Our teammates Evaldo Klock and Jaison Coelho are having a blast at Tropical on Rails in Brazil this week!
What starts as simple reporting can quietly become the slowest part of a Rails app.
Join our 30-minute Planet Argon LIVE webinar with Sergiu Truta next week to learn how to build efficient, maintainable reports with Rails.

We talk a lot about helping Rails apps evolve instead of starting over. This e-course shows how.

Some software can’t be paused.
When your system is in daily use, t The work has to happen while everything keeps moving.
With Walkenhorst’s, we helped prepare their Rails app for its next chapter without slowing down operations or disrupting everyday users.

Our CEO, Robby Russell, built a tool called Clarion that analyzes a ticket and surfaces relevant context from Jira, Confluence, & GitHub. Then it suggests clarifying questions before development even starts. He wrote up the full breakdown on his blog, Robby on Rails.

A rewrite was planned.
Newspaper Club was preparing for a Shopify migration, and their internal dev team was transitioning out. Meanwhile, their Rails app still needed to work. So they brought us in to keep things steady. But was a migration really necessary?

What questions "should" we be asking about maintaining mature apps? Our CEO, Robby Russell, recently appeared on the "Overcommitted Podcast" to chat about sustaining software projects, killer docs/testing habits, and nailing work-life balance in tech.

Ruby 4.0 marks a new chapter for the ecosystem.
For teams running mature Rails apps, it’s also a moment to ask: Is our application ready for its next act?
A code audit helps teams understand what's happening in the codebase without guesswork.

Your Rails app doesn’t need a fresh start. It needs consistent care.
The Maintainable Rails email course delivers one small, useful improvement each week. You'll learn to ask the right questions to make the simplest changes that make the biggest impact... and go from there! maintainablerails.com
We’re not here to tear things down or declare everything broken. We believe in stewardship, helping teams evolve the systems that matter. Good software doesn’t need a rescue. It needs a thoughtful path forward.
Support shouldn't feel like outsourcing. We want collaboration to feel natural. Like having another steady pair of hands... not a vendor across the ocean. When communication feels easy and progress feels shared, the work moves more steadily.
We’ve met teams who love their app but dread touching certain parts of it. You deserve to feel the opposite: That your app is sturdy, understood, and ready for what’s next. Our favorite moment is when a team looks at their codebase with pride again.
If your app has survived more than one rewrite rumor, you’re our kind of developer.
Learn how to improve performance, reliability, and team sanity—one practical tip at a time.

Every mature Rails app leaves clues about where it wants to evolve. Slow spots. Old dependencies. Tests that flinch when touched. The end of the year is the perfect moment to listen. Improvement rarely starts with a rewrite; it starts with paying attention.
We don’t believe in pressure or panic. We believe in guidance. We believe in making complicated decisions feel lighter. If you feel more grounded after talking with us, then we’re doing it right.
A good partner doesn’t just fix code. They help you feel confident about where your app is headed. When you feel clear and supported, it’s easier to plan. Easier to decide. Easier to move forward. www.planetargon.com/contact
A good Rails app isn’t fragile. It’s layered. If your app feels unwieldy at the end of the year, that doesn’t mean it's broken. It means it has history. It has context AI can’t guess.
The opportunity in 2026 isn’t to start over... It’s to make the next layer smarter than the last.

Your app feels complicated because it’s been loved. If it were simple, it wouldn’t have survived this long. We’ve never met a mature codebase that didn’t have quirks, mysteries, or inside jokes. That’s part of the charm. And part of the opportunity.
This is the time of year when teams ask, “Do we need to just rebuild this thing next year?”
Usually, the answer is no. Good software deserves a fresh plan, a few key upgrades, and renewed clarity to carry it forward without burning it down.
Something new is coming from the Planet Argon team.

You can’t catch someone up on 10 years of decisions in one meeting. And you shouldn’t have to. The right partner doesn’t rush into solutions. They spend time learning the rhythms, the patterns, the history. Because every system has a legacy worth understanding.
Small changes in your habits can keep your Rails app running years longer than you expected.

Most of the time, what your system needs isn’t a rewrite.
It needs care. Clarity. A plan for what’s next.
Your app has history. Let’s make sure it has a future.
At Planet Argon, we help teams evolve the software they already depend on.
Because good software deserves a second act.
Another year is wrapping up.
And somewhere, someone on your team is asking if it’s time to rewrite the app.
It’s a familiar question. The clean slate always sounds appealing.
But it also means starting over, relearning what you already know, and hoping it goes faster this time.
🎤 Productions Plus had a big idea: a custom tool to track the impact of face-to-face brand experiences—without invading anyone’s privacy. We designed it, built it, and launched it together.
