Trusted and top rated tech team
When Rails moved forward and your codebase didn't
Rails 8.1 replaced Sidekiq and Redis with Solid Queue, eliminated complex JavaScript build pipelines with Hotwire and Import Maps, and made Kamal the standard for containerized deployment. Most teams running Rails are still on version 6 or 7 with Webpacker, Sidekiq, and a frontend setup nobody wants to touch. Curotec engineers modernize Rails applications and build new ones on the stack the framework actually recommends now.
Our capabilities include:
- Rails 8.1 application development and architecture
- Legacy Rails modernization and version upgrades
- Hotwire and Turbo migration from complex JavaScript frontends
- Solid Queue, Solid Cache, and Solid Cable implementation
- API-first Rails backends for mobile and decoupled frontends
- Kamal deployment configuration and containerized infrastructure
Who we support
Curotec works with engineering teams and companies across the Rails ecosystem — whether you’re maintaining a legacy codebase, building a new product, or augmenting a team that needs senior Rails engineers who know the modern stack.
Teams on Legacy Rails Codebases
Your application runs on Rails 5 or 6 with Webpacker, Sidekiq, and a JavaScript setup nobody fully understands. Every upgrade surfaces breaking changes across gems and custom code that predates modern Rails conventions. You need engineers who can stage the migration to Rails 8.1 without freezing the features your business depends on.
Startups and SaaS Companies on Rails
Your product is moving fast but the architecture decisions from the first six months are starting to slow you down. Background jobs are unreliable, caching is inconsistent, and the frontend is a mix of legacy jQuery and a half-finished React integration. You need engineers who can clean up the stack and build what's next on Solid Queue, Hotwire, and Turbo.
Organizations Needing Rails Depth
Your team ships features but nobody owns the Rails infrastructure. Solid Queue configuration, Kamal deployment setup, and Action Cable or Solid Cable decisions keep getting deferred. You need senior Rails engineers who can make those architectural calls, implement them cleanly, and hand everything back fully documented.

Ruby on Rails tools and technologies we work with
Core Framework
Our engineers use Rails 8.1 and Ruby 3.3, following modern conventions to reduce gem dependencies and operational overhead.
- Rails 8.1 – Current framework release with built-in authentication, Solid Queue, Solid Cache, and Solid Cable reducing reliance on external services
- Ruby 3.3 – Latest stable Ruby release with YJIT performance improvements, pattern matching enhancements, and improved concurrency via Fibers
- Active Record – Rails ORM with encryption, async queries, and composite primary key support added across recent major versions
- Action Mailer – Built-in email framework for transactional emails with template rendering, multipart support, and queue-backed delivery via Solid Queue
- Active Storage – File upload and attachment framework with direct cloud uploads, image transformation, and mirroring across storage services
- Devise – Authentication gem for applications requiring full user management beyond Rails 8’s built-in authentication generator
Frontend and UI
We build Rails frontends with Hotwire and Turbo so teams ship interactive UIs without a separate JavaScript framework or build pipeline.
- Hotwire – Rails-native frontend approach combining Turbo and Stimulus for SPA-like interactions without writing a separate JavaScript application
- Turbo – Handles page navigation, form submissions, and partial page updates over the wire, eliminating full-page reloads without custom JavaScript
- Stimulus – Lightweight JavaScript framework for adding targeted interactivity to HTML elements rendered by Rails without a component-based frontend architecture
- Import Maps – Browser-native JavaScript module loading that ships Rails applications without a Node.js build pipeline or bundler configuration
- Propshaft – Modern Rails asset pipeline replacing Sprockets with faster digesting and simpler configuration for CSS and JavaScript delivery
- Vue.js – Frontend framework used with Rails API backends for teams that need a full component-based SPA alongside their Rails application
Background Jobs and Real-Time
Curotec configures Solid Queue, Solid Cache, and Solid Cable so Rails handles jobs and real-time features without Redis or external services.
- Solid Queue – Database-backed background job processor replacing Sidekiq and Redis with a simpler, lower-overhead queue built into Rails 8
- Solid Cache – Stores cached data in your existing database, replacing Redis for most caching needs without adding infrastructure complexity or operational overhead
- Solid Cable – Action Cable adapter that uses your database as the pub/sub backend, eliminating the Redis dependency for real-time WebSocket features in Rails
- Sidekiq – Redis-backed background job processor for high-throughput queue workloads that exceed what Solid Queue’s database approach can handle efficiently
- Action Cable – Built-in Rails WebSocket framework for real-time features like notifications, chat, and live updates across connected browser clients
- Redis – In-memory data store used with Sidekiq and Action Cable on high-throughput Rails applications where the Solid trifecta isn’t sufficient
Testing and Code Quality
Our developers configure RSpec or Minitest with FactoryBot, Rubocop, and parallel execution for every Rails project.
- RSpec – Behavior-driven testing framework for Rails with expressive syntax, shared examples, and matchers configured for model, controller, and request specs
- Minitest – Rails’ default testing framework used for fast, lightweight unit and integration tests with parallel execution support built into the test runner
- FactoryBot – Test data factory library for generating Rails model instances with trait-based variation and association handling across complex test suites
- Capybara – Acceptance testing framework that simulates browser interactions for Rails integration and system tests without requiring a full browser driver
- Playwright – End-to-end testing for Rails frontends including Hotwire-driven UIs, covering authenticated flows and JavaScript interactions in real browser environments
- Rubocop – Ruby static analysis and code style enforcement configured with Rails-specific cops to maintain consistent code quality across the entire codebase
Deployment and Infrastructure
Curotec configures Kamal or Capistrano to create zero-downtime Rails deployments that fit your hosting environment and release workflow.
- Kamal – Docker-based deployment tool from the Rails team for zero-downtime containerized deployments to any cloud or bare metal server without a managed platform
- Capistrano – Traditional Rails deployment tool for managing releases, rollbacks, and multi-server deployments on VPS and dedicated server infrastructure
- AWS – Rails deployments on EC2, RDS, and ElastiCache with infrastructure defined in Terraform for repeatable, auditable production environments
- Docker – Container builds for consistent Rails development environments and production parity across local, staging, and production infrastructure
- GitHub Actions – CI/CD pipelines for automated Rails deployments covering RSpec runs, Rubocop checks, and environment promotion from staging to production
- Heroku – Managed Rails hosting for teams that prioritize deployment simplicity over infrastructure control, with add-ons for PostgreSQL, Redis, and monitoring
Database and Storage
We configure ActiveRecord and PostgreSQL with query optimization, full-text search, and caching to match your application’s data needs.
- PostgreSQL – Primary database for production Rails applications with full-text search, JSONB columns, and advanced indexing for complex query optimization
- SQLite – Production-viable database for Rails 8 applications where single-server deployments reduce operational costs without sacrificing performance at scale
- Active Record Encryption – Built-in Rails column-level encryption for sensitive data fields without external key management services or custom encryption logic
- PgHero – PostgreSQL performance dashboard for identifying slow queries, missing indexes, and connection pool issues in production Rails applications
- Elasticsearch – Full-text search integration via Searchkick for Rails applications requiring advanced search, faceting, and relevance tuning beyond PostgreSQL’s capabilities
- Active Storage – File attachment framework for Rails with direct uploads to S3, Google Cloud Storage, and Azure with built-in image transformation support
FAQs about our Ruby on Rails services
Should we migrate from Rails 6 to Rails 8?
Almost always yes. Rails 8.1 replaces Redis with Solid Queue and Solid Cache, modernizes the frontend with Hotwire, and simplifies deployment with Kamal. We stage the migration across versions so your team keeps shipping throughout the process.
Do we still need Redis with Rails 8?
Not for most use cases. Solid Queue, Solid Cache, and Solid Cable replace Redis for background jobs, caching, and WebSockets. High-throughput applications may still benefit from Redis, but most teams can remove it entirely.
Should we switch from Rails to Node.js?
Usually no. If your team knows Rails and your application is already built on it, switching frameworks is a rewrite with a different name. Rails 8.1 handles concurrency, real-time features, and API workloads that used to require Node.js.
Can Rails handle our API backend needs?
Yes. Rails API mode strips out browser middleware and delivers a lean JSON backend with versioned endpoints, token authentication via Devise or built-in auth, and serializers matched to your frontend’s data requirements.
How do you approach Rails version upgrades?
We audit gem compatibility, deprecation warnings, and breaking changes before touching the codebase. Upgrades are staged one major version at a time with test coverage added where it’s missing so regressions surface before production.
How do your engineers work with our team?
We work in your repo, follow your branching conventions, and write RSpec or Minitest tests as a standard deliverable. Architecture decisions get documented so your team owns what we build after the engagement ends.
