Compiled Speed, Managed Convenience
Deploy Rust binaries with git push. Scale with gigalixir ps:scale.
Get the raw performance of machine code with the convenience of a PaaS. No multi-stage Dockerfiles required.
Deploying Rust often involves writing complex multi-stage Dockerfiles to keep image sizes down and managing registry credentials. Gigalixir simplifies this by handling the compilation pipeline for you.
You provide the source code, and our build infrastructure compiles the binary and packages it into a lightweight runtime container. You get a production-ready artifact without managing the build environment or base images yourself.
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.
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).
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.
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.
Build robust backends with direct access to managed storage.
We provide the network conditions required for modern Rust database tools to function correctly, removing the middleware that often causes compatibility issues.
The Questions We Get The Most at Gigalixir Support
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.
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.
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.
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.
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.
