Where Omaship fits.
Omaship is not only a starter kit. It gives Sokrates Omaship Skills, a trusted Rails foundation, and the creation and deployment layer for personal software, team workflows, and public applications.
Rails starters are useful when a developer wants a head start on a product. Omaship is aimed at a different job: giving agents skills and a repeatable path to create, inspect, deploy, and improve software without rebuilding the foundation every time.
Sokrates stays the personal agent people feel. Omaship is the trusted layer underneath: Omaship Skills, Rails structure, agent-readable context, deployment infrastructure, checks, and a path from private use to team use to public applications.
Full disclosure: we build Omaship. The other products here can be good choices for developer-led apps. Omaship is the choice when the foundation needs to be used by agents and still trusted by people.

Jumpstart Pro
jumpstartrails.com · By Chris Oliver & Jason Charnes
Jumpstart Pro is the most established Rails SaaS starter kit, maintained by Chris Oliver (GoRails) and Jason Charnes. It's a subscription product, meaning you get continuous updates as Rails evolves—a genuine advantage if you want to stay on the latest version without doing upgrade work yourself.
Feature-wise, it's the most comprehensive option. Multi-platform support (Rails + iOS + Android via Turbo Native), four payment providers (Stripe, Paddle, Braintree, PayPal), multitenancy, user impersonation, invoicing, announcements, OAuth, and i18n out of the box.
Strengths
- Most features of any Rails starter kit
- Continuous updates via subscription
- Multi-platform (web, iOS, Android)
- Four payment provider options
- Large community and active support
Trade-offs
- Subscription pricing = ongoing cost
- No deployment pipeline included
- No security scanning configuration
- Feature-rich can mean more to learn
Best for: Developers who want the most feature-complete starting point and value ongoing updates. Great if you're building a single ambitious product and want maximum flexibility in payment providers.
Bullet Train
bullettrain.co · By Andrew Culver
Bullet Train takes a different approach: it's an open-source Rails framework with optional paid add-ons. Its signature feature is "Super Scaffolding"—a code generator that creates production-quality views, not just database migrations. If your app is heavy on CRUD interfaces, this can save enormous time.
The framework includes a sophisticated roles and permissions system (CanCanCan-based), a theme engine with dark mode, REST API with OpenAPI docs, webhooks, and rich form field components. It's the most enterprise-ready option in the Rails ecosystem.
Strengths
- Super Scaffolding is genuinely unique
- Open-source core (free to start)
- Enterprise-grade permissions system
- OpenAPI-compliant REST API generation
- Theme engine with dark mode
Trade-offs
- Steeper learning curve than other options
- Heavier abstractions on top of Rails
- No deployment solution included
- Can feel "framework on a framework"
Best for: Teams building complex, CRUD-heavy applications that need enterprise-level permissions and API generation. Especially strong if your app manages many different resource types.
Omaship
omaship.io · This is our product
Omaship is the Rails creation and deployment layer Sokrates uses to create personal software, team workflows, and public applications. The core philosophy is still omakase: trusted defaults and reusable Omaship Skills so agents can build on patterns people can inspect and own.
What makes Omaship different from every other option on this list is scope. It does not just give you application code. It includes Omaship Skills for common app jobs, a Kamal 2.0 deployment pipeline, GitHub Actions CI/CD with security scanning (Brakeman, bundler-audit), and AGENTS.md context that lets agents inspect what exists before changing it.
For static, clear SaaS building blocks, Omaship can use engines behind the scenes. The skills decide when a solved piece belongs, so Sokrates can focus on creating the custom software instead of rebuilding auth, billing, teams, or other repeated foundation parts from scratch.
Sokrates is the first customer for this layer. Direct Omaship use also makes sense when a builder wants an agent-readable Rails foundation with deployment included.
Strengths
- Deployment included (Kamal + CI/CD)
- Omaship Skills for common app jobs
- AI-agent optimized (AGENTS.md, conventions)
- Engines for solved SaaS building blocks
- Security scanning in CI by default
Trade-offs
- Newer product, smaller community
- Starter (€249), Professional (€449), or Unlimited (€699) with one-time pricing
- More opinionated = less flexibility
- No mobile (iOS/Android) templates
Best for: Sokrates, agent builders, and teams that want skills, foundation, and deployment for personal software, team workflows, or public applications.
Sjabloon
getsjabloon.com
Sjabloon (Dutch for "template") is a clean, well-maintained Rails SaaS starter kit that's been around for several years. It focuses on providing solid defaults with Tailwind CSS integration, payment support for both Stripe and Lemon Squeezy, and a straightforward multi-tenancy setup.
Its strength is simplicity. If you want a clean Rails app with the basics done well and no heavy abstractions, Sjabloon delivers. It's particularly popular with European indie developers.
Strengths
- Clean, minimal codebase
- Lemon Squeezy + Stripe support
- Good Tailwind CSS integration
- Established track record
Trade-offs
- No deployment configuration
- Smaller feature set than Jumpstart Pro
- Less documentation available
Best for: Solo developers who want clean, sensible defaults without too many opinions. Good if you prefer Lemon Squeezy over Stripe.
Business Class
businessclasskit.com · by Josef Strzibny
Business Class is a Rails SaaS boilerplate that stays close to Rails defaults while adding Paddle Billing support, team-scoped CRUD generation, and Kamal deployment configuration. It was one of the first Rails templates with Paddle support, making it relevant for EU-focused SaaS billing workflows.
The enhanced CRUD generator handles team scoping and belongs_to associations, and includes tests for generated resources. It is practical and focused on builder productivity.
Strengths
- Paddle Billing support
- Team-scoped CRUD generator with tests
- Kamal deployment config included
- SEO-optimized blog engine
- Close to Rails defaults
Trade-offs
- No CI/CD pipeline included
- No automated infrastructure run execution
- Not optimized for AI coding agents
- Sidekiq instead of Solid Queue
Best for: EU-based founders who want Paddle Billing and a clean Rails codebase with team management.
Lightning Rails
lightningrails.com
Lightning Rails is a newer entrant from Dani (former Le Wagon Head of Product), priced aggressively at $70–$189. It provides a Rails SaaS template with Stripe integration, Devise auth with Magic Links, and notably includes multi-provider AI integration (OpenAI, Gemini, Claude) out of the box.
The UI layer uses DaisyUI with 20+ themes, giving you a polished look quickly. It also includes pre-filled legal pages, Cloudinary image hosting, and MotorAdmin for a quick admin dashboard. The focus is on getting an MVP out with maximum features at the lowest cost.
Strengths
- Aggressive pricing ($70–$189)
- Multi-provider AI integration built-in
- 20+ DaisyUI themes out of the box
- Magic Links + OAuth authentication
- Pre-filled legal pages
Trade-offs
- No deployment pipeline included
- No CI/CD or security scanning
- Newer, smaller community
- AI wrappers ≠ AI-agent-optimized codebase
Best for: Developers who want the most features for the lowest price and are comfortable setting up their own deployment. Great if you're building an AI-powered product that needs multi-provider API access.
RailKit
railkit.dev · Pre-launch (2026)
RailKit is a modular Rails 8 starter kit with a CLI-first approach. Instead of giving you one monolithic template, RailKit lets you install only the modules you need: Auth, Payments, Teams, AI, etc. Think of it as building blocks rather than a pre-built house.
It uses Kamal 2 for deployment—one of the few Rails starter kits that includes deployment out of the box. The AI module supports OpenAI, Claude, and Gemini. RailKit follows a dual-license model: open-source core with paid premium modules.
Strengths
- Modular: install only what you need
- CLI-first workflow
- Kamal 2 deployment included
- AI module with multi-provider support
- Open-source core
Trade-offs
- Pre-launch — not yet battle-tested
- Modular = more integration decisions
- No CI/CD or security scanning
- Premium modules pricing unclear
Best for: Developers who want maximum control over what's in their stack and prefer assembling components over using a pre-built foundation. Worth watching as it matures.
SaaS Pegasus
saaspegasus.com · Django (Python)
SaaS Pegasus isn't Rails—it's Django. We include it because if you're comparing SaaS boilerplates, you should consider whether Rails is the right framework for your project in the first place.
Pegasus is well-maintained with 1,800+ customers, starts at $99 (Hobby) up to $999 (Unlimited), and includes Stripe payments, teams, AI chat & agents (multi-provider LLM), a React or HTMX front-end option, Wagtail CMS, and excellent documentation. They've recently added AI-assisted development features including rules files for Claude and Cursor, plus MCP servers.
If your team is stronger in Python or you're building an AI-heavy product that benefits from Python's ML ecosystem, Pegasus is a strong choice. If you want Rails conventions, automated infrastructure, and $5/month self-hosting, that's where Omaship shines.
Strengths
- 1,800+ customers (strong social proof)
- Built-in AI chat, agents, and LLM integration
- AI-assisted development (Claude/Cursor rules, MCP)
- React or HTMX front-end options
- Wagtail CMS integration
- Excellent documentation
Trade-offs
- Not Rails (if you want Rails, this isn't it)
- Requires Redis/RabbitMQ for background jobs
- No automated infrastructure run execution
- No CI/CD or security scanning included
- Higher price ($449–$999 for full features)
Best for: Python developers building AI-powered SaaS products who want a comprehensive, battle-tested foundation.

railsfast.com · Rails 8
RailsFast positions itself as "The #1 Vibe Coding Template" and focuses on an opinionated Rails 8 codebase plus a guided onboarding flow. The setup guide is clear and practical, especially if you prefer following documented steps instead of wiring things yourself.
The core trade-off is that infrastructure remains manual: repository creation, server setup, DNS configuration, and deploy configuration are still hands-on tasks. Omaship targets the same audience but automates those infrastructure steps end to end.
Strengths
- Polished onboarding and welcome flow
- Rails 8 with clear project structure
- Cursor rules and AI-friendly conventions
- Good entry price for solo builders
Trade-offs
- No automated run execution pipeline
- No built-in CI/CD setup
- No default security scanning workflow
- Higher agency tier cost ($949)
Best for: Builders who want a polished Rails starter with guided manual setup and strong AI-assisted coding ergonomics.

shipfa.st · Next.js
ShipFast is the elephant in the room. With 8,000+ customers and Marc Lou's massive Twitter following, it dominates the "ship fast" SaaS boilerplate space. It's Next.js, not Rails—but it targets the same audience.
ShipFast excels at landing pages, SEO setup, and getting a marketing site live quickly. It includes Stripe/Lemon Squeezy payments, email integration, and auth. The community and social proof are unmatched.
Strengths
- Massive community (8,000+ customers)
- Excellent landing page templates
- Strong SEO defaults
- Marc Lou's brand and tutorials
Trade-offs
- Next.js + Vercel can mean platform lock-in
- Less suited for complex backend logic
- No security scanning or CI/CD
- "Boilerplate" more than "foundation"
Best for: Developers in the JavaScript ecosystem who want maximum social proof and great landing page templates. Less ideal if your SaaS has complex backend requirements.
What to Look for in an Agent-Built Software Foundation
Deployment, Not Just Code
Many starters give you application code and stop there. Agent-built software needs a path from "the agent changed it" to "it is live and healthy": server configuration, CI/CD, SSL, environment management, and rollback discipline.
Agent Context
Rails' convention-over-configuration philosophy gives agents a head start. Explicit context files, consistent naming, and clean architecture make the difference between an agent that can safely continue work and one that guesses.
Agent Skills
Context tells an agent what exists. Skills tell it how to create useful software from patterns that have already proven themselves: approvals, dashboards, directories, workflows, and public applications.
Solved Building Blocks
Auth, billing, teams, and other stable SaaS parts should not be reinvented for every app. Engines can handle those pieces when they fit, while the agent focuses on the custom job.
Security Defaults
Personal software can become team software or public software. Look for security scanning in CI, dependency auditing, framework-native auth, Content Security Policy headers, and secure session configuration.
Ownership Model
Decide whether you want a hosted platform, a developer template, or code and deployment infrastructure you control. For agents, ownership also means the next agent and the next human can understand what was created.
Our Recommendation
There is no single best foundation. The right choice depends on what you are asking the software to become:
- Maximum features? Jumpstart Pro
- Enterprise CRUD apps? Bullet Train
- Agent skills + deployment layer? Omaship
- Clean, minimal starting point? Sjabloon
- Paddle Billing + EU tax compliance? Business Class
- Quick MVP validation? Lightning Rails
- Pick-and-choose modules? RailKit
- Python ecosystem? SaaS Pegasus
- Guided vibe-coding flow? RailsFast
- Next.js + maximum social proof? ShipFast
Omaship is strongest when software needs to start personal, become useful for a team, and stay publishable to the world without losing the skills, engines, and foundation that keep it maintainable.
