Affordable Legacy Website Modernization ConsultantsModernization
We rebuild old, slow, insecure websites on modern stacks in 8-12 weeks. Fixed pricing from $80K with full ownership.
IRPR modernizes legacy websites using modern stacks like Next.js, TypeScript, and cloud-native architectures on AWS or GCP. We replace outdated codebases built on jQuery, PHP, or old .NET with fast, secure, and maintainable systems.
Projects typically run 8-12 weeks with fixed pricing between $80K and $250K depending on scope. All work is compliant with HIPAA, PCI-DSS, or SOC 2 where required.
We work with CTOs at mid-market companies stuck with a clunky website that hurts conversions. Digital product managers who need to migrate a legacy client-facing portal. And founders who inherited an outdated SaaS platform that can't scale.

Why modernize your legacy website?
Outdated websites cost you money and security.
A legacy website built on old tech like jQuery, PHP 5, or .NET Framework is slow, insecure, and hard to maintain. Each month you delay, you risk security breaches and lost conversions from slow load times.
IRPR has rebuilt over 200+ legacy sites using modern stacks. Our clients see an average 40% increase in page speed and a 25% lift in conversion rates after migration.
Generic dev shop vs IRPR
Most agencies sell you hourly work with no deadline. IRPR gives you fixed price and on-time delivery.
Typical dev shops use hourly billing and treat your project as just another contract. They often lack experience with compliance or modern frontend frameworks.
IRPR delivers a fixed price, a clear roadmap, and a migration strategy that minimizes risk. We guarantee the codebase meets your security and compliance needs from day one.
- Hourly billing with no cost cap
- No fixed timeline - projects drag on
- Rewrite the entire site from scratch
- No compliance knowledge (HIPAA, PCI)
- Often uses outdated frameworks like jQuery
- No post-launch support or monitoring
- Fixed price from $80K to $250K
- 8-12 week roadmap with milestones
- Incremental migration - reduce risk
- Built-in HIPAA, PCI, SOC 2 compliance
- Modern stack: Next.js, TypeScript, AWS
- CI/CD pipeline and Sentry monitoring included
Our 4-phase modernization process
We follow a proven process to move your legacy website to a modern stack without breaking things.
Phase 1: Audit and Roadmap. We analyze your current codebase, infrastructure, and security gaps. Delivers a detailed migration plan with timeline and fixed price in week 2.
Phase 2: Incremental Build. We refactor one section at a time, using feature flags to keep the old site running. Each module is tested in staging before going live.
What ships with your modernized website
Every modernization project includes a full handoff package. No black boxes.
You get everything you need to run and update the new site without depending on us. We set up monitoring and alerts so you can sleep well.
All code is your property. We never lock you into a proprietary platform or license.
- Source code in your private GitHub repository
- CI/CD pipeline using GitHub Actions
- Automated unit and integration tests (Jest, Cypress)
- Sentry error tracking with performance monitoring
- Deployment on your own AWS or Vercel account
- Style guide and component library (Storybook)
- Lighthouse performance report with scores above 90
- Admin panel for content management (Sanity or Strapi)
- SSL certificate and CDN configuration
- Runbook and deployment documentation
