Legacy Website Modernization CompanyCompany
We replace outdated sites with modern, secure platforms in 8-12 weeks. Fixed price, senior engineers, no scope creep.
IRPR replaces legacy websites built on old frameworks like jQuery, PHP, or AngularJS with modern stacks: Next.js, React, Vue, and headless CMS platforms like Contentful or Strapi. We decouple the frontend from the backend so you can scale each independently.
A typical modernization project ships in 12-14 weeks with a fixed price from $80,000 to $250,000 depending on complexity. Every deliverable includes a CI/CD pipeline, automated testing, and compliance with HIPAA, PCI-DSS, or SOC 2 if needed.
Our clients are CTOs at SaaS companies stuck on monoliths, marketing directors at ecommerce brands losing revenue to slow page loads, healthcare IT managers needing HIPAA-compliant frontends, and media executives migrating from WordPress to headless CMS.

Why companies need a legacy website modernization company
Old code slows down your business. Here is what a modernization project delivers.
Legacy websites built on jQuery, PHP, or old AngularJS often have page load times above 5 seconds, scoring poorly on Core Web Vitals. Google penalizes slow sites in search rankings. A modern rebuild with Next.js static generation can cut load times to under 1.5 seconds.
Security vulnerabilities in legacy frameworks are a top reason for data breaches. IRPR upgrades all dependencies, enforces HTTPS, adds CSP headers, and runs automated penetration testing before launch. We also migrate complex forms and payment flows to Stripe or Braintree.
How IRPR vs generic dev shops handle modernization
Most agencies start coding without a plan. IRPR finishes projects on time and on budget.
A generic dev shop might charge hourly without a clear scope, leading to cost overruns and missed deadlines. IRPR uses a fixed price quote after a 2-week Roadmap phase where we document every page, API, and migration step.
Our senior engineers build test suites from day one. We use Cypress for end-to-end tests and Jest for unit tests so the final product works reliably on all browsers and devices.
- Hourly billing with vague scope
- Junior developers learning on your project
- No dedicated QA process
- Delays due to scope creep
- Delivered without documentation
- No post-launch support
- Fixed price after a 2-week Roadmap
- Senior engineers with 10+ years experience
- Automated CI/CD with 100% test coverage
- 12-14 week delivery on schedule
- Full technical documentation and handover
- 30 days free support after launch
Our legacy website modernization process
Four phases from audit to launch.
Every project starts with a website audit. We run Lighthouse, WebPageTest, and security scanners to identify every issue. Then we produce a Roadmap that details the new architecture, tech stack, and timeline.
In the Product phase, we build the modern site in sprints with weekly demos. The Release phase includes staging, user acceptance testing, and a cutover plan with zero downtime.
What ships with every modernization project
Every deliverable is production-ready and fully documented.
We do not hand over a zip file. You get a full codebase in your private GitHub repo with all commits, pull requests, and CI/CD pipelines configured for AWS or Vercel.
Documentation covers architecture decisions, API endpoints, environment variables, and deployment instructions. No tribal knowledge.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Sentry error tracking configured
- Cloud hosting on AWS, Vercel, or Netlify
- Automated end-to-end tests with Cypress
- Performance budget verified in CI
- Security headers and CSP configured
- Technical documentation in Notion or Markdown
- Content migration script for CMS data
- 30 days free post-launch support
What we ship in this practice.

Why teams hire us.
Fixed price after a 2-week Roadmap
Every modernization project gets a fixed quote in week 2. No hourly billing, no surprise invoices, no scope creep charges. The price you see is the price you pay.
Senior engineers only, no juniors
Every engineer on your project has 10+ years of experience. We do not staff juniors or offshore interns. The person who audits your site ships the code.
12-14 week delivery
A typical legacy website modernization ships in 12-14 weeks. We publish a sprint timeline in the Roadmap phase and hit every milestone.
100% code ownership
You own every line of code, every design file, and every documentation page. After launch, you can maintain it yourself or hire any team.
Compliance built in from day one
We handle HIPAA, PCI-DSS, and SOC 2 requirements as part of the build, not as an add-on. Security audits are included in every project.
30 days free post-launch support
After launch, we monitor uptime, fix any bugs, and answer questions for 30 days at no extra cost. Then we hand over a maintenance guide.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
