Upgrade the Rails app without stopping the product.

Your Ruby on Rails app runs on a version that is past or nearing end of life. You have read that staying there is a security and hiring risk, and you are probably right. But the quotes you get treat the upgrade like a months-long freeze where nothing else ships, and you cannot afford to put the roadmap on hold to chase a version number. The good news: a Rails upgrade rarely needs to be a big-bang event, and sometimes it is not the thing you actually need at all.

Let's Talk

When you may not need a full upgrade

Most upgrade shops are paid to upgrade, so they upgrade. We start somewhere else: do you actually need this right now? Sometimes the right move is a targeted security-patch path on your current major version, not a jump. Sometimes one or two risky dependencies are the real exposure, not the framework itself. We will tell you when a smaller, cheaper fix buys you the safety you came for, and when the version really is the problem. That honesty is the whole point, and it is why founders come back.

Here is the rough end-of-life picture we work from. Rails 6 and earlier receive no official security fixes. Within Rails 7, only the latest minor is still inside its security-fix window, and that window closes in 2026 - Rails 7.1 and earlier are already end of life and getting no patches, which is why apps on those versions missed the security fixes shipped in 2026. Rails 8 is the current, supported line. If you are on Rails 7.1 or below, you carry real, unpatched risk right now. If you are on a current release, you may simply need maintenance, not a project. We confirm your exact version, dependencies, and the live security-support status before recommending anything.

What we do

When an upgrade is the right call, we do it incrementally. The first step is a short audit, usually one to two weeks: your current version, the dependency graph, the gems that will fight the jump, and the test coverage you have to protect the work. If coverage is thin, we backfill it first with AI-assisted test generation, so the upgrade has a safety net and your users never become the test suite.

Then we move in stages, one safe increment at a time, with the app shipping the whole way. Rails 4 to 5 to 6 to 7 to 8 is a path, not a leap, and we keep your roadmap moving alongside it. One named senior engineer owns the work end to end, so there is no handoff and no one learning your app on your budget.

Proof, not adjectives

We have lived in long-running Rails codebases for years, not just visited them. Volodymyr brings 17+ years of Rails depth, from authoring early versions of products like MoveitPro (2,000+ moving companies today) to leading teams on large Rails systems. VeViDi has been the ongoing engineering team behind LionWheel (1,000+ businesses worldwide, 4.8/5 on G2 and Capterra) and stabilized an inherited live fintech product (under NDA) to the point of zero error alerts for months. We know what a healthy modern Rails app looks like, because we keep several of them healthy.

The economics

Version upgrades used to be priced as full-team, multi-month projects. With senior judgment plus AI amplification, reading the codebase and generating the missing tests take a fraction of that effort, which changes the cost and the timeline. And the day-to-day math has shifted too: an in-house developer now costs salary plus a monthly AI tooling bill, while one senior engineer with AI amplification through us can come in under the cost of the local hire alone. The exact number depends on your version, your dependencies, and your market, so we scope it honestly first.

Who this is not for

If you are on a current Rails version and just want routine maintenance, you may not need an upgrade engagement at all, and we will say so. If you want a body to sit on the project indefinitely with no defined endpoint, we are not the fit. We take upgrades where senior judgment changes the outcome and protects a product that real customers use.
