Built with Replit Agent? Deploy it to Heroku.
Step-by-step deployment help for Replit Agent-built apps on Heroku. We fix deployment issues, configure Heroku correctly, and get your app live in production. From $19.
Replit Agent issues we fix before deploying
Problems specific to Replit Agent's code generation that affect Heroku deployments.
Secrets stored in Replit environment
API keys and credentials stored in Replit's secrets manager don't transfer when you export the project. Developers often hardcode them as a workaround, creating security risks.
No HTTPS or security headers
Replit's development environment doesn't enforce HTTPS or set security headers. Apps deployed without proper configuration are vulnerable to man-in-the-middle attacks.
Database connection instability
Replit's hosted databases can disconnect unexpectedly. Without connection pooling and retry logic, apps crash or lose data during these interruptions.
File system assumptions
Replit Agent sometimes writes to the file system assuming persistent storage, which breaks on containerized or serverless deployments.
Heroku deployment issues we check for
Common Heroku problems that break AI-generated 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
Can you deploy a Replit Agent-built app to Heroku?
Yes. We regularly deploy Replit Agent-generated projects to Heroku. We handle the platform-specific configuration, fix deployment errors, and ensure your app runs reliably in production on Heroku.
What Heroku issues do Replit Agent projects typically have?
Replit Agent projects commonly have secrets stored in replit environment and no https or security headers. When deploying to Heroku, these combine with platform-specific issues like free dyno sleeping causes cold starts and ephemeral filesystem loses uploaded files.
How do I get my Replit Agent project live on Heroku?
Start with our code audit ($19) to get a prioritized list of deployment blockers. For Replit Agent-built projects targeting Heroku, the typical path is: fix Replit Agent-specific code issues, configure Heroku settings correctly, then deploy. We provide a fixed quote after the audit.
Can you handle the full deployment of my Replit Agent app to Heroku?
Yes. We handle end-to-end deployment: auditing your Replit Agent codebase, fixing deployment blockers, configuring Heroku correctly, setting up environment variables, and getting your app live in production. Start with our code audit ($19).
