New to Ruby on Rails development?
What is Ruby on Rails development?
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.
Starting point
Where are you with Ruby on Rails?
What does your Rails work look like today?
- Path 01Nothing 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
- Path 02We 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
- Path 03It is out of date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
A Rails app on supported versions that your team can keep shipping

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.

Engagement
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
Process
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
What it costs and how long it takes
The review is free
A 60-minute architecture review of your Ruby on Rails setup, with a written plan you keep.
A fixed-scope proposal first
Before any work starts you get a written proposal: a fixed-scope project with milestones, or a monthly plan. You approve it, or you do not.
Timing follows scope
How long it takes depends on what is in scope. The proposal states the milestones, so you see the timeline before you commit.
