Legacy Website Modernization AgencyModernization Agency
We rebuild outdated web platforms into fast, secure, scalable products. Ship a modern MVP in 8-12 weeks for a fixed price.
IRPR modernizes legacy websites by re-architecting them with modern frameworks like Next.js, React, and Node.js. We migrate from outdated CMS platforms such as Drupal or WordPress to headless architectures using Sanity or Contentful.
Our standard timeline is 8-12 weeks with a fixed price between $80K and $250K. Every project ships with CI/CD, automated testing, monitoring, and compliance readiness for HIPAA, PCI-DSS, or SOC 2.
We work with CTOs at enterprises who need to replace monolithic systems, product managers at growing startups who want faster iteration, marketing directors demanding faster page load times, and compliance officers requiring a secure, modern platform.

Why legacy modernization needs experts
Outdated websites hurt your business in ways you can't afford to ignore.
A legacy website costs you in slow load times, security risks, and lost conversions. Every second of delay cuts conversion rates by 7%. IRPR has modernized over 200 websites, each delivering measurable improvements.
Our clients typically see a 50% reduction in page load time and a 35% decrease in bounce rate after migration. We use modern tooling like Lighthouse CI to verify performance every release.
Generic dev shop vs IRPR
Most agencies treat modernization as a rewrite from scratch. We treat it as a strategic upgrade with minimal risk.
A typical agency hands you a massive ballpark estimate and hopes for the best. You end up paying hourly for scope creep and technical debt.
IRPR delivers a fixed price after a 2-week Roadmap phase. We ship incrementally so you see progress every sprint, and we handle compliance and testing from day one.
- Rewrite from scratch with no migration plan
- Hourly billing with no cap
- Timeline slips by months
- Same tech stack as the old site
- Ignores compliance (HIPAA, PCI-DSS)
- Ends after launch with no support
- Incremental migration with rollback plan
- Fixed price after 2-week Roadmap
- 8-12 week delivery guarantee
- Modern stack: Next.js, Node, PostgreSQL
- Built-in HIPAA/PCI-DSS/SOC 2 readiness
- 30 days of post-launch monitoring and support
Our 4-phase modernization process
We break down legacy modernization into clear, predictable phases so you always know what happens next.
Phase 1 audits your current system end to end. We map every page, every API, every database table. You get a full report with performance metrics and technical debt.
Phase 2 produces a detailed roadmap with architecture, testing strategy, and a fixed price. Phases 3 and 4 are the build and release, each delivering a working increment.
What ships with every modernization
You get full ownership of the new platform and everything needed to run it, scale it, and maintain it.
We don't just hand over a finished site. We give you the infrastructure, documentation, and processes to keep improving it after we leave.
Every project includes the items below as standard deliverables. No extra cost, no hidden fees.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated test suite (Jest, Cypress)
- Performance budget with Lighthouse scores
- SEO audit and migration plan
- Accessibility compliance report (WCAG 2.1)
- Sentry error tracking
- Deployment runbook and rollback procedure
- 30 days of post-launch support
- Training session for your development team
