Shuttle - Deploy Rust apps with a single Cargo subcommand

Hello, and welcome to the shuttle API documentation!

Shuttle is an open-source app platform that uses traits and annotations to configure your backend deployments.


Depend on shuttle-service in Cargo.toml:

shuttle-service = "0.2"

and make sure your crate has a cdylib output target:

crate-type = ["cdylib"]

See the shuttle_service::main macro for more information on how to implement a service. Here’s a simple example using [rocket][rocket] to get you started:

extern crate rocket;

use rocket::{Build, Rocket};

fn hello() -> &'static str {
    "Hello, world!"

async fn init() -> Result<Rocket<Build>, shuttle_service::Error> {
    let rocket = rocket::build().mount("/", routes![hello]);


Complete examples can be found in the repository.


You can deploy your service with the cargo shuttle subcommand. To install run:

$ cargo install cargo-shuttle

in a terminal. Once installed, run:

$ cargo shuttle login

this will open a browser window and prompt you to connect using your GitHub account.

Then, deploy the service with:

$ cargo shuttle deploy

Your service will immediately be available at {crate_name}.shuttleapp.rs. For example:

$ curl https://hello-world-rocket-app.shuttleapp.rs
Hello, world!

Using sqlx

Here is a quick example to deploy a service which uses a postgres database and sqlx:

extern crate rocket;

use rocket::{Build, Rocket};
use sqlx::PgPool;

struct MyState(PgPool);

fn hello(state: &State<MyState>) -> &'static str {
    // Do things with `state.0`...
    "Hello, Postgres!"

async fn rocket(pool: PgPool) -> Result<Rocket<Build>, shuttle_service::Error> {
    let state = MyState(pool);
    let rocket = rocket::build().manage(state).mount("/", routes![hello]);


To learn more about shuttle managed services, see shuttle_service::main.


The cargo shuttle command can be customised by creating a Shuttle.toml in the same location as your Cargo.toml.

Getting API keys

After you’ve installed the cargo-shuttle command, run:

$ cargo shuttle login

this will open a browser window and prompt you to connect using your GitHub account.

Change the name of your service

To have your service deployed with a different name, add a name entry in the Shuttle.toml:

name = "hello-world"

If the name key is not specified, the service’s name will be the same as the crate’s name.

We’re in alpha 🤗

Thanks for using shuttle! We’re very happy to have you with us!

During our alpha period, API keys are completely free and you can deploy as many services as you want.

Just keep in mind that there may be some kinks that require us to take all deployments down once in a while. In certain circumstances we may also have to delete all the data associated with those deployments.

pub use error::Error;


Types representing various errors that can occur in the process of building and deploying a service.


Helper macro that generates the entrypoint required of any service.


A wrapper that takes a user’s future, gives the future a factory, and takes the returned service from the future The returned service will be deployed by shuttle


Factories can be used to request the provisioning of additional resources (like databases).

Used to get resources of type T from factories.

A convenience trait for handling out of the box conversions into Service instances.

The core trait of the shuttle platform. Every crate deployed to shuttle needs to implement this trait.

Type Definitions

Attribute Macros

Helper macro that generates the entrypoint required by any service - likely the only macro you need in this crate.
