Best Rails SaaS Boilerplates
& Starter Kits in 2026
An honest, side-by-side comparison of every serious Rails SaaS starter kit—so you can pick the right foundation and start building your product, not your infrastructure.
If you're starting a SaaS in 2026 with Ruby on Rails, you have more options than ever. Rails 8 shipped with built-in authentication, Solid Cache, Solid Queue, and Kamal—making the framework more batteries-included than at any point in its history.
But "batteries-included" still doesn't mean "SaaS-ready." You still need payments, team management, deployment pipelines, security scanning, and a dozen other things before your first customer can sign up. That's where boilerplates and starter kits come in.
We reviewed every active Rails SaaS starter kit and a notable non-Rails alternative. Full disclosure: we build Omaship, so we're obviously biased—but we've done our best to be fair. Every product here is good. The right choice depends on your priorities.

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 a Rails 8 SaaS starter kit designed for serial builders who ship multiple products. The core philosophy is "omakase"—opinionated defaults so you can focus on your product, not infrastructure decisions.
What makes Omaship different from every other option on this list is scope. It doesn't just give you application code—it includes a complete Kamal 2.0 deployment pipeline, GitHub Actions CI/CD with security scanning (Brakeman, bundler-audit), and AGENTS.md files that make the codebase immediately productive with AI coding agents like Claude Code and Cursor.
There's also a managed hosting option ($49/month) for builders who don't want to manage servers at all—unique in the Rails boilerplate space.
Strengths
- Deployment included (Kamal + CI/CD)
- AI-agent optimized (AGENTS.md, conventions)
- Security scanning in CI by default
- Managed hosting option available
- One-time purchase, you own the code
Trade-offs
- Newer product, smaller community
- Stripe-only for payments (for now)
- More opinionated = less flexibility
- No mobile (iOS/Android) templates
Best for: Solo developers and small teams who build multiple SaaS products, use AI coding tools, and want a complete "code to production" pipeline—not just application scaffolding.
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 a SaaS Starter Kit
Deployment, Not Just Code
Most starter kits give you application code and stop there. But getting from "it works on my machine" to "it's live in production" takes real work: server configuration, CI/CD pipelines, SSL, environment management. In 2026, with Kamal 2.0 making Rails deployment dramatically simpler, look for a kit that includes this.
AI-Agent Compatibility
Whether you use Claude Code, Cursor, Copilot, or another AI assistant, your codebase structure matters. Rails' convention-over-configuration philosophy already gives AI tools a head start. But explicit context files (like AGENTS.md), consistent naming, and clean architecture make the difference between an AI tool that helps and one that hallucinates.
Security Defaults
Your SaaS handles user data and payments from day one. Look for starter kits that include security scanning in CI (Brakeman for static analysis, bundler-audit for dependency vulnerabilities), rate limiting (Rack::Attack), Content Security Policy headers, and secure session configuration.
Ownership Model
Subscription models give you continuous updates but create ongoing costs. One-time purchases give you full ownership but mean you handle upgrades. Neither is objectively better—it depends on whether you value updates or independence more.
Our Recommendation
There's no single "best" Rails SaaS boilerplate. The right choice depends on what you value:
- Maximum features? Jumpstart Pro
- Enterprise CRUD apps? Bullet Train
- Code-to-production pipeline + AI tools? 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
Whatever you choose, picking any of these over building from scratch will save you weeks. The best boilerplate is the one that matches how you work.
