How Does Vercel Work?

Here is each stage of the process, from local development to delivery to the end user:

1. Local Development with Modern Tools

You work on your local machine using your favorite code editor and frameworks like Next.js, React, or Vue.js. Vercel provides a CLI (Command Line Interface) that lets you test your application locally in an environment similar to production, ensuring everything works correctly before pushing your code.

2. Code Repository Integration

You connect your project to Vercel by linking your repository on GitHub, GitLab, or Bitbucket. From that moment, the platform monitors any changes to your code. Each branch can be deployed independently, generating a unique URL for each deployment, facilitating testing and collaboration.

3. Automatic Change Detection

When you make a commit or create a pull request, Vercel automatically detects the changes. This triggers the build process without any manual action on your part.

4. Build Process

Vercel automatically runs your build process. It compiles your application, performs optimizations (image compression, code minification, tree-shaking), and prepares all files for deployment. This process is fast and efficient, usually taking only a few seconds.

5. Preview Before Production

Before the application is published to production, Vercel generates a unique URL with a complete preview. You and your team can review all changes in a real environment, test functionality, and validate that everything looks and works correctly, without affecting end users.

6. Global CDN Deployment

Once changes are approved, Vercel automatically deploys your application across its global CDN network. Your content is instantly replicated across more than 300 strategically distributed data centers around the world.

7. Intelligent Caching and Content Distribution

Vercel automatically manages the cache for static and dynamic resources. It uses Anycast routing to automatically direct requests to the server closest to the user, reducing latency and significantly improving load times.

8. Serverless Function Execution

If your application includes serverless functions for backend logic (APIs, authentication, processing), Vercel executes them automatically on demand. They scale without manual intervention and you only pay for execution time.

9. Continuous Monitoring and Analytics

Vercel provides integrated tools to monitor your application's performance in real time. It includes performance metrics, load times, usage analytics, and integrates with external tools like Google Analytics, Sentry, and DataDog to provide detailed insights.

Vercel vs. Netlify vs. Heroku

Comparing web hosting solutions can be complex, but there are three key players in the market that stand out: Vercel, Netlify, and Heroku. All three services offer reliable hosting, but each comes with different features and benefits that make them suitable depending on the needs of each project.

Netlify and Vercel may seem to have many similar features, but they actually differ slightly. Both platforms offer a global CDN, serverless functions, CI/CD, and DNS management. Vercel offers a wide variety of integrations and features, such as automatic performance optimization, zero-configuration serverless functions, and an integrated development environment, while Netlify provides greater flexibility with manual control and customization.

Regarding serverless functions, both platforms are powered by AWS Lambda, meaning no AWS account is required, but you will need to use a programming language to write the code since it must run server-side logic. One advantage of Vercel is that it extends this further by also supporting Python and Ruby.

In terms of workflows, both platforms use Git as the source for your project, pulling source files from servers like GitLab, GitHub, and Bitbucket. After logging in, you can choose the repository for the connection, and the default configuration will conveniently run the entire deployment pipeline. Both platforms work very similarly in this regard. However, while Netlify struggles to provide Server-Side Rendering (SSR), Vercel makes it possible to quickly deploy SSR in Next.js applications.

Heroku is a cloud platform for application deployment and automation, while Vercel is a cloud platform for deploying static sites and serverless functions. Vercel focuses more on static sites and serverless functions, with features like atomic deployments and zero configuration — giving Vercel a considerable advantage over Heroku. Vercel also offers serverless backend services that allow the developer to focus solely on writing backend code without worrying about deployment or server maintenance.

Ultimately, it is entirely at the user's discretion to decide which serverless deployment platform to use. Vercel is definitely the better option if a project was developed with Next.js and requires CLI capability. All three platforms support caching; however, as mentioned above, Vercel excels at it when required for serverless functions. Therefore, while it primarily depends on your project's needs, Vercel stands out as the premier platform for collaboration.
