Vercel Hosting and Deployment: The Complete Guide

Still searching for a modern hosting solution for your web projects? Vercel is one of the most popular deployment platforms for contemporary web applications, and it might be exactly what you need.

This article covers everything you should know about Vercel.

Why This Article?

Over the years, I’ve worked with and built many CMS platforms. I started with Contao, Typo3, and WordPress, but eventually moved on to other frameworks. Currently, I spend a lot of time with Astro and FastAPI (a Python framework).

Honestly, I don’t miss having a traditional backend anymore—at least not for static sites built like blogs or simple content platforms. The landscape has shifted significantly.

What Is Vercel?

Vercel is a cloud platform for static websites and serverless functions. Originally launched as ZEIT, it’s evolved into one of the leading deployment platforms for modern web development. The platform is particularly known for seamless Next.js integration, but it also supports many other frameworks including Astro, React, Vue, Svelte, and more.

Vercel provides:

• Automatic deployments from Git repositories
• Global Edge Network for maximum performance
• Serverless Functions for backend logic
• Preview Deployments for pull requests
• Custom domains and SSL certificates
• Analytics and performance monitoring

When Should You Use Vercel?

Vercel makes sense if you want to:

• Host static websites
• Deploy serverless applications
• Automate your CI/CD pipeline
• Guarantee global performance for your users
• Generate preview deployments for development teams
• Use Edge Functions to minimize latency
• Start for free and only pay for what you use

It’s especially well-suited for:

• Frontend developers who want rapid deployments
• Startups that need scalable infrastructure
• Agile teams deploying frequently
• Open-source projects requiring stable hosting

Who’s Already Using Vercel?

Vercel powers some of the world’s largest companies:

• Next.js – The React framework itself is hosted on Vercel
• React – The official React documentation
• Tailwind CSS – The popular CSS framework
• TypeScript – The official TypeScript website
• Vue.js – Vue.js documentation
• Svelte – The Svelte website
• Stripe – Parts of Stripe’s documentation
• Duolingo – The language-learning platform

These companies choose Vercel for its performance, reliability, and developer experience.

Installing and Setting Up Vercel

Install the Vercel CLI

The easiest way to get started is through the Vercel CLI. Install it with npm:

npm install -g vercel

Or with yarn:

yarn global add vercel

Create a Vercel Account

1. Go to vercel.com
2. Click “Sign Up”
3. Sign up using GitHub, GitLab, Bitbucket, or email
4. Verify your email address

Initialize Your Project

Navigate to your project directory and run:

vercel login

This opens a browser where you can log in to Vercel. Then:

vercel

The CLI will ask you a few questions:

• Set up and deploy? → Y
• Which scope? → Select your account
• Link to existing project? → N (for new projects)
• What’s your project’s name? → Your project name
• In which directory is your code located? → . (or your build directory)
• Want to override the settings? → N (or Y for custom settings)

Set Up Git Integration

To enable automatic deployments, connect your Git repository:

1. Go to vercel.com/dashboard
2. Click “Add New Project”
3. Import your repository from GitHub, GitLab, or Bitbucket
4. Configure your build settings
5. Click “Deploy”

From that point forward, every push triggers a new deployment.

Combining Vercel with Other Tools

Vercel and Next.js

Next.js and Vercel are a natural fit. Vercel was built by the Next.js team and offers first-class support:

// next.config.js
module.exports = {
  // Automatic optimization for Vercel
  target: 'serverless',
  // Image optimization
  images: {
    domains: ['example.com'],
  },
}

Vercel and Astro

IRC-Coding.de currently uses Astro!

Deploying Astro projects to Vercel is straightforward. I’m currently working with Coolify and Visual Studio Code:

// astro.config.mjs
import { defineConfig } from 'astro/config';

export default defineConfig({
  // Vercel adapter for serverless functions
  adapter: astro({
    output: 'server',
  }),
});

Vercel and Docker

You can also deploy Docker containers to Vercel:

# Dockerfile
FROM node:18-alpine
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
EXPOSE 3000
CMD ["npm", "start"]

Vercel and Databases

Vercel integrates with many databases:

• PostgreSQL (Neon, Supabase, PlanetScale)
• MySQL (PlanetScale)
• MongoDB (MongoDB Atlas)
• Redis (Upstash, Redis Cloud)
• Firebase (Firestore)

   • CNAME: cname.vercel-dns.com

Step 7: Configure Environment Variables

If you need environment variables:

1. Go to Settings → Environment Variables
2. Add your variables:
   • API_KEY: Your API key
   • DATABASE_URL: Your database URL
3. Save and redeploy

Step 8: Using Preview Deployments

Vercel automatically creates a preview deployment for every pull request:

1. Create a new branch:

   git checkout -b feature/neuer-artikel

2. Make changes and commit:

   git add .
   git commit -m "Neuer Artikel"
   git push origin feature/neuer-artikel

3. Open a pull request on GitHub
4. Vercel automatically creates a preview deployment
5. Test the preview before merging

Alternative: Coolify as a Self-Hosted Solution

You’ve already read about Coolify in the article—it’s an interesting alternative to Vercel. Coolify is an open-source PaaS platform that you can self-host.

Coolify vs. Vercel

Coolify (Self-Hosted):

• Pros: Full control, no monthly costs, better privacy, all data on your server
• Cons: Server administration required, no global edge network, more maintenance overhead
• Best for: Developers with server experience, projects with strict data protection requirements, budget-conscious teams

Vercel (Managed Cloud):

• Pros: No server maintenance, global edge network, automatic SSL, preview deployments, easy setup
• Cons: Monthly costs at higher traffic levels, data stored on Vercel servers, less control
• Best for: Rapid development, teams without DevOps expertise, global performance needs

Visual Studio Code: The Editor, Not the Hosting Platform

Visual Studio Code is a code editor, not a hosting solution. You can use VS Code with both:

• With Vercel: Install the Vercel Extension for direct deployments from VS Code
• With Coolify: Use VS Code for development and deploy via Git or CLI to your Coolify server

VS Code is your workspace. Choosing a hosting provider (Vercel vs. Coolify) is a separate decision.

When Should You Choose What?

Choose Vercel if:

• You want to get started quickly without server administration
• Global performance is critical
• You need preview deployments for your team
• Your budget allows for managed cloud hosting

Choose Coolify if:

• You want full control over your infrastructure
• Data protection and compliance are non-negotiable
• You have server administration skills or want to learn them
• You want to minimize long-term costs

Vercel is an excellent choice for modern web projects. The platform gives you everything you need for fast deployments, global performance, and scalable infrastructure. Especially paired with frameworks like Astro, Next.js, or React, Vercel really shines.

If you’ve never worked with Vercel before, give it a try. The free plan is generous, and you can have your first deployment live within minutes.

Good luck with your next project on Vercel!
