You built your app on Replit. The prototype works, the idea is validated, and now you need it live on a real domain with real infrastructure. This is where most Replit users hit a wall.
Replit is one of the best platforms for building and experimenting with AI-generated code. But deploying a Replit app to production with a custom domain, persistent database, and reliable uptime requires more than what Replit’s built-in deployment offers.
There are two ways to get your Replit app into production. You can deploy directly on Replit using their paid deployment options, or you can export your project to GitHub and deploy on Kuberns, where an AI agent handles your entire deployment to AWS automatically. Framework detection, environment setup, database provisioning, SSL, and custom domain are all automated in one click. No DevOps knowledge needed, no YAML files, no manual configuration.

This guide covers both paths so you can choose what works for your project.
Deploy Your Replit App in One Click Using AI Agent
This is the fastest path to getting your Replit app live on production-grade AWS infrastructure without touching a single config file.
Kuberns connects to your GitHub repository and its AI agent takes over everything from there. Here is what gets automated the moment you click deploy:
- Framework detected automatically (Node.js, Python, React, FastAPI, Django, and more)
- Build and run commands configured without manual input
- Environment variables set up securely
- Database provisioned if your app needs one
- Auto-scaling configured for traffic spikes
- SSL certificate issued and attached
- App deployed to AWS and live within minutes
No Kubernetes. No YAML. No DevOps engineer. The entire flow from code to live production URL is handled by the AI agent.
Step 1: Export Your Replit Project to GitHub
Before deploying on Kuberns, get your Replit project into a GitHub repository.
In your Replit workspace, open the Version Control tab from the left sidebar. Connect your GitHub account if you have not already, then push your project to a new repository. Replit syncs directly with GitHub, so this takes under a minute.
Once your code is on GitHub, you are ready to deploy anywhere.
Step 2: Connect Your GitHub Repo to Kuberns
Click Deploy with AI to open your Kuberns dashboard and create a new project. Select Import from GitHub, choose the repository you just pushed from Replit, and select your branch.
Kuberns reads your codebase and the AI agent immediately begins detecting your framework and configuration requirements.
Step 3: The AI Agent Handles Everything
This is where Kuberns does the heavy lifting. After connecting your repo, the AI agent:
- Identifies your framework and runtime automatically
- Sets your build command and start command
- Scans for environment variables your app needs and prompts you to fill them in
- Provisions a managed database if your app uses one
- Configures auto-scaling rules based on your app type
- Issues a free SSL certificate
You do not write a single config file. You just review what the agent detected and confirm.
Step 4: Click Deploy
Hit Deploy with AI. Your app builds and goes live on AWS infrastructure within minutes. You get a live URL immediately.

How to Add a Custom Domain to Your Replit App on Kuberns
On Kuberns, custom domain setup is a single step from your project dashboard.
Go to Domains in your project settings, enter your domain name, and Kuberns handles the rest. DNS records are configured automatically. SSL is provisioned and attached without any manual steps. Your custom domain is live within minutes of adding it.
There is no A record hunting, no TXT record copying, no waiting hours for DNS propagation while manually troubleshooting.
Developers who have gone through the full vibe coding to a live deployed app journey say the custom domain step on Kuberns is the biggest relief compared to any other platform.

Common Replit Deployment Issues (And Why Kuberns Eliminates Them)
Replit is designed as a development and prototyping environment. When you push it into production, you run into structural limitations that are not bugs. They are the result of a tool being used beyond what it was built for.
Here are the most common issues developers hit when deploying a Replit app to production, and why none of them exist on Kuberns.
App going to sleep and not staying live
Replit apps on lower tiers sleep when inactive. For a production app serving real users, this means cold starts, slow load times on first request, and a poor experience. Kuberns runs on AWS infrastructure with no sleep behaviour. Your app stays live regardless of traffic patterns.
Build failing on deploy due to environment mismatches
Replit’s local environment and its deployment environment can behave differently. Packages that work locally sometimes fail on deploy because of runtime version differences or missing system dependencies. Kuberns detects your runtime from your repo and builds in a consistent environment every time.
Database not persisting between restarts
On Replit, if you do not explicitly set up a production database during deployment, your app uses the development database. Any restart wipes local data. Kuberns provisions a managed production database automatically as part of deployment, fully separated from any development environment.
Costs scaling unexpectedly on Replit Autoscale
Replit’s Autoscale deployment charges based on actual compute usage. Under real traffic, costs can climb faster than expected without clear visibility. Kuberns pricing is transparent, and you get up to 40% savings compared to managing AWS directly, with no surprise billing.
Custom domain DNS taking hours to configure
On Replit, adding a custom domain requires manually copying A records and TXT records and pasting them into your registrar. DNS propagation can take hours, and troubleshooting failed verification is frustrating. On Kuberns, it is one click.
Most of these issues are why developers who deploy with an AI agent instead of manual platform settings never hit them in the first place.

_**Replit Deployment vs Kuberns: Which Is Right for Production?
The verdict: Replit is excellent for building and prototyping. It is where great ideas become working code fast. For production with real users, real traffic, and real uptime, Kuberns gives you AWS-grade infrastructure without the complexity, at a cost that scales sensibly.

Conclusion
Building on Replit is one of the fastest ways to go from idea to working app in 2026. The hard part, writing the code, wiring up the logic, getting something that actually works, is done.
Getting it into production with a custom domain, real AWS infrastructure, persistent database, and zero DevOps is exactly what Kuberns is built for. Connect your GitHub repo, let the AI agent handle every configuration decision, and your Replit project is live on production-grade AWS in minutes.
The number of developers going from vibe coding to a live deployed app in the same day has never been higher.
