Upgrade Your Rails App to the Latest Secure Version
Running on an outdated, unsupported version of Ruby on Rails? We bring legacy apps up to the latest stable release, detect every known vulnerability, and patch it — with zero downtime and no freeze on your roadmap.
No commitment · Written assessment · Fixed-scope estimate
An outdated Rails version is a liability
Once your Rails version reaches end-of-life, the official security patches stop. Every month you stay behind, the risk and the cost of catching up grow.
Rails upgrade & security services
End-to-end modernization for Ruby on Rails applications — from version upgrades to vulnerability patching.
Rails Version Upgrades
Move from any legacy version — Rails 2, 3, 4, 5, or 6 — up to the latest stable, secure release. Incremental, dual-boot upgrades that never block your team.
Security Audit & Patching
A full vulnerability scan of your application and every dependency. We surface known CVEs, unpatched gems, and insecure patterns — then patch them.
Gem & Dependency Modernization
Update, replace, or remove outdated and abandoned gems. We resolve version conflicts and shrink your dependency surface area.
Ruby Version Upgrades
Upgrade the underlying Ruby runtime for speed, security, and long-term support — fully tested against your suite before it ships.
Test Coverage & CI
We shore up the test suite before and during the upgrade so every change is verified, then stand up CI so you stay current going forward.
Performance & Stability
Capitalize on modern Rails internals — faster boot, lower memory, better concurrency — once you're on a current, supported version.
Find every vulnerability. Patch it.
We run a deep security audit across your application and its entire dependency tree, then fix what we find. You get a prioritized report and a hardened, patched codebase.
- Known CVEs in Rails and Ruby itself
- Vulnerable gems via bundler-audit & advisory databases
- Static analysis with Brakeman
- Insecure defaults & deprecated, removed APIs
- Exposed secrets and misconfigurations
- SQL injection, XSS, and CSRF exposure
A proven, low-risk upgrade process
Incremental, test-driven, and transparent at every step — so your business keeps moving while we modernize.
Audit & Assessment
We analyze your codebase, Rails and Ruby versions, dependencies, and test coverage — then deliver a written report of risks and a clear upgrade path.
Roadmap & Estimate
A prioritized, milestone-based plan with fixed checkpoints, so you know the scope, sequence, and cost before we write a single line of code.
Incremental Upgrade
Using a dual-boot strategy, we upgrade one version at a time behind the scenes — your team keeps shipping features the whole way through.
Test & Verify
Every step is validated against an expanded test suite and CI, so nothing regresses when it reaches production.
Deploy & Harden
We ship the upgrade with zero (or near-zero) downtime, patch outstanding vulnerabilities, and leave you with a maintainable, current stack.

Frequently asked questions
Everything you need to know about upgrading and securing your Rails app.
How long does a Rails upgrade take?
It depends on how many versions you're behind, the size of your codebase, and your existing test coverage. Most upgrades run from a few weeks to a couple of months. The free audit gives you a concrete timeline before you commit to anything.
Will the upgrade break my application?
No. We use an incremental, dual-boot approach and lean heavily on automated tests and CI, so each version jump is verified before it ships. Your app keeps running the entire time.
Can you upgrade a very old Rails app (Rails 2, 3, or 4)?
Yes. We routinely bring legacy applications from Rails 2, 3, and 4 all the way up to the latest stable release, one major version at a time.
What does the security audit cover?
We scan Rails and Ruby for known CVEs, check every gem against vulnerability advisory databases with bundler-audit, run static analysis with Brakeman, and review your app for insecure defaults, exposed secrets, and OWASP-class issues. You get a prioritized report and we patch what we find.
Do we have to stop feature work during the upgrade?
No. The dual-boot strategy lets your team keep developing and deploying features while the upgrade proceeds in parallel.
How much does it cost?
Every application is different, so we scope each engagement from the initial audit. You get a fixed, milestone-based estimate up front — no open-ended hourly billing.
