Ruby on Rails development is the design, build and support of web applications with Rails, the Ruby web framework. SynconAI builds SaaS products, marketplaces, subscription platforms and admin tools, upgrades Rails and Ruby versions, and supplies Rails engineers who join client teams, for organizations in the United States, Australia and worldwide. - Ruby on Rails is a web framework for Ruby, used for SaaS products, marketplaces and admin tools. - We build new Rails apps, take over existing ones and upgrade Rails and Ruby versions. - Work runs as a fixed-scope project, a dedicated team or Rails engineers who join your team. ## Ruby on Rails development services - New Rails products: SaaS products, marketplaces and MVPs built with tests from the first commit. - Features for existing apps: New billing, admin and customer features added to a live Rails app. - Rails APIs: JSON APIs for mobile apps and front ends, versioned and documented. - Rails and Ruby upgrades: Rails 5, 6 or 7 moved to 8.1, and Ruby moved to a supported version. - Performance and background jobs: Slow pages, N+1 queries and job queues fixed with Sidekiq or Solid Queue. - Hosting moves: Apps moved from Heroku to Kamal or containers on your own cloud. - Salesforce integration: Rails apps that sync customers and orders with Salesforce over its API. - Rails team extension: Rails engineers who join your team and work in your process. ## Where are you with Ruby on Rails? Question: What does your Rails work look like today? - Nothing built yet: A new Rails build. You have a product to launch and want Rails for speed of delivery. - Scope and data model agreed first - Hotwire or an API front end chosen early - Tests and CI from the first sprint - We inherited an app: Taking over an existing Rails app. The original developers or agency have gone, and changes feel risky. - Code, gem and security review - Test coverage added where it is thin - A written report and a plan - It is out of date: Upgrading or modernizing. The app runs on Rails 7.2 or older, an old Ruby, or Heroku. - Rails stepped up one version at a time - Ruby and gems moved to supported releases - Hosting reviewed and moved if needed Outcome: A Rails app on supported versions that your team can keep shipping ## What do our Ruby on Rails development services include? Build, take over, upgrade and staff Rails work with one team. - New Rails products: SaaS products, marketplaces and MVPs built with tests from the first commit. - Features for existing apps: New billing, admin and customer features added to a live Rails app. - Rails APIs: JSON APIs for mobile apps and front ends, versioned and documented. - Rails and Ruby upgrades: Rails 5, 6 or 7 moved to 8.1, and Ruby moved to a supported version. - Performance and background jobs: Slow pages, N+1 queries and job queues fixed with Sidekiq or Solid Queue. - Hosting moves: Apps moved from Heroku to Kamal or containers on your own cloud. - Salesforce integration: Rails apps that sync customers and orders with Salesforce over its API. - Rails team extension: Rails engineers who join your team and work in your process. ## The Rails stack we work with We follow Rails conventions and add gems only where they earn their place. - Front end (Pages without a heavy JavaScript build): Hotwire, Turbo, Stimulus - Application framework (Models, controllers and auth): Ruby on Rails, Ruby, Active Record, Devise - Jobs and data (Work that runs in the background): Sidekiq, Solid Queue, PostgreSQL - Testing and delivery (How changes ship): RSpec, Minitest, Kamal, Docker ## Which Rails versions are still supported? Rails 7.2 lost support in August 2026 and Rails 8.0 security fixes end on 7 November 2026. From then, Rails 8.1 is the only supported line. Today: Rails 7.2 or older on Ruby 3.2 or older - Rails 8.1, Upgrade Rails: Step through each version with tests passing at every stop, then deploy. After 7 November 2026, Rails 8.1 is the only line with security fixes. - Ruby 4.0, Upgrade Ruby: Move the app and its gems to a supported Ruby before or with the Rails upgrade. Ruby 3.2 reached end of life in March 2026. - Kamal or containers, Move off Heroku: Deploy with Kamal or containers on a cloud account you control. Heroku moved to sustaining engineering in February 2026, with no new features. ## How can you work with our Rails engineers? Three ways to engage. Each one is agreed in a written proposal before work starts. - Fixed-scope project, We deliver a defined Rails build or upgrade. - SynconAI directs the work to agreed milestones - Billed by milestone, as set out in the proposal - Working code, tests and a deploy you can repeat - Fits an MVP, a feature set or an upgrade - Dedicated team, A Rails team that works only on your product. - You set priorities, our lead runs the team - Billed monthly for the team - Engineers, a lead and testing as needed - Fits a product with a long, changing roadmap - Team extension, Rails engineers who join your team. - Your managers direct the day-to-day work - Billed monthly for each engineer - Vetted engineers, with employment and replacement handled by us - Fits teams with a working process that need more hands ## How does a Rails engagement start? Five steps from the first call to working code. - Brief: Call about your product and goals; Repository access or a written scope - Match or design: Engineers matched to your app; Plan and proposal in writing - Start: NDA, access and local setup; Codebase walkthrough and a first task - Build and review: Small pull requests merged often; Demos and code review with your team - Hand over or continue: Runbook and handover session; Or a monthly plan for ongoing work ## Cost and timing The first step is a free 60-minute architecture review of your Ruby on Rails setup, with a written plan you keep. Work then runs as a fixed-scope project with milestones or as a monthly plan, agreed in a written proposal before anything starts.
