ShipFast vs Epic Stack: Next.js vs Remix Boilerplates Compared
TL;DR
ShipFast ($199, Next.js) and Epic Stack (free, Remix/React Router) represent two fundamentally different philosophies for starting a web application. ShipFast is a paid boilerplate optimized for speed to market — auth, payments, email, and a landing page wired up so you can ship a product this weekend. Epic Stack is a free, open-source reference architecture optimized for correctness — comprehensive testing, progressive enhancement, and production-grade infrastructure so your application works properly from day one. The choice is less about features and more about what you believe software should be.
Key Takeaways
- Price is not the real difference. ShipFast costs $199. Epic Stack is free. But the meaningful gap is in philosophy, not pricing — you are choosing between speed-to-revenue and engineering rigor.
- Framework choice has downstream consequences. ShipFast uses Next.js with the App Router. Epic Stack uses Remix (now React Router 7). This affects how you handle data loading, form submissions, error boundaries, and progressive enhancement.
- Testing is the sharpest divide. Epic Stack ships with Vitest for unit tests, Playwright for end-to-end tests, Testing Library for component tests, and MSW for API mocking — all pre-configured and wired into CI. ShipFast has no testing setup out of the box.
- Deployment assumptions differ. ShipFast is optimized for Vercel's serverless model. Epic Stack is built around Fly.io with Docker, LiteFS for distributed SQLite, and multi-region replication.
- Database philosophy splits clearly. ShipFast offers MongoDB or Supabase (PostgreSQL). Epic Stack uses SQLite with Prisma ORM and LiteFS — a deliberately unconventional choice that co-locates data with compute for lower latency.
- Community culture matters. ShipFast has 5,000+ makers on Discord focused on shipping and revenue. Epic Stack's community centers on Kent C. Dodds' educational ecosystem, Epic Web Dev, which prioritizes learning and best practices.

Framework Philosophy: The Core Divide
The most important difference between ShipFast and Epic Stack is not a feature — it is a belief about how web applications should work.
ShipFast and Next.js
ShipFast builds on Next.js with the App Router, which means React Server Components, server actions, and streaming. Data fetching happens in server components using async/await. Mutations use server actions or API routes. The mental model is React-first: everything is a component, even your server-side logic.
ShipFast ships both App Router and Pages Router codebases in JavaScript and TypeScript variants. The code is structured for readability and AI-assisted development — flat directories, clear naming, minimal abstraction. The deployment story assumes Vercel, which is a reasonable trade-off given Vercel's generous free tier and unmatched deploy experience.
Epic Stack and Remix
Epic Stack builds on Remix (now React Router 7), and the philosophy difference is visible in every file. Data loading uses loader functions that run on the server. Mutations use action functions that process form submissions. This is not just a different API — it is a different relationship with the web platform.
Remix's model is built around progressive enhancement. Forms work without JavaScript. Navigation works without client-side routing. Error boundaries catch failures at the route level without crashing the entire page. The Epic Stack leans into this fully — its forms use Conform for progressive enhancement with full type safety, meaning your application remains functional even when JavaScript fails to load.
This is not an academic concern. On unreliable mobile connections or when a third-party script blocks the main thread, progressive enhancement is the difference between a working application and a white screen.
The trade-off is ecosystem size. Next.js has a larger community, more tutorials, and broader industry adoption. Finding a Next.js developer is easier than finding a Remix developer.
Authentication: Convenience vs. Completeness
ShipFast
ShipFast uses NextAuth.js with two pre-configured providers: Google OAuth and magic link (passwordless email). This covers the two most common authentication flows for consumer applications. The integration is clean, well-documented in the Next.js ecosystem, and works out of the box.
What you do not get: password-based login, multi-factor authentication, account linking between providers, or granular permissions. If you need any of these, you are either extending NextAuth yourself or replacing it entirely.
Epic Stack
Epic Stack implements authentication from scratch rather than relying on a third-party library. The system includes email/password login with secure password hashing, third-party OAuth (GitHub by default, extensible to others), TOTP-based two-factor authentication using the @epic-web/totp library, email verification flows, password reset with time-limited tokens, and session management with cookie-based sessions.
The stack also includes a role-based access control (RBAC) system with a permissions model defined in Prisma. Roles and permissions are seeded into the database and checked at the route level, giving you fine-grained control over who can access what.
This is significantly more authentication infrastructure than ShipFast provides. The trade-off is complexity — the Epic Stack's auth system spans multiple files, database tables, and middleware layers. Understanding and customizing it requires more time than configuring NextAuth providers.
Testing: The Sharpest Divide
This is where the philosophical difference becomes most concrete.
ShipFast: Testing Is Your Problem
ShipFast includes no testing setup. No test runner, no test files, no CI configuration, no mocking utilities. The assumption is that solo founders validating ideas do not need tests — they need to ship, get feedback, and iterate.
This is a defensible position for MVPs. Writing tests for a product that might pivot next week is arguably wasted effort. But if your product finds traction and you need to add features without breaking existing functionality, you are starting from zero.
Epic Stack: Testing Is the Foundation
Epic Stack treats testing as infrastructure, not overhead. The stack includes:
- Vitest for unit and integration tests, configured with path aliases and environment setup matching the application
- Testing Library for component-level tests that verify behavior rather than implementation details
- Playwright for end-to-end tests that exercise full user flows (signup, login, content creation, profile management) in a real browser
- MSW (Mock Service Worker) for intercepting network requests in tests without coupling to implementation
- A dedicated test database so tests run against real SQLite with Prisma migrations, not mocked data
- GitHub Actions CI that runs the full test suite on every pull request
Kent C. Dodds is the author of Testing Library and one of the most influential voices in JavaScript testing. The Epic Stack reflects years of thinking about what testing should look like in a modern web application. Every pattern — from how tests access the database to how authentication is handled in E2E flows — is intentionally designed.
If you believe that untested code is a liability, Epic Stack gives you a head start that would take one to two weeks to build yourself.
Database and Data Layer
ShipFast: Flexible and Familiar
ShipFast supports MongoDB and Supabase (PostgreSQL) as database options, both pre-configured with schemas, environment setup, and connection handling. MongoDB is the default, reflecting the document-database preference common in the Node.js ecosystem. Supabase integration was added more recently and requires the App Router version.
The choice of MongoDB is pragmatic for rapid prototyping — flexible schemas let you iterate on your data model without writing migrations. For simple SaaS products with straightforward data relationships, this works well. For applications with complex relational data, you may find yourself fighting MongoDB's document model.
Epic Stack: SQLite, Seriously
Epic Stack's most controversial technical decision is using SQLite as its production database. Not PostgreSQL. Not MySQL. SQLite — the embedded database that most developers associate with mobile apps and prototypes.
The reasoning is deliberate. SQLite runs on the same machine as your application, eliminating network latency for database queries. Combined with Fly.io's multi-region deployment and LiteFS (a distributed filesystem for SQLite), this gives you a globally replicated database with single-digit millisecond reads at every edge location.
Prisma provides the ORM layer with type-safe queries, migrations, and seeding. The schema is well-structured with models for users, sessions, permissions, roles, notes (as the example domain), and images.
The trade-off is real. SQLite has write throughput limitations in high-concurrency scenarios. If your application needs to handle thousands of concurrent writes, PostgreSQL is the better choice. For read-heavy applications — which most web apps are — SQLite's performance is surprisingly competitive, and the operational simplicity of not managing a separate database server is significant.
Deployment: Vercel vs. Fly.io
ShipFast assumes Vercel. Push to GitHub, connect to Vercel, and your application is live with automatic preview deploys, edge functions, and a global CDN. The lock-in is real but manageable — moving a Next.js app off Vercel requires reworking middleware and environment variable patterns, but it is possible.
Epic Stack deploys to Fly.io using Docker containers with a pre-configured Dockerfile, fly.toml, and GitHub Actions for automated deployment to staging and production. The infrastructure is more complex but fully portable — Docker means you can deploy to AWS ECS, Google Cloud Run, or your own hardware. The stack also includes Sentry for error tracking and Grafana dashboards for monitoring, which ShipFast leaves entirely to you.
Payments: Included vs. BYO
ShipFast ships with Stripe and Lemon Squeezy integration — checkout flows, webhook handlers, subscription management, and customer portal links. For a standard SaaS with tiered pricing, this saves several days of Stripe documentation reading and webhook debugging.
Epic Stack does not include payment integration. It is a reference architecture for building web applications, not a SaaS template. Adding Stripe yourself is straightforward (Remix's action-based form handling maps cleanly to payment flows), but you are writing the integration from scratch.
This is the clearest case where ShipFast saves you time. If your product charges money — and it should — ShipFast's payment integration is worth the $199 on its own.
Code Quality and Maintenance
ShipFast's codebase prioritizes readability over rigidity. Both JavaScript and TypeScript are supported. The directory structure is flat and feature-organized. AI coding tools work well with the patterns because they are simple and predictable. Marc Lou maintains multiple products, so updates to ShipFast are periodic rather than continuous.
Epic Stack enforces strict TypeScript, ESLint with comprehensive rules, Prettier for formatting, and Zod for runtime validation. The CI pipeline catches type errors, lint violations, and test failures before code reaches the main branch. The project is open source and accepts community contributions. Architectural decisions are documented in a docs/decisions/ directory that explains the reasoning behind every major choice — a level of transparency rare in starter templates.
How to Choose
Choose ShipFast if:
- You need to launch this weekend. Auth, payments, email, landing page, and deployment are wired up. Add your business logic and ship.
- You are building a solo B2C product — individual user accounts, simple pricing, no team features.
- Revenue validation is the priority. You want to find out whether people will pay before investing in architecture.
- You want Next.js. Your team knows React and Next.js, and you want to stay in that ecosystem.
- Payment integration matters most. Stripe and Lemon Squeezy out of the box is the single biggest time savings ShipFast offers.
- Community and marketing matter. 5,000+ makers on Discord, launch feedback, and a revenue leaderboard create accountability.
Best for: MVPs, indie hacker projects, AI wrappers, micro-SaaS tools. Estimated time to first deploy: 1-3 days.
Choose Epic Stack if:
- You value correctness over speed. You would rather spend a week setting up properly than a month fixing shortcuts.
- Testing is non-negotiable. You want Vitest, Playwright, Testing Library, and MSW configured and ready to use.
- You prefer web standards and progressive enhancement. Your application should work when JavaScript fails, forms should submit without client-side code, and navigation should use the platform.
- You want to learn best practices. The Epic Stack is as much a teaching tool as a starter template. The decision documents explain why every choice was made.
- You are comfortable without payments and marketing pages. You will add Stripe yourself. You will build your own landing page. You are paying with time, not money.
- Fly.io's deployment model appeals to you. Docker containers, multi-region SQLite, and no serverless vendor lock-in.
- Budget is zero. Epic Stack is free and open source.
Best for: Products where reliability matters, applications serving users on unreliable connections, teams that value testing and code quality, developers who want to learn from a well-architected codebase. Estimated time to first deploy: 1-2 weeks.
