You have built a SvelteKit app. It runs perfectly on localhost. Now you need it live in production, with HTTPS, environment variables wired correctly, and deployments that trigger automatically on every git push.

If you have tried the manual route before, you know the overhead. A Linux server, Node.js installed on it, PM2 to keep the process alive, Nginx configured as a reverse proxy, Certbot fighting you over SSL, and a CI/CD pipeline stitched together from GitHub Actions YAML. That gap between working locally and running in production can swallow an entire day before anything is actually live.

This guide covers the fastest path from your SvelteKit app to a live production URL on [Kuberns](https://kuberns.com), the world's first Agentic AI deployment platform. No server setup. No Dockerfile. No YAML.

## Prerequisites: Prepare Your SvelteKit App for Production

These two steps take less than five minutes and prevent the most common deployment failures.

### 1. Bind to process.env.PORT

This is the most common reason SvelteKit apps fail silently in the cloud. Every deployment platform injects a dynamic port via the `PORT` environment variable. SvelteKit's `adapter-node` already respects this automatically, but if you have a custom server entry, make sure it reads `process.env.PORT`.

For a standard SvelteKit project with no custom server, you are already covered. No changes needed.

### 2. Confirm Your package.json Scripts

Kuberns AI reads your `scripts` block to determine the build and start commands. Your `package.json` should have these:

```json
{
  "scripts": {
    "build": "vite build",
    "start": "node build",
    "dev": "vite dev"
  },
  "engines": {
    "node": ">=20.0.0"
  }
}
```

The `build` and `start` scripts are all Kuberns needs. No Procfile. No Dockerfile. No extra config.

### 3. Push Your Code to GitHub

Kuberns deploys directly from your repository. If your project is not on GitHub yet:

```bash
git init
git add .
git commit -m "Initial SvelteKit app"
git branch -M main
git remote add origin https://github.com/yourusername/your-sveltekit-app.git
git push -u origin main
```

That is the complete prerequisite list. No Docker image, no YAML config, no CLI tools to install.

## Step-by-Step: Deploy SvelteKit on Kuberns

[Kuberns](https://kuberns.com) is an Agentic AI cloud platform built on AWS. It auto-detects your SvelteKit framework, runs the build, starts your app, handles SSL, and manages auto-scaling without any configuration from you.

### Step 1: Sign Up and Create an Account
![kuberns-home](https://kuberns-blogs-media.s3.ap-south-1.amazonaws.com/kuberns-homepage.png)
Go to [kuberns.com](https://kuberns.com) and click "Deploy with AI". Create a new account by signing in with Google or GitHub. New accounts receive free credits to deploy and test your app without a credit card.

### Step 2: Connect Your GitHub Repository

On the "Create Service" page, connect your GitHub account and select your SvelteKit repository and branch.

![Connect GitHub to Kuberns](https://kuberns-blogs-media.s3.ap-south-1.amazonaws.com/kuberns-registration.png)

Kuberns AI scans your project and detects:
- Framework: SvelteKit
- Build command: `npm run build`
- Start command: `node build`
- Node.js version from the `engines` field

No framework dropdown. No runtime version picker. No start command to write. The AI reads what you have written and configures everything accordingly.

> "On other platforms you would need to specify build commands, runtime versions, and start commands in a separate config file. On Kuberns, the AI infers all of it from your project."

### Step 3: Add Environment Variables

Go to the Environment tab and add your app secrets.

![Environment variables on Kuberns](https://kuberns-blogs-media.s3.ap-south-1.amazonaws.com/environment-variable-kuberns.png)

SvelteKit uses two types of environment variables:

- `PUBLIC_*` - safe to expose to the browser, accessible via `$env/static/public`
- Everything else - server-only secrets, accessible via `$env/dynamic/private`, never sent to the client

For a typical SvelteKit app, add variables like:

```
PUBLIC_API_URL=https://api.yoursite.com
DATABASE_URL=postgresql://...
SESSION_SECRET=your_secret_here
NODE_ENV=production
```

You can add them one by one or upload your `.env` file directly. Kuberns encrypts every variable and injects them securely at runtime. Never commit secrets to your repository.

### Step 4: Click Deploy, Let the AI Take Over

Click Deploy and watch the real-time logs as Kuberns Agentic AI takes over:

![Kuberns AI deploying SvelteKit app](https://kuberns-blogs-media.s3.ap-south-1.amazonaws.com/agent-deployment-process.png)

- Installs all packages from `package.json`
- Runs `npm run build` to compile your SvelteKit app
- Provisions AWS compute in your chosen region
- Issues and configures an SSL certificate
- Assigns a live HTTPS URL to your application
- Sets up CI/CD - every push to your connected branch triggers an automatic redeploy

Your SvelteKit app is live within minutes.

## Deploying SvelteKit with a Database

Most SvelteKit apps connect to a database for server-side load functions and API routes. Here is what to handle for a production deployment.

### Use Environment Variables for All Database Config

Never hardcode credentials. Access them via `$env/dynamic/private` in your server-side code:

```typescript
// src/lib/server/db.ts
import { DATABASE_URL } from '$env/dynamic/private';
import { Pool } from 'pg';

const pool = new Pool({
  connectionString: DATABASE_URL,
  ssl: process.env.NODE_ENV === 'production'
    ? { rejectUnauthorized: false }
    : false,
});

export default pool;
```

Set `ssl: { rejectUnauthorized: false }` when connecting to managed databases like AWS RDS, Supabase, or Neon.

### Add DATABASE_URL to Kuberns

In the Kuberns dashboard Environment tab, add your `DATABASE_URL`. The format for PostgreSQL is:

```
postgresql://username:password@host:5432/database_name
```

Kuberns injects it securely at runtime. Your SvelteKit server-side code reads it via `$env/dynamic/private`.

## What Kuberns Handles That You Would Otherwise Do Manually

| What SvelteKit needs in production | Manual / VPS | Kuberns |
|---|---|---|
| Framework and adapter detection | Manual svelte.config.js setup | AI detects automatically |
| Process manager | Install and configure PM2 | Not needed |
| Nginx reverse proxy | Manual config | Not required |
| SSL certificate | Certbot setup and renewal | Automatic |
| Environment variables | Server env files | Encrypted in dashboard |
| Auto-scaling | Manual rules | AI-driven |
| CI/CD pipeline | GitHub Actions YAML | Built-in, triggers on git push |
| Custom domain + HTTPS | DNS config + Certbot | One-click in dashboard |
| Crash recovery | PM2 ecosystem config | Automatic |
| Monitoring and logs | Prometheus / Datadog setup | Built-in, zero setup |

## Why Teams Deploy SvelteKit on Kuberns

Kuberns is not just a hosting platform. It is an Agentic AI that manages your entire deployment lifecycle, from the first deploy to scaling under traffic spikes, without you writing a single config file.

- Agentic AI deployment that auto-detects SvelteKit and builds without any configuration
- Automatic HTTPS with TLS certificates provisioned and renewed without manual steps
- Zero cold starts so your app stays responsive under any traffic pattern
- Autoscaling that adjusts resources in real time based on actual load
- Unified monitoring with logs, metrics, and alerts in one place, no Grafana setup required
- Git-push deploys where every push to main redeploys in under 2 minutes with zero downtime
- No DevOps team required. One developer can manage a production SvelteKit app confidently
