Deploy your Rust app to Heroku
Step-by-step deployment help for Rust apps on Heroku. We fix Rust-specific deployment issues, configure Heroku, and get your app live. From $19.
Rust issues we fix before deploying
Common Rust problems that affect Heroku deployments.
Excessive .clone() usage
AI tools clone data everywhere to satisfy the borrow checker instead of using references, lifetimes, or Cow — defeating Rust's zero-cost abstraction goals.
Unnecessary unsafe blocks
Using unsafe to bypass compiler checks rather than restructuring code to work within safe Rust, introducing memory safety vulnerabilities.
Improper error handling with unwrap()
Calling .unwrap() and .expect() on Result and Option types instead of proper error propagation with ? operator, causing panics in production.
Blocking in async contexts
Using std::thread::sleep, synchronous I/O, or blocking mutex locks inside async functions, starving the Tokio runtime of worker threads.
Heroku deployment issues we check for
Common Heroku problems that break Rust apps in production.
Free dyno sleeping causes cold starts
Eco and Basic dynos sleep after 30 minutes of inactivity. AI-generated apps with webhook receivers or background jobs break when the dyno is asleep.
Ephemeral filesystem loses uploaded files
AI tools save user uploads and generated files to the local filesystem, but Heroku's ephemeral FS wipes all changes on every dyno restart or deploy.
Database connection pool exhaustion
Heroku Postgres plans have strict connection limits (20 on Hobby). AI-generated apps open a new connection per request, exhausting the pool under moderate traffic.
Procfile missing or incorrect
AI-generated projects lack a Procfile, causing Heroku to guess the start command. For non-standard setups, this guess is often wrong.

Frequently asked questions
How do I deploy a Rust app to Heroku?
We handle Rust deployments to Heroku end to end. Start with our code audit ($19) to identify deployment blockers specific to your Rust project, then we configure Heroku, fix issues, and get your app live in production.
What Rust issues affect Heroku deployments?
Rust projects commonly have excessive .clone() usage and unnecessary unsafe blocks. On Heroku, these combine with free dyno sleeping causes cold starts and ephemeral filesystem loses uploaded files to cause deployment failures.
Can SpringCode deploy my Rust project to Heroku?
Yes. We specialize in deploying Rust applications to Heroku. We audit your codebase for Rust-specific issues, configure Heroku correctly, and handle the full deployment so your app runs reliably in production.
What does Rust deployment to Heroku cost?
Our code audit ($19) identifies all Heroku deployment blockers in your Rust project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
