Welcome to Loco!

Loco is "Rust on Rails".

Loco is strongly inspired by Rails. If you know Rails and Rust, you'll feel at home. If you only know Rails and new to Rust, you'll find Loco refreshing. We do not assume you know Rails.

To work with Loco, you need to know Rust to a beginner-moderate level. There are no crazy lifetime twisters and most of the development will be linear: request handling, workers, tasks, etc.

Quick Start

$ cargo install loco-cli

Now you can create your new app (choose "Saas app").

$ loco new
❯ App name? [myapp]:
❯ Saas app (with DB and user auth)
  Stateless service (minimal, no db)
🚂 Loco app generated successfully in:
myapp

When generating a starter, the database name incorporates your application name and the environment. For instance, if you include myapp, the database name in the test.yamlconfiguration will be myapp_test, and in the development.yaml configuration, it will be myapp_development.

$ docker run -d -p 5432:5432 -e POSTGRES_USER=loco -e POSTGRES_DB=myapp_development -e POSTGRES_PASSWORD="loco" postgres:15.3-alpine

Now cd into your myapp and start your app:

$ cd myapp
$ cargo loco start
Finished dev [unoptimized + debuginfo] target(s) in 21.63s
    Running `target/debug/myapp start`

Project Status

Loco is feature complete, but features are still being added rapidly.

What can you build?

• Stateless APIs
• Complete SaaS products with user authentication
• Purpose-built services such as ML inference endpoints
• Full stack projects with separate frontend project integrated with Loco
• Hobby projects full-stack with backend and HTML frontend

What's being done now?

• View issues for what we plan next and what we work on (you're welcome to submit PRs!)
• View CHANGELOG for what we already added
