# Ship a Durable MVP: Rails 8 With SQLite in Production and No Build Step

> A step-by-step walkthrough from an empty folder to a running app you can deploy to one $5 server — no Redis, no Node build pipeline, no PaaS. The boring stack, on purpose, with every command.

The "durable stack" idea is easy to nod along to and harder to actually run. So here it is end to end: an empty folder to a live, authenticated app on one small server, with no Redis, no Node build pipeline, and no platform-as-a-service. Every step is a command you can paste.
We're using Rails 8 because, as of mid-2026, it ships the boring, low-maintenance defaults for free — you don't have to assemble them. Current stable is **8.1.3**.
0. Prerequisites
You need Ruby (3.2+) and Docker installed locally. Then:
```
gem install rails        # installs the current stable (8.1.3)
rails --version          # => Rails 8.1.3
```
1. Generate the app
The default `rails new` already gives you SQLite, the Solid libraries, import maps, Hotwire, and Kamal. You don't need flags to get the durable stack — you'd need flags to *opt out* of it.
```
rails new blogmvp
cd blogmvp
```
What you just got, with no extra setup:
- **SQLite** as the database, tuned for production (WAL mode, immediate transactions).
- **Solid Queue / Solid Cache / Solid Cable** — background jobs, caching, and websockets, all on the database. No Redis.
- **Import maps + Hotwire** — JavaScript shipped to the browser directly. No npm, no webpack, no build step.
- **Kamal** — a `config/deploy.yml` ready for a one-command deploy.
- **Propshaft** — the modern, no-transpile asset pipeline.

2. Add real features (fast)
Scaffold a resource. This generates the model, migration, controller, views, and routes:
```
bin/rails generate scaffold Post title:string body:text published:boolean
bin/rails db:migrate
```
Run it:
```
bin/rails server
```
Open `http://localhost:3000/posts`. That's a working CRUD app — create, edit, delete, all wired — in two commands.
3. Add authentication (built in now)
Rails 8 added a first-class authentication generator. It's not a gem to configure; it scaffolds real, session-based auth you own and can edit.
```
bin/rails generate authentication
bin/rails db:migrate
```
This drops in a `User` and `Session` model, a `SessionsController`, password-reset flow (`PasswordsController` + mailer), and an `Authentication` concern you include in controllers. Add a `before_action :require_authentication` where you want to gate access, and you have login without a third-party dependency.
4. Background jobs, with no Redis
Need to send an email or process something off the request cycle? Solid Queue is already the Active Job backend. Write a normal job:
```
bin/rails generate job PublishReminder
```
```
class PublishReminderJob < ApplicationJob
  def perform(post)
    # ...runs on Solid Queue, backed by SQLite. No Redis, no Sidekiq.
  end
end
```
In development it runs inside Puma by default; in production Kamal runs the job worker for you. No separate queue service to stand up.
5. Deploy to one server
This is where the "no PaaS" claim gets real. You need a plain Linux VPS (anything — a $5–$10 box works to start) and a container registry (Docker Hub or GitHub Container Registry).
Edit `config/deploy.yml` — set your image name, the server's IP, your registry, and a domain under `proxy:` for automatic SSL:
```
service: blogmvp
image: yourname/blogmvp
servers:
  web:
    - 203.0.113.10
proxy:
  host: blog.yourdomain.com
  ssl: true
registry:
  username: yourname
  password:
    - KAMAL_REGISTRY_PASSWORD
```
Put your secrets in `.kamal/secrets`, then the first-time provision-and-deploy:
```
kamal setup
```
That builds your image, provisions the box, starts the app behind Kamal Proxy (which fetches a Let's Encrypt certificate automatically), and boots it. Every subsequent deploy is one command with zero downtime:
```
kamal deploy
```
> The whole stack — app, jobs, cache, websockets, database, TLS — runs on that one machine. No managed database, no Redis instance, no build server.

The takeaway
You now have an authenticated CRUD app with background jobs and a real deploy pipeline, running on a single cheap server, with no Redis and no JavaScript build step to maintain. That's not a toy — it's a genuinely production-shaped MVP with very few moving parts, which is exactly what makes it durable.
The honest limits, stated plainly: SQLite keeps you on one machine (a higher ceiling than most founders expect, but a ceiling), and you own that machine's patching and backups. If you already know you need Postgres, `rails new blogmvp -d postgresql` swaps only the database and leaves everything else identical.
The tool doing the deploy heavy-lifting here — Kamal — is worth understanding on its own; we cover it in a companion **[tool highlight](/posts/tool-highlight-kamal-deploy-your-own-servers.html)**. And for *why* founders are reaching for stacks like this in the first place, see **[The Durability Turn](/posts/the-durability-turn.html)**.
