AI can write new code. Safely upgrading a decade-old Rails app? That takes experience.
Most Rails applications weren’t written yesterday. They’ve grown over years of features, integrations, and careful decisions.
Now, it's possible your Rails version is out of date. Rails 6.1 reached end of life in October 2024, which means no more security updates. Every month on an unsupported version is another month exposed to newly discovered vulnerabilities.
"But our app still works!" That’s usually why upgrades get delayed. However, every version you skip makes the next upgrade harder.
Safely upgrading a mature Rails application takes planning, testing, and experience. That’s where Planet Argon comes in.

What our clients are saying about us
Twila Rios
Manager of Digital Information Systems at Office of the General Convention
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.
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.

Working with Planet Argon has been a great experience. The transition from our previous provider to them was very smooth, and they took care of everything within a very short period of time. Moreover, our engagement has been successful because, thanks to them, our platform keeps growing. We’ve assigned them some development tasks, and we’ve been very pleased by how our site has been growing.
