Coolify: Deploy Anything, Anywhere, Without Vendor Lock-in

Vercel charges $200/month for 1TB bandwidth. Coolify gives you unlimited deployments on your own $5 VPS.

1. The Deployment Problem

Modern web development has a deployment problem:

Platform-as-a-Service (PaaS) providers like Vercel, Netlify, Heroku, and Railway make deployment easy:

Push to Git → automatic build → automatic deploy
SSL certificates handled
CDN included
Scaling handled

But there's a catch:

Vendor lock-in — Your app is tied to their platform
Cost at scale — $200+/month for serious traffic
Limited control — Can't customize server configuration
Data sovereignty — Your app runs on their servers

Self-hosting gives full control but requires:

Server setup and maintenance
SSL certificate management
CI/CD pipeline configuration
Monitoring and backups

Coolify bridges this gap: PaaS-like experience on your own server.

3. Technical Stack

| Component | Technology |
|-----------|-----------|
| Backend | Laravel (PHP) |
| Frontend | Livewire + Alpine.js |
| Database | PostgreSQL |
| Reverse Proxy | Caddy / Traefik |
| Containerization | Docker + Docker Compose |
| Queue | Redis |

4. Deployment

4.1 One-Command Install

# Install Coolify on any Ubuntu/Debian server
curl -fsSL https://cdn.coollabs.io/coolify/install.sh | bash

Access at http://your-server:8000

4.2 System Requirements

| Scale | CPU | RAM | Storage |
|-------|-----|-----|---------|
| Small (<10 apps) | 2 cores | 4GB | 50GB |
| Medium (10-50 apps) | 4 cores | 8GB | 200GB |
| Large (50+ apps) | 8 cores | 16GB | 500GB+ |

4.3 Adding a Server

1. Install Coolify on a fresh Ubuntu server
2. Add your server in Coolify dashboard
3. Connect Git repository (GitHub/GitLab)
4. Create application and configure:
- Build command
- Start command
- Environment variables
- Domain name
5. Deploy — Coolify handles the rest

4.4 Example: Deploy Next.js

# coolify.yaml
name: my-nextjs-app
domain: app.example.com
build:
  command: npm run build
start:
  command: npm start
env:
  - NODE_ENV=production
  - DATABASE_URL=postgresql://...

Push to main → automatic build → automatic deploy → SSL certificate → live.

5. Cost Comparison

For a typical SaaS app (5GB bandwidth, 100K requests/day):

| Solution | Monthly Cost | Annual Cost |
|----------|-------------|-------------|
| Coolify (self-hosted) | $5 VPS | $60 |
| Vercel Pro | $20 | $240 |
| Netlify Pro | $19 | $228 |
| Heroku Hobby | $7 | $84 |
| Railway | $5 | $60 |

But at scale (100GB bandwidth):

| Solution | Monthly Cost | Annual Cost |
|----------|-------------|-------------|
| Coolify | $20 VPS | $240 |
| Vercel | $200 | $2,400 |
| Netlify | $195 | $2,340 |

Annual savings at scale: $2,000+

6. Migration from Vercel/Netlify

6.1 What Transfers Easily

✅ Static sites (HTML/CSS/JS)
✅ Node.js applications
✅ Python/PHP/Go apps
✅ Custom domains
✅ Environment variables

6.2 What Needs Work

⚠️ Serverless functions → convert to API routes
⚠️ Edge functions → use Cloudflare Workers or remove
⚠️ Built-in analytics → add Plausible/Umami
⚠️ Form handling → add Formspree or custom backend

6.3 Migration Steps

1. Set up Coolify on a VPS
2. Add your Git repository
3. Configure build settings (match Vercel/Netlify)
4. Add environment variables
5. Test deployment on a subdomain
6. Update DNS to point to your server
7. Cancel Vercel/Netlify subscription

7. Use Cases

✅ Good For

Startups — Low cost, full control
Agencies — Deploy multiple client apps on one server
Developers — Escape vendor lock-in
Enterprises — Data sovereignty requirements
Side projects — Free hosting on existing VPS

Limitations

Requires server maintenance
No built-in CDN (add Cloudflare)
No serverless functions (use containers)
Smaller ecosystem than Vercel

8. Verdict

Coolify represents a growing trend: self-hostable PaaS that gives you the ease of Vercel with the control of a VPS.

What makes it significant:

Active development (weekly releases)
Strong community (20K+ GitHub stars)
Supports any application type
Regular security updates

Honest limitations:

Still maturing compared to Vercel
Documentation could be better
Some advanced features missing

Bottom line:

If you're paying $20+/month for Vercel/Netlify and have basic server skills, Coolify can save you thousands per year while giving you more control.
