## Two Opinionated Stacks

Some frameworks give you choices. **Avo** (Rails) and the **Epic Stack** (Remix) give you answers.

Both are built by experienced developers with strong opinions about how web applications should be built. **Avo** comes from the Rails tradition of convention-over-configuration — define your models, get admin panels, CRUD interfaces, and dashboards automatically. **Epic Stack** comes from Kent C. Dodds' philosophy of web standards, progressive enhancement, and testing-first development.

These are among the most opinionated starters in their respective ecosystems. If you agree with their opinions, you get massive productivity. If you disagree, you'll fight the framework.

## TL;DR

If the search is "Avo vs Epic Stack," the simplest split is this: choose **Avo** when the product is mostly internal operations, admin CRUD, dashboards, support workflows, or model-backed back offices; choose **Epic Stack** when the product is a customer-facing Remix application that needs strong testing, progressive enhancement, authentication, and TypeScript conventions from day one.

Avo ($0-$149/month, Rails/Ruby) auto-generates admin panels and CRUD interfaces from your Rails models — define a resource, get instant search, filters, actions, and dashboards. Epic Stack (free, Remix/TypeScript) is Kent C. Dodds' opinionated full-stack template with comprehensive testing, progressive enhancement, and web-standard patterns. Choose Avo for rapid admin panel and data management tool development. Choose Epic Stack for well-tested, production-grade web applications with progressive enhancement.

### Avo's Admin Generation

This is the feature that makes Avo unique. Define a resource:

```ruby
class Avo::Resources::Product < Avo::BaseResource
  self.title = :name
  self.includes = [:category, :reviews]

  def fields
    field :id, as: :id
    field :name, as: :text, required: true, sortable: true
    field :description, as: :trix
    field :price, as: :number, prefix: "$"
    field :status, as: :select, enum: ::Product.statuses
    field :category, as: :belongs_to, searchable: true
    field :reviews, as: :has_many
    field :created_at, as: :date_time, sortable: true
  end

  def filters
    filter Avo::Filters::StatusFilter
    filter Avo::Filters::PriceRangeFilter
  end

  def actions
    action Avo::Actions::PublishProduct
    action Avo::Actions::ExportCSV
  end
end
```

From this, Avo generates:
- **Index page** with sortable columns, search, and pagination
- **Show page** with formatted field display
- **Create/Edit forms** with proper input types and validation
- **Filters** for narrowing results
- **Bulk actions** for operating on multiple records
- **Association management** for related records

No HTML, no CSS, no JavaScript. The admin interface is complete and usable.

### Epic Stack's Testing Excellence

Epic Stack's testing setup is the most comprehensive of any boilerplate:

```
tests/
├── e2e/                  # Playwright end-to-end tests
│   ├── auth.test.ts
│   └── dashboard.test.ts
├── integration/          # Component + API integration
│   ├── user.test.ts
│   └── settings.test.ts
├── mocks/                # MSW request mocks
│   └── handlers.ts
└── setup/
    ├── setup-test-env.ts
    └── global-setup.ts
```

Every feature in Epic Stack comes with tests. The testing patterns are documented and repeatable:

- **Unit tests** with Vitest for utility functions
- **Integration tests** with Testing Library for components
- **E2E tests** with Playwright for user flows
- **API mocking** with MSW for reliable, fast tests
- **Database seeding** for test fixtures

Kent C. Dodds (the creator) literally wrote the book on testing JavaScript. Epic Stack is his reference implementation.

## Architecture Philosophy

### Avo (Rails): Convention-Over-Configuration

Rails decides for you:
- File names determine class names: `app/models/user.rb` → `User`
- Table names from model names: `User` → `users`
- URL patterns from controller names: `UsersController` → `/users`
- View locations from actions: `users#index` → `app/views/users/index.html.erb`

**Advantages:** Less decision fatigue, faster initial development, consistent codebases across teams.

**Disadvantages:** Fighting conventions is painful, "magic" behavior can be hard to debug, framework coupling is deep.

### Epic Stack (Remix): Web Standards

Epic Stack uses web platform APIs whenever possible:
- `<form>` elements for mutations (not client-side state)
- `Request`/`Response` objects for server communication
- HTTP `Cache-Control` headers for caching
- `Set-Cookie` for session management
- Progressive enhancement (works without JavaScript)

```typescript
// Remix loader — standard Request/Response
export async function loader({ request }: LoaderFunctionArgs) {
  const user = await requireUser(request);
  return json({ user }, {
    headers: {
      "Cache-Control": "private, max-age=60",
    },
  });
}

// Remix action — standard form submission
export async function action({ request }: ActionFunctionArgs) {
  const formData = await request.formData();
  const name = formData.get("name");
  // Validate, save, redirect
  return redirect("/dashboard");
}
```

**Advantages:** Transferable skills (web standards don't change), progressive enhancement (works offline), simpler mental model (HTTP, not framework abstractions).

**Disadvantages:** More manual work (no auto-generation), less "magic" means more code, smaller ecosystem than Next.js.

## Performance

### Server Performance

| Metric | Avo (Rails + Puma) | Epic Stack (Remix) |
|--------|-------------------|-------------------|
| Requests/sec (simple page) | ~2,000-3,000 | ~5,000-8,000 |
| Requests/sec (DB query) | ~1,000-2,000 | ~3,000-5,000 |
| Memory usage | 200-400 MB | 50-150 MB |
| Cold start | 2-5s | 0.5-1s |
| Typical TTFB | 50-100ms | 30-80ms |

Node.js/Remix is generally faster for web request handling. Ruby is slower at raw throughput but Rails' caching (Russian doll caching, fragment caching) makes production performance competitive.

### Client Performance

Epic Stack wins here significantly:
- **Progressive enhancement** means pages work without JavaScript
- **Smaller client bundles** (Remix ships less JS than a typical Rails + Turbo setup)
- **Streaming SSR** sends content as it's ready, not waiting for everything

Avo's admin panels are interactive but require Turbo and Stimulus JavaScript. For admin use cases, this is fine — admins have good connections and modern browsers.

## Community and Hiring

| Metric | Rails/Ruby | Remix/TypeScript |
|--------|-----------|-----------------|
| Language ranking (TIOBE) | ~15 | TypeScript ~8 |
| GitHub stars (framework) | 56K (Rails) | 30K (Remix) |
| Job listings | ~5,000 (Rails) | ~2,000 (Remix) |
| Stack Overflow questions | ~350K (Rails) | ~3,500 (Remix) |
| Average developer salary | High ($130K+) | High ($130K+) |
| New developers learning | Declining | Growing |

Rails has a larger established community. Remix has a growing community with overlap from the much larger React ecosystem. TypeScript developers are easier to find than Ruby developers in 2026.

## When to Choose Each

### Choose Avo (Rails) If:

- **You're building admin panels or internal tools** — Avo's auto-generation is unmatched
- **You know Ruby and love Rails** — convention-over-configuration accelerates development
- **Your app is data-management heavy** — CRUD operations on complex data models with relationships, filters, and bulk actions
- **You need background jobs natively** — Sidekiq and Active Job are production-grade
- **You want a full-stack framework** — Rails handles everything from email to WebSockets
- **You're building B2B SaaS** where the admin experience is the product

### Choose Epic Stack (Remix) If:

- **You're building customer-facing web applications** — progressive enhancement and performance matter for end users
- **Testing is important** — Epic Stack's testing setup is the gold standard
- **You value web standards** — skills transfer to any web framework
- **You want free, forever** — no licensing costs, no feature gates
- **You're hiring TypeScript developers** — larger and growing talent pool
- **Progressive enhancement matters** — forms that work without JS, HTTP caching, accessibility-first

### The Key Insight

These aren't substitutes — they're complementary approaches for different parts of an application:

- **Avo** excels at the internal/admin side where rapid CRUD generation saves weeks of development
- **Epic Stack** excels at the customer-facing side where performance, accessibility, and user experience matter

Some teams use both: Rails + Avo for the admin API and data management, a JavaScript frontend for the customer-facing application. This is a valid architecture, especially for B2B SaaS where the admin experience is complex.

---

The Rails vs Remix comparison ultimately maps to team familiarity and product requirements more than framework superiority. Rails + Avo is the faster path to a complex admin interface; Remix + Epic Stack is the better-tested, better-documented path to a full-stack product with high-quality user-facing UI. Teams that have shipped Rails applications and are extending them with admin tooling should reach for Avo. Teams building new products and choosing a full-stack framework for the first time should evaluate Epic Stack alongside Next.js alternatives.
