Deploy your Astro app to Heroku
Step-by-step deployment help for Astro apps on Heroku. We fix Astro-specific deployment issues, configure Heroku, and get your app live. From $19.
Astro issues we fix before deploying
Common Astro problems that affect Heroku deployments.
Unnecessary client directives
Using client:load on components that don't need interactivity, shipping JavaScript that negates Astro's zero-JS advantage.
Misconfigured SSR adapters
Server-side rendering adapter not properly configured for the deployment target, causing build failures or runtime errors in production.
Island hydration mismatches
React, Vue, or Svelte islands that fail to hydrate correctly due to server/client rendering differences, causing layout shifts and broken interactions.
Missing image optimization
Using raw <img> tags instead of Astro's built-in <Image> component, serving unoptimized images that slow page loads.
Heroku deployment issues we check for
Common Heroku problems that break Astro 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 Astro app to Heroku?
We handle Astro deployments to Heroku end to end. Start with our code audit ($19) to identify deployment blockers specific to your Astro project, then we configure Heroku, fix issues, and get your app live in production.
What Astro issues affect Heroku deployments?
Astro projects commonly have unnecessary client directives and misconfigured ssr adapters. 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 Astro project to Heroku?
Yes. We specialize in deploying Astro applications to Heroku. We audit your codebase for Astro-specific issues, configure Heroku correctly, and handle the full deployment so your app runs reliably in production.
What does Astro deployment to Heroku cost?
Our code audit ($19) identifies all Heroku deployment blockers in your Astro project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
