Ruby on Rails Development Services
And we've been doing it since 2009.
Some teams pick up Rails for a project and move on. We didn't. Ruby on Rails development is all we do — and after 15+ years, we've gotten pretty good at it. Whether you need a custom Rails application built from scratch or want to extend an existing one, we bring senior engineers who know the framework inside out.
What we can build for you
Custom Rails development
SaaS products, internal tools, customer-facing platforms — we've built them all in Rails. We handle the full stack: architecture, backend, frontend with Hotwire, background jobs with Sidekiq, the works.
- Full-stack architecture
- Hotwire & modern frontend
- Background processing
- CI/CD & documentation
MVPs that don't fall apart
We've built MVPs that went from first commit to production in weeks — and then stayed in production for years. We don't build throwaway prototypes.
- Rapid time-to-market
- Production-grade from day one
- Scalable architecture
- Iterative development
APIs and integrations
Need a backend for your mobile app or a third-party integration? We build Rails APIs that external teams can actually work with.
- RESTful API design
- API documentation
- Third-party integrations
- Versioning & reliability
Rails upgrades
Running an older version? We upgrade Rails applications incrementally — version by version, with zero downtime. We've done upgrades from Rails 2.x all the way to 8.x.
- Incremental upgrades
- Zero-downtime strategy
- Gem compatibility fixes
- Test suite restoration
Our process is simple
We talk
A 30-minute call where we listen to what you need. No sales pitch — we'll tell you honestly whether Rails is the right choice.
We plan
Before writing code, we map out the architecture, define the data model, and agree on priorities.
We build
Two-week sprints. Working software at the end of each one. You see real progress, not status reports.
We ship — and stay
We don't disappear after launch. We deploy to production, set up monitoring, and stick around.
Why we chose Rails (and keep choosing it)
Proven at scale
Rails powers GitHub, Shopify, Basecamp, and thousands of production applications. It's built for developer productivity — your project moves faster without sacrificing quality.
Mature ecosystem
170,000+ gems, battle-tested solutions for authentication, payments, search, background processing. Most problems you'll encounter have already been solved.
It scales
The 'Rails doesn't scale' myth died years ago. With proper architecture, Rails handles millions of requests per day.

What does a Ruby on Rails development company actually do?
A Ruby on Rails development company builds web applications using the Rails framework. This includes custom SaaS products, internal business tools, APIs for mobile apps, e-commerce platforms, and more. At USEO, we handle the full lifecycle — from architecture and development through deployment, monitoring, and long-term maintenance. We also rescue and upgrade existing Rails applications that have fallen behind on versions or accumulated technical debt.
How do I choose the best Ruby on Rails development company?
Look for specialization, not generalization. The best Rails development companies focus primarily on Ruby on Rails rather than offering it as one of twenty technologies. Check how long they've been working with Rails, ask about team seniority (juniors vs. seniors), and look for long-term client relationships — not just project-based work. At USEO, we've worked exclusively with Rails since 2009, our team is senior-only, and our longest partnership spans 12+ years.
What Ruby on Rails development services do you offer?
We offer four core services: (1) Custom Rails application development — full-stack builds for SaaS, internal tools, and platforms. (2) MVP development — production-grade minimum viable products that scale. (3) API development — RESTful APIs for mobile backends and third-party integrations. (4) Rails upgrades — incremental version upgrades from 2.x through 8.x with zero downtime. We also provide ongoing maintenance and support for all applications we build.
How much does Ruby on Rails web development cost?
Cost depends on project scope and complexity. A Rails MVP typically starts at $25K-$50K. A full-featured SaaS application ranges from $50K-$150K+. Rails upgrades run $15K-$50K depending on the version gap. We work on a time-and-materials basis with two-week sprints, so you have full visibility into costs and can adjust scope as needed. We provide a detailed estimate after our initial consultation — no surprises.
Do you offer a free architecture audit?
Yes. Before any engagement, we offer a free 30-minute consultation where we discuss your project requirements and provide an initial technical assessment. For existing Rails applications, we can perform a more thorough architecture audit that covers code quality, security, performance, and upgrade paths. This audit gives you a clear picture of where your application stands and what it would take to improve it.
Is there any vendor lock-in when working with USEO?
No vendor lock-in. All code belongs to you from day one. We use standard Ruby on Rails conventions, open-source tools, and well-documented patterns. Any competent Rails team can pick up where we left off. We keep clients by delivering results — our longest partnership is 12+ years — not by creating dependencies. We even document our architectural decisions so future teams understand the 'why' behind our choices.
Can you work with our existing team?
Absolutely. We frequently embed our senior Rails developers into existing teams. We adapt to your workflows — your Git branching strategy, your code review process, your communication tools. Whether you need us to lead development or support your in-house team with specialized expertise, we integrate seamlessly. We've done this successfully with teams in the US, UK, Switzerland, and across Europe.
Where is your Ruby on Rails development company based?
USEO is based in Wroclaw, Poland (CET timezone). We have 6+ hours of daily overlap with US East Coast teams, making real-time collaboration comfortable. We've worked with clients across the US, UK, Switzerland, Germany, and Australia. All communication is in English. Our Clutch rating is 5.0, and we've maintained client partnerships spanning over a decade.
