not outsource or use offshore teams.
Compliance built in
We handle HIPAA, PCI-DSS, and SOC 2 compliance as part of the build. Your new site is secure by default, not as an afterthought.
Performance guaranteed
Every site we ship scores 90+ on Lighthouse. We use Next.js static generation, image optimization, and CDN deployment to ensure sub-second load times.
12-week average timeline
Most modernizations ship in 12-14 weeks from kickoff. We use parallel workstreams and automated testing to keep the schedule tight.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
