Why Established Companies Are Still Investing in Ruby on Rails Development

Every few years, a new framework arrives with bold claims that it will replace everything that came before it. Ruby on Rails has heard this prediction more times than almost any other technology in web development. And yet, in 2026, more than two decades after its first release, Rails is still running some of the most recognisable products on the internet, and companies are still choosing to build on it.

That is not nostalgia. It is a practical business decision, and the reasons behind it are worth understanding, especially for companies currently weighing their technology options.

A Framework That Has Outlasted Its Critics

Ruby on Rails was first released in 2004. Created by David Heinemeier Hansson while building Basecamp, it introduced ideas that are now considered standard across the web development world: convention over configuration, rapid prototyping, and a strong focus on developer happiness.

Over the years, Rails has gone through cycles of hype, criticism, and quiet resilience. It was declared “dying” around the rise of Node.js in the early 2010s, again when single-page application frameworks took over front-end development, and more recently as AI-assisted coding tools made people question whether framework choice even matters anymore.

Despite all of that, Rails has continued to power large-scale, high-traffic applications. The framework has also continued to evolve. Rails 8, released in 2024, introduced major updates including Solid Queue, Solid Cache, and Kamal for simplified deployment, reducing the need for external dependencies like Redis or Sidekiq in many setups. These updates were specifically aimed at making Rails simpler and cheaper to run at scale, a direct response to the operational complexity that pushed some companies toward other stacks in the past.

Companies Still Building on Rails in 2026

The clearest evidence of Rails’ staying power is the list of companies that continue to run significant parts of their infrastructure on it.

Company	How They Use Rails
GitHub	Core platform built and maintained on Rails since its early days
Shopify	Powers a large portion of its e-commerce platform, handling massive transaction volume
Basecamp	Original Rails application, still actively developed by Rails’ creators
Airbnb	Used Rails extensively in its growth years and retains parts of its stack on it
Zendesk	Customer service platform built on Rails
Square	Uses Rails across parts of its payments and business tools
Twitch	Early infrastructure built on Rails, with parts still in use
SoundCloud	Backend services built on Rails since launch

These are not small startups experimenting with a framework. These are companies processing significant transaction volume, user traffic, and data at scale. If Rails could not handle that level of demand, none of them would still be running on it.

Why Established Companies Keep Choosing Rails

There are specific, practical reasons why companies with the resources to use any technology stack continue to invest in Rails development.

Speed of development remains unmatched for many use cases

Rails was built around the idea that developers should not have to reinvent basic application structure every time they start a project. This convention-driven approach means teams can move from idea to working product significantly faster than with more flexible, configuration-heavy frameworks. For companies that need to ship features quickly without sacrificing code quality, this speed advantage has not gone away.

The ecosystem is mature and stable

Rails has thousands of well-maintained gems (libraries) covering nearly every common application need, from authentication to payment processing to background job handling. This maturity means fewer surprises and less time spent solving problems that other companies have already solved.

Maintainability over the long term

Codebases that follow Rails conventions tend to be easier for new developers to understand and maintain, even years after the original team has moved on. This matter enormously for companies running software for a decade or more, where the original engineering team is rarely the team still maintaining it.

Lower infrastructure costs

Many companies that moved toward complex microservice architectures in the 2010s have found themselves paying for that complexity in infrastructure costs and engineering overhead. Rails, particularly with the Rails 8 updates that reduce dependency on external services, often allows teams to run a monolith efficiently without the operational burden of managing dozens of microservices.

Hiring is more predictable than people assume

While Rails developers are not as abundant as JavaScript developers, the talent pool is experienced. Most Rails developers have years of production experience, since the framework has not attracted the volume of bootcamp-trained beginners that some newer frameworks have. Companies often find that hiring fewer, more experienced Rails developers gets them further than hiring a larger team of less experienced developers in a newer stack.

What’s Driving Renewed Interest in Rails

A few specific developments have brought fresh attention to Rails in the past two years.

• Hotwire and Turbo: These tools let developers build fast, modern, app-like user interfaces without writing large amounts of JavaScript or adopting a separate front-end framework. This has made Rails attractive again for teams that want a snappy user experience without the complexity of maintaining a React or Vue codebase alongside their backend.
• Rails 8’s deployment simplification: Kamal, introduced as part of the Rails 8 release, makes it dramatically easier to deploy Rails applications to your own servers without relying entirely on expensive managed platforms.
• Reduced dependency stack: Solid Queue and Solid Cache remove the need for separate Redis instances for many applications, cutting both cost and operational complexity.
• AI-assisted development: Modern AI coding assistants tend to work especially well with Rails because of its consistent, convention-based structure. Predictable code patterns make it easier for AI tools to generate accurate suggestions, which have, somewhat unexpectedly, made Rails development faster in 2026 than it was even a few years ago.

Rails Compared to Modern Alternatives

For companies weighing their options, here is a practical comparison of how Rails stacks up against commonly considered alternatives.

Factor	Ruby on Rails	Node.js (Express/Nest)	Django (Python)
Development speed	Very fast for full-stack apps	Fast, but more setup required	Fast, similar conventions to Rails
Ecosystem maturity	Very mature, stable gems	Mature, but more fragmented	Mature, strong for data-heavy apps
Long-term maintainability	High, strong conventions	Varies by team discipline	High, similar philosophy to Rails
Talent pool experience level	Generally experienced	Wide range, more junior developers	Generally experienced
Infrastructure cost at scale	Low with Rails 8 updates	Can be efficient, depends on architecture	Moderate
Best fit	Full-stack apps, MVPs, SaaS products	Real-time apps, microservices	Data science-adjacent applications

No framework is universally better. The right choice depends on the specific product, team, and long-term goals. But this comparison shows why Rails remains a legitimate, competitive option rather than a legacy choice companies are stuck with.

When Rails Is the Right Choice (and When It Isn’t)

Rails tends to be the strongest choice for:

• SaaS products and web applications that need to launch quickly and iterate often
• Companies that want a full-stack solution without managing multiple separate codebases
• Teams that value long-term maintainability over short-term trend-following
• Businesses that want to control infrastructure costs as they scale

Rails is less suited for:

• Applications requiring extremely high concurrency with thousands of simultaneous real-time connections, where Node.js or Elixir may have an edge
• Teams building primarily around existing investments in a different language ecosystem
• Projects where the broader organisation has already standardised on a different stack for valid internal reasons

A good technology partner will tell you honestly when Rails is not the right fit, rather than pushing it as a default answer.

What Working with an Experienced Rails Partner Looks Like

The companies getting the most value from Rails in 2026 are not just using the framework. They are working with development partners who understand how to apply modern Rails practices, including Hotwire-based interfaces, Rails 8 deployment improvements, and clean, maintainable architecture from day one.

A capable team will start with a clear assessment of your product goals, recommend an architecture that fits your scale and growth plans, and build with maintainability in mind rather than just shipping quickly and leaving technical debt for later. This is the same discipline that applies across any serious custom software development engagement, regardless of which specific framework ends up being the right fit.

For companies specifically considering Rails, working with a team that has handled Ruby on Rails projects across different industries and scales makes the difference between a smooth build and a costly rebuild eighteen months later.

Final Thoughts

Ruby on Rails has outlived more “framework killers” than almost any other technology in web development, and it has done so by continuing to solve real problems for real companies. The businesses still investing in it are not doing so out of habit. They are doing so because Rails continues to deliver fast development, strong maintainability, and increasingly, lower infrastructure costs thanks to recent updates.

For founders and technical leaders evaluating their next build, the question is not whether Rails is outdated. The track record clearly says otherwise. The real question is whether your specific product and team are the right fit for what Rails does best, and that is a conversation worth having with people who have built on it for years, not just read about it.
