Next.js development for live applications
Next.js has changed a lot in a short time, and it hasn't stopped. Pages Router to App Router, server components, a caching model that got rewritten more than once, and a major version roughly every six months. If your app was built before a big change, it works, but each new feature request raises the question of which era of the framework you're building in.
That's the situation we often get called into. Someone needs a change shipped, and no one currently on the team can confidently say what it costs.
Our engineers work through the running application until we can answer that question, then we start shipping. Sometimes that means an upgrade first. Sometimes it means adding what you need in the patterns the app already uses and upgrading later.
Planet Argon has been working on other people's software since 2002. Our Next.js development services cover the whole application: the front end, the CMS behind it, the deploys, and the URLs you can't afford to break.
Let's chat about your app.
Some of the wonderful clients who have trusted us
Here's how we can help
Version Upgrades
We move applications across major Next.js versions, including Pages Router to App Router
Fast Feature Development
Add functionality to an existing Next.js codebase without a long ramp-up first
Rendering and Performance
Decide what renders on the server, what gets cached, and what the user waits for
Headless CMS Integration
Connect and extend the CMS so your team publishes without pulling in engineering
SEO and Discoverability
Build the metadata, structured data, and page structure that search engines and LLMs can read
Migrations Without Broken URLs
Move content or platforms while every existing URL keeps resolving where it always did
Keep the product, change the parts holding it back
Upgrading is not the same as rebuilding. We move applications forward one decision at a time, keeping what already works while replacing the parts that hold you back.
Your history is extremely valuable
Older pages carry your search rankings and every inbound link anyone ever made. We rebuilt the Ruby on Rails Community Survey on Next.js and kept all fifteen years of it reachable because the archive was the point.
Set your team up to publish on their own
Marketing waits on developers for page changes far too often. We model content so your team can compose pages themselves, and extend the CMS when the defaults don't fit their needs.
Your software deserves its second act
The application survived real users and real edge cases. That's not technical debt, that's evidence. We help you understand what you have, then make clear bets about what changes.
