You just built something real with Lovable. The UI works, the flows are smooth, and you are ready to put it in front of actual users. The fastest way to get there is Kuberns: connect your GitHub repository, click deploy, and your Lovable app is live with HTTPS and a custom domain in under 5 minutes. No YAML. No DevOps. No infrastructure configuration.
But before you hit that deploy button, there is a gap most builders miss. The yourapp.lovable.app URL you have been sharing is a preview environment, not a production deployment. It is optimised for speed and testing, not for real traffic, real data, or real security. Closing that gap is exactly what this guide covers.
Whether you built a SaaS app, an internal tool, or a client-facing product, the path from Lovable prototype to a live production URL follows the same steps. This guide walks you through all of them.
What Lovable Gives You (and What It Does Not)
Lovable is genuinely impressive at what it does. You describe what you want, and it builds a working app with authentication, a database via Supabase, and a deployable frontend. That is a remarkable amount of work handled automatically.
The built-in hosting is just as convenient. Every Lovable project gets a yourapp.lovable.app URL the moment you publish. For sharing prototypes and getting early feedback, that is more than enough.
The problem starts when you need more. Lovable’s built-in hosting is built for previews, not production. It does not provide:
- Autoscaling when traffic spikes
- Persistent backend infrastructure beyond Supabase
- Production-grade environment variable security
- Custom domains on the free plan
- SLA-backed uptime
You also own your code. Lovable lets you export your full project to a GitHub repository with one click, which means you are not locked into their infrastructure. That GitHub connection is the bridge to a real production deployment, using the same auto-deploy from GitHub in one click that powers every Kuberns project.
Think of Lovable as where you build. Production is where your users live. They are different environments with different requirements, and the yourapp.lovable.app URL sits firmly in the first category.

Before You Deploy, Check These 3 Things First
Skipping this section is how Lovable apps end up with exposed user data in production. Take 15 minutes here before anything else.
Lock Down Supabase Row Level Security
This is the single most important step before going live. By default, Supabase tables have Row Level Security disabled. That means anyone with your Supabase URL and anon key can read, write, and delete any data in your database.
Your anon key is exposed in client-side code. It is designed to be public. The only thing protecting your data is RLS.
A 2025 security audit found that 170 out of 1,645 Lovable apps had live security vulnerabilities, with missing or misconfigured RLS as the most common cause.
Enable RLS on every table that contains user data. No exceptions. Go to your Supabase dashboard, open each table, and toggle Row Level Security on. Then add policies that define who can read or write each row. If you are not sure what policies to add, open Lovable and ask it to write RLS policies for each table. It will handle it.
Move Secrets Out of Client Side Code
Lovable sometimes generates code that handles sensitive operations from the browser. That is a problem, because anything running in a browser can be inspected and replayed by any user.
Two categories matter here:
Safe to expose client-side (use VITE_ prefix): Supabase URL, Supabase anon key, Stripe publishable key, analytics keys.
Must never be in client-side code: Supabase service role key, Stripe secret key, OpenAI API keys, database connection strings, webhook secrets.
Search your codebase for any of these before deploying. If you find them, move them to server-side functions or Supabase Edge Functions immediately.
Set Your Environment Variables Correctly
Lovable apps use two types of environment variables. Build-time variables are injected during the build process and baked into the compiled output. Runtime variables are injected when the app is running.
For Supabase specifically, VITE_SUPABASE_URL and VITE_SUPABASE_ANON_KEY are build-time variables. If you are unsure about any variable, ask Lovable directly: it will tell you whether it needs to be available at build time or runtime. Set them once in the Kuberns dashboard and they are applied consistently on every deploy, no manual intervention needed.
Get Your Lovable App Live With Kuberns AI In One Click
Once your security checklist is done, deployment itself takes under 5 minutes. Kuberns is an agentic AI deployment platform built on AWS. It detects your framework, configures the build, provisions infrastructure, and gets your app live without any manual configuration.
No YAML. No Dockerfiles. No DevOps knowledge required. Trusted by 3,000+ builders.
Here is the exact process:
Step 1: Export your Lovable project to GitHub
In the Lovable editor, click the GitHub button in the top navigation bar. Connect your GitHub account and select or create a repository. Lovable syncs your project to the repository and keeps it in sync automatically as you make changes.
Before exporting, add a start script to your package.json. Open the Lovable chat and paste this prompt:
**_
Add a start script to package.json that serves the build output on port 3000 using the serve package.
_**
Lovable will make the change. Confirm it looks applied in the editor before moving on.
Step 2: Connect your repository to Kuberns
Go to Kuberns dashboard and create a new project. Connect your GitHub account, select the repository you just synced from Lovable, and choose the branch to deploy from. Kuberns auto-detects your framework and configures the build automatically.
Step 3: Add your environment variables
In the Kuberns dashboard, add your environment variables under the project settings. For Supabase, add VITE_SUPABASE_URL and VITE_SUPABASE_ANON_KEY as build-time variables. Any runtime secrets go in the runtime section. Set them once; Kuberns applies them on every deploy.
Step 4: Click deploy
That is it. Kuberns builds your app, provisions TLS, and gives you a live URL in under 5 minutes. Auto-redeployment is on by default, so every future change you make in Lovable syncs to GitHub and goes live automatically.
Pricing starts at $7, which unlocks $14 of credits, enough to run your app for a full 30 days. Plans scale from there: Starter at $10/month, Basic at $15/month, Standard at $20/month, and higher tiers for growing apps. No per-user pricing. No hidden fees. Pay only for active resources. Every plan comes with a 100% moneyback guarantee.
Connect a Custom Domain on Kuberns
A production app needs a real domain, not a generated subdomain. In the Kuberns dashboard, go to your project settings and add your custom domain. Kuberns provides a CNAME record to add to your DNS provider. Once the DNS propagates, SSL is provisioned automatically.
One step most builders miss: after switching to a custom domain, update your Supabase project’s Site URL under Authentication settings, and update any OAuth redirect URLs to point to the new domain. If you skip this, users will not be able to log in after the domain switch.

How Kuberns Compares to Other Lovable Hosting Options
Every major deployment platform can technically host a Lovable app. The difference is in how much work you have to do yourself, and how well the platform handles full-stack apps as they grow.
Vercel and Netlify work well for pure frontend Lovable apps, but both have limitations when your app needs persistent backend services or a full-stack deployment. Northflank is a solid choice for teams that need Kubernetes-level infrastructure control, but the setup complexity is significantly higher.
Kuberns is the only option in this list that combines one-click AI deployment, full-stack support, and pricing that starts at $7 with no per-user charges. For a solo builder or small team deploying a Lovable app, it is the most direct path from repository to live production URL.

Common Lovable Deployment Issues (How Kuberns Fixes Each One)
These are the five issues that catch most builders after they export from Lovable. Each one has a specific cause and a specific fix.
App works in preview but breaks after deploy
The most common cause is environment variables not being available during the build. In Lovable’s preview, variables are injected automatically. In a self-managed deployment, you have to set them explicitly. On Kuberns, you set them once in the dashboard and they are injected at both build time and runtime correctly, based on the variable type. No manual configuration needed.
Environment variables not loading
Related to the above, but specifically happens when build-time variables like VITE_SUPABASE_URL are added as runtime variables or vice versa. Kuberns separates build-time and runtime variables clearly in the dashboard, eliminating this confusion.
Auth redirects going to the wrong domain
After you connect a custom domain, Supabase still has the old yourapp.lovable.app URL configured as the redirect target. Update the Site URL and OAuth redirect URLs in your Supabase project under Authentication settings. On Kuberns, your custom domain is persistent and tied to the deployment, so it never changes unexpectedly.
Build fails after GitHub export
This usually happens because the repository is missing a start script or the framework is not detected correctly. Kuberns auto-detects Next.js, React, Vue, and other common Lovable output frameworks. If the build fails, the dashboard shows the exact error log so you can fix it without guessing.

If your app broke right after going live, you are not alone. Here is why AI-built apps break in production and how to fix each issue.

App goes down under real traffic
Lovable’s built-in hosting is not built for traffic spikes. Kuberns runs on AWS with autoscaling included. When traffic grows, your app scales with it automatically, without any manual intervention or infrastructure changes.
**_
Deployment failures are more common than most builders expect. Here is why software deployments fail and what you can do to prevent it.

Conclusion
In 2026, you should not be spending hours configuring servers, writing Dockerfiles, or debugging build pipelines just to get a Lovable app in front of real users. The building is done. The deployment should be equally fast.
Kuberns is the deployment layer the vibe coding ecosystem has been missing. It is built specifically for developers who want to go from a working app to a live production URL without switching contexts into DevOps work. Connect your GitHub repo, set your environment variables, click deploy. Done.
Whether you built with Lovable, Bolt, Cursor, or Windsurf, the last step is always the same. This is what vibe deployment actually means in 2026 and why teams are moving to it fast.
If you are still in the build phase, these vibe coding best practices will save you debugging time before you even hit deploy.
