High Performance

Rust and Gigalixir are a powerful combination for performance-critical applications.

Our infrastructure runs on Kubernetes, but we expose the raw performance of your binary. Because we do not impose artificial CPU throttling on standard plans, your application can fully utilize the speed and memory safety of Rust.

Small Footprint

Rust binaries are incredibly memory-efficient compared to JVM or Node.js applications.

This means you can fit significant application logic and higher concurrency into our smaller plan sizes (or even our free tier) without hitting memory limits (OOM).

No Runtime Overhead

Unlike interpreted languages, there is no garbage collector pauses or JIT warmup time.

Your application runs "close to the metal," delivering consistent throughput and predictable P99 latency from the moment it boots.

Async by Default

The runtime container is fully compatible with async runtimes like Tokio and async-std.

Whether you are building a high-performance web server with Actix or Axum, or a low-level network service, the platform supports the non-blocking I/O models Rust excels at.

FAQs

The Questions We Get The Most at Gigalixir Support

Is Rust auto-detected like Node.js or Ruby?

No.

You must add a .buildpacks file to your repository root. Inside this file, paste the URL of the buildpack you wish to use (usually https://github.com/emk/heroku-buildpack-rust).

This explicit step ensures you have full control over the build version and strategy.

Do I need to write a Dockerfile?

No.

The buildpack handles the compilation and containerization. You just push your code.

However, if you prefer to use Docker, Gigalixir does support deploying pre-built Docker images, but the buildpack route is generally faster for standard applications.

How long do builds take?

Rust compilation can be CPU-intensive and slow. However, the buildpack caches the target directory and the cargo registry between builds.

This means incremental deploys (where you only changed a few files) are significantly faster than the initial build.

How do I handle database migrations?

You can run migrations as part of your startup command in the Procfile, or use a separate "release" phase command if the buildpack supports it.

Alternatively, you can run a one-off command via the CLI: gigalixir ps:run ./target/release/my_app migrate.

Is there a free tier for Rust?

Yes.

You get 1 app instance and 1 database for free per account. Because Rust is so efficient, it is arguably the best language for maximizing the value of the free tier.

You can run a fully featured web server in the free memory allocation without performance issues.
