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.
What our clients are saying about us
Jonathan Silver
Digital Marketing Director at West Dermatology
While their approach to customer serivce and client relations is great, what I actually found most impressive was their ability to help develop solutions in creative ways. None of the complex content issues were a problem, and the team was always open to new information/new requirements regardless of where we were in the process.

Planet Argon was a top-notch partner agency that provided a great service experience. They truly recognized the importance of e-commerce to our business. The team never overlooked an opportunity to engage consumers through the site.

Planet Argon is consistently responsive and delivers their tasks on time. They contact me when aspects of the project need to be discussed and provide me with a detailed approach to their plans and actions.
I am impressed at their ability to take on our multiple, complicated existing apps and learn them quickly and well, and quite happy with the numerous improvements they have made for us. Also, their attention to maintenance and support tasks, in addition to development, has been great.
