Ruby

Plenty of UK businesses are running a Ruby on Rails application that has quietly become critical: an internal tool, a booking system, a customer portal built years ago by a developer who has long since moved on. We maintain, modernise and extend those applications from our Southampton studio, and we build new ones where Rails is genuinely the right choice.

Ruby and Rails Services

1. Rescuing Inherited Applications

• 1

  Codebase audit

  A written assessment of what the application does, where the risk sits, and what it would cost to maintain, modernise or replace.

• 2

  Version upgrades

  Moving off end-of-life Ruby and Rails versions, one step at a time, with the test suite kept green throughout.

• 3

  Dependency and security patching

  Outdated gems carry known vulnerabilities. We bring the bundle up to date and keep it there.

2. Maintenance and Feature Work

• 1

  Ongoing support

  Bug fixes, small features and a named developer who understands your codebase, without hiring in-house.

• 2

  Test coverage

  RSpec or Minitest coverage added around the areas that change most, so releases stop being nerve-racking.

• 3

  Performance tuning

  N+1 query elimination, database indexing, caching and background job tuning where response times have crept up.

3. New Rails Builds

• 1

  Rapid internal tools

  Rails remains excellent for admin-heavy, database-backed applications where speed of delivery matters more than raw throughput.

• 2

  APIs behind modern frontends

  Rails in API mode serving a Next.js frontend, giving you a fast public site over a mature backend.

• 3

  Background processing

  Sidekiq and Active Job for imports, emails, reports and scheduled work that should never run in a web request.

4. Modernising Deployment

• 1

  Containerised releases

  Rails applications packaged with Docker so deployments stop depending on one specific server.

• 2

  Automated pipelines

  Tests, linting and migrations run automatically before a release reaches production.

• 3

  Migration paths

  Where Rails is no longer the right fit, we plan a staged move to Next.js or Go rather than a risky rewrite.

How We Quote Ruby Work

Inherited codebases vary enormously, so we start with a paid technical audit before quoting any ongoing work. Larger rebuilds run through our Custom Systems package (from £4,995). If the application is mainly a public-facing website, a rebuild on Authority Site (from £1,995) is often faster and cheaper than maintaining legacy Rails views.
