Migrating Outdated Websites to React or Next.js

Upgrade your website to modern, fast, and scalable frontend

Schedule a discussion What we build for complex businesses

Context

Many businesses still rely on outdated websites that are slow, hard to maintain, and not optimized for modern user expectations. This limits performance, SEO visibility, and future scalability.

Who this is for

We usually work best with teams who know building software is more than just shipping code.

This is for teams who

Businesses with outdated websites

Companies improving SEO and performance

Teams planning UI modernization

Organizations scaling their web platforms

Businesses reducing technical debt

This may not fit for

New projects without existing websites

Teams satisfied with current performance

Businesses not prioritizing SEO or UX

Simple static sites with minimal traffic

Problem framing

The operating reality

Legacy websites hold back growth and performance

Outdated tech stacks lead to slow load times, poor SEO, and difficult maintenance. Businesses struggle with inflexible codebases, weak mobile experiences, and security risks, making it hard to scale or improve their digital presence.

How this is usually solved (and why it breaks)

Common approaches

Continuing with legacy frameworks despite issues

Applying minor fixes instead of full upgrades

Ignoring performance and SEO limitations

Using outdated UI and design systems

Manual handling of code without modernization

Where these approaches fall short

Slow website speed and poor user experience

Low search engine visibility

High maintenance effort and costs

Limited ability to add new features

Increased security risks
