FastRuby.io

FastRuby.io is a set of top-notch, productized services by OmbuLabs.ai that specializes in software maintenance, technical debt remediation, and performance optimization for Ruby and Rails applications.

We help teams keep legacy apps healthy, fast, and ready for what's next... without derailing your product roadmap!

What we do:

💵 Fixed-cost monthly maintenance

Whether you are running an outdated Ruby app (Hanami, Sinatra, or Roda) or a Rails app in production, we handle ongoing dependency updates, security patches, and steady modernization so your codebase doesn’t drift into “Rails Rescue” territory.

🚀 Performance optimization audits

If your Ruby or Rails app feels slow, fragile, or too costly to run, we’ll do a deep performance review, pinpoint the biggest bottlenecks, and deliver a prioritized action plan to improve speed, stability, and scalability.

🗺️ Ruby & Rails Upgrade Roadmaps

When you need a solid plan to get an upgrade approved, we produce a thorough roadmap with step-by-step actions, risk analysis, and realistic cost estimates (based on 50,000+ dev/hours of experience!)

🤖 Free AI-enhanced Rails upgrade roadmap

Our internal AI team created and maintains a free, comprehensive Rails upgrade roadmap that gives you a fast starting point for planning your next upgrade project.

🧹 Technical debt audits

For older Ruby and Rails codebases, we assess code quality hotspots, known security vulnerabilities, and maintainability issues, then recommend the highest-ROI fixes to nurture your app into "SOC2 compliance" territory.

🛠️ Open Source Tooling

We maintain and improve Ruby gems and upgrade tools like next_rails, bundler-leak, skunk, rubycritic, and more. We give back by helping teams everywhere diagnose issues, plan upgrades, and modernize safely.
