Vercel is a platform designed to simplify the development, deployment, and hosting of web applications, especially those built with modern frameworks like Next.js and React.
Before platforms like Vercel existed, launching an application was a long and complex process for developers. They had to manually configure servers with hosting providers such as AWS or DigitalOcean, which involved installing and adjusting tools like Nginx or Apache. Any mistake during this stage could halt the entire process.
Additionally, managing infrastructure presented other challenges. Developers needed to ensure that servers could handle the expected traffic, which involved manually setting up load balancing systems. Deployment was also tedious: uploading files via FTP, and if a code error arose, the process had to be repeated from scratch. Database management required additional configurations to ensure proper communication with the application.
As traffic increased, scaling the infrastructure became even more complex. It was necessary to configure additional servers and connect them to load balancers to avoid downtime. Furthermore, optimizing performance required integrating content delivery networks (CDN), adding more technical work.
Before launch, creating a staging environment was essential to ensure everything worked correctly, which meant duplicating servers and configurations. On top of that, teams had to implement test and deployment scripts through CI/CD tools, consuming even more time.
Vercel simplified many of these processes by offering a platform that combines automatic deployment, performance optimization, support for modern frameworks, and integrated collaboration and security features.

Advantages of Vercel
Vercel is known for its focus on simplifying the development and deployment of modern web applications. Here are the main advantages:
Git Integration: Vercel easily integrates with repositories on GitHub, GitLab, and Bitbucket, allowing automatic deployments whenever a commit is made—a point in a project's history where changes to the source code or other files are recorded.
Continuous Deployment (CD): Every change in the code triggers an automatic deployment, with preview environments that allow reviewing updates before making them public.
Content Delivery Network (CDN): It distributes applications through its global CDN, improving the speed and performance of the applications.
Automatic Optimization: Vercel optimizes images, code, and other resources, ensuring that applications load quickly on any device.
Support for Serverless Functions: It allows running serverless functions, which can be used to handle API requests, authentication, and other backend processes.
Simplified Deployment: Vercel allows developers to deploy web applications automatically and continuously from repositories like GitHub, GitLab, or Bitbucket, removing the complexity of manually configuring servers.
Optimized Performance: Vercel provides an integrated CDN service that globally distributes the content of applications, improving performance and reducing load times for users.
Automatic Scalability: Applications deployed on Vercel automatically scale based on traffic, eliminating the need for manual scaling configurations
Enhanced Collaboration: It facilitates collaboration among development teams by creating "preview deployments" so team members and stakeholders can review changes before they are integrated into production.
Integration with Modern Frameworks: Vercel is optimized to work with frameworks like Next.js, simplifying the management of dynamic routes, server-side rendering (SSR), and static generation.
Fast Deployment: Its infrastructure is designed to reduce deployment times, allowing changes to be reflected almost instantly.
Serverless Backend Functions: Vercel supports the use of "serverless functions" that allow developers to create backend logic without managing servers, making it easier to build APIs and custom functionalities.
Vercel is particularly popular among frontend developers due to its focus on performance and the simplicity of the deployment process.
How does Vercel work?
Vercel operates as a deployment and hosting platform that simplifies the development, deployment, and delivery of web applications. Here’s how Vercel works at each key stage of the application lifecycle:
1. Local Development
Supported frameworks and languages: Vercel supports a variety of frameworks and languages, including Next.js, React, Vue.js, Svelte, Angular, and more. Developers can work on their projects locally using their preferred development tools.
Vercel CLI: Vercel provides a Command Line Interface (CLI) that allows developers to test and deploy applications directly from their local environment.
2. Integration with Code Repositories
Repository linking: Vercel integrates directly with GitHub, GitLab, or Bitbucket repositories. Once a project is connected to Vercel, any changes made in the repository (such as a commit or pull request) can trigger an automatic deployment.
Branch deployments: Each repository branch can be deployed separately. Vercel generates a unique URL for each deployment, making it easy to review and test changes in different branches.
3. Automatic Deployment
Build process: When a commit is made, Vercel automatically detects the changes and runs a build process. During this process, Vercel compiles the application, performs automatic optimizations, and prepares the files for deployment.
Preview deployments: Before the application is published in production, Vercel generates a preview deployment. This preview allows developers and teams to review and test changes in a realistic environment without affecting the production application.
4. Content Delivery Network (CDN)
Global distribution: Once the application is ready, Vercel automatically deploys it through its global CDN. This ensures that users worldwide can access the application with fast load times, as content is served from servers near their location.
Smart caching: Vercel automatically manages the cache for static and dynamic resources, optimizing performance and reducing the application's latency.
5. Serverless Functions
Serverless execution: Vercel allows developers to write and deploy serverless functions directly from their repository. These functions can handle tasks like API requests, authentication, form processing, and more.
Automatic scalability: Serverless functions automatically scale in response to demand, meaning they can handle both small and large workloads without manual intervention.
6. Domain Management and Secure Sockets Layer (SSL)
Custom domains: Developers can link custom domains to their projects on Vercel. Domain configuration is simple, and Vercel automatically handles the provisioning of SSL certificates to ensure secure connections via HTTPS.
Automatic HTTPS: All applications deployed on Vercel have HTTPS enabled by default, providing additional security without needing extra configurations.
7. Monitoring and Analytics
Deployment monitoring: Vercel offers tools to monitor application performance, including performance metrics, load times, and usage analytics. These tools help developers quickly identify and fix issues.
Integration with analytics tools: Vercel integrates with third-party tools such as Google Analytics, Sentry, and other monitoring services to provide a more detailed analysis of application performance.
8. Scalability and Continuous Performance
Auto-scaling: Both static and dynamic applications scale automatically based on demand, eliminating the need to manage servers or complex infrastructure.
Continuous optimization: Vercel continues to optimize the application even after deployment, applying performance improvements and adapting to the best web development practices.
