What is Vercel?

Vercel is a cloud platform for building, deploying, and scaling serverless applications and static websites. Vercel is popular among developers due to its ease of use, speed, and ability to handle large amounts of traffic. 

You can develop applications with a variety of programming languages and frameworks, and take advantage of features like automatic SSL, serverless functions, and continuous deployment.

In this article, we'll explore the benefits of using Vercel and dive into some of its key features. We'll also look at some of the platform's limitations and considerations to keep in mind when deciding if Vercel is the right choice for your next project.

What is Vercel?

Vercel is a cloud deployment platform for frontend developers, with which we can abstract away deployment, previews, CI/CD, API calls, and a whole host of other functionality. For free.

The rebranding from Zeit to Vercel took place in April 2020, reflecting its focus on its core product and its commitment to continuous improvement. Since its inception, Vercel has been instrumental in developing and popularizing the Composable architecture, which emphasizes static site generation and serverless functions for building fast and secure web applications.

Vercel is also the company behind the popular Next.js framework, a React-based framework for building server-rendered applications. The tight integration between Vercel and Next.js has made it a preferred choice for many developers building on composable architecture.

Vercel under the microscope

Deployments run on Vercel's edge network, which reduces the load times of your web application or website, adds a caching layer, and even implements backend functionality via serverless functions.

Manually configuring servers, messing around with Docker containers, setting up Nginx, and configuring DNS all seem like an unnecessary hassle to me now. 

My first impression when I tried Vercel was that it "just works," and that's a wonderful feeling for a developer. When you realize you've just saved a ton of time and will continue to do so in the future, those really are the moments to savor.

However, the real beauty for me has always been the price tag. I would never have been able to dig in and appreciate the above features if there'd been a financial barrier to entry – even a small one. 

Many companies will give you a taste of what they're offering, but you'd soon realize that what you need to be effective in the real world is behind a paywall. 

For example, I used to use Heroku. At the time, there were scores of developers who would upload their hobby projects to their free tier. What we didn't get for free was an SSL certificate, or a custom domain – both deal-breakers in the real world. 

So what do you get with Vercel exactly? Here's an overview.

• No need of configuration and seamless deployments of your frontend code: Vercel offers seamless deployment of frontend code with zero configuration. This means developers can instead focus on building their applications rather than wasting time configuring servers, Docker containers, or Nginx.

• Real-time insights, analytics, and performance metrics:  Real-time insights, analytics, and performance metrics help developers understand their applications' performance better.

• "Infinite" scalability: They offer infinite scalability, which means that applications can handle any amount of traffic, as long as one can afford it.

• Edge network (CDN, caching, edge functions): Vercel uses a global edge network that reduces the load times of web applications, adds a caching layer, and even implements backend functionality via serverless functions. 

• Static asset hosting (images, media): Their static asset hosting for all kinds of images and media comes very useful.

• Deploy previews and A/B testing: Vercel allows developers to test new features with deploy previews and A/B testing.

• 99.99% uptime: Vercel provides 99.99% uptime, which ensures that applications are always available and performing well.

• Continuous Integration and Deployment (CI/CD): Vercel offers continuous integration and deployment, which allows developers to quickly and easily push changes to production.

• Git-based workflow: Vercel uses a git-based workflow that makes collaboration and version control easy.

Free tier

Vercel has a free tier that allows developers to test and deploy their applications without any financial barriers to entry.

Supported frameworks and static site generators

The great thing about Vercel is that it supports various programming languages and frameworks, enabling developers to develop applications with their preferred tools. There are more than 40 supported frameworks, but some popular frameworks and languages supported by Vercel include:

1. Next.js: A popular React framework for building server-rendered applications.

2. Astro: A modern static site builder that delivers fast-loading, content-rich websites.

3. Nuxt.js: A Vue.js-based framework for creating Universal Vue.js Applications with server-side rendering.

4. Remix: A full-stack, server rendered framework, ideal for developers to create modern web apps.

5. React: A popular JavaScript library for building user interfaces, developed by Facebook.

6. Vue.js: A progressive JavaScript framework for building user interfaces.

7. Vite: A build tool that offers a rapid development server and optimized build process for modern web projects

8. Angular: A platform for building web applications, developed by Google.

9. SvelteKit: A newer, lightweight, and fast JavaScript framework for building user interfaces.

10. Ember.js: A framework for creating ambitious web applications focusing on developer productivity.

11. Eleventy: A simpler static site generator that works with multiple template languages.

12. Hugo: A fast and flexible static site generator built with Go.

There's also Gatsby.js, but it is not worth mentioning as a reliable framework anymore, since its updates and maintenance are almost abolished.

Keep in mind that while Vercel has built-in support for these popular meta-frameworks and static site generators, it can also be used with other tools and technologies, as it is a versatile platform for deploying web applications and static sites.

Its flexibility allows developers to work with their preferred tools, making it a convenient choice for many projects.

Security features

Security remains a critical element of any cloud platform. Luckily, Vercel has several security features and practices that protect user data and applications. Some of the key security features provided by Vercel include:

• Automatic SSL: Free SSL certificates for custom domains, ensuring encrypted connections between clients and the deployed applications. SSL certificates are issued automatically and renewed, reducing the hassle of managing SSL certificates manually.

• Secure default settings: Applications are configured with secure default settings. It's reducing the risk of vulnerabilities due to misconfiguration.

• DDoS protection: Their edge network provides built-in DDoS protection, safeguarding applications from various DDoS attacks.

• Immutable deployments: Each deployment on Vercel is immutable, meaning once it's deployed, it cannot be altered. This reduces the risk of unauthorized modifications and ensures that any changes to the application must go through the proper deployment process.

• Isolation of serverless functions: They have serverless functions run in isolated environments, limiting the potential blast radius of a security breach.

• Access control: They allows granular control over team member permissions through role assignments, helping to enforce the principle of least privilege.

• Regular security audits: Vercel conducts regular third-party security audits to ensure the platform maintains high security.

GDPR and privacy compliance: The service adheres to GDPR guidelines and implements privacy-focused practices to protect user data. This comes really handy if you are located within the EU.

Getting started with Vercel

The best way to get started with Vercel is by plugging in your git repository. I find this workflow extremely intuitive, and if you're not using git in 2025, well.. please learn git. 

There aren't a lot of technologies that I feel every single developer should adopt, but git is one of them.

Next, you register a Vercel account, connect to Github/Gitlab/Bitbucket using the intuitive and easy-to-follow steps in Vercel's dashboard, and Vercel will take care of the rest. It can identify which framework your code has been written in (it knows about 35 frameworks and auto-configures if your code uses one) and auto-deploys. 

You can add environment variables using the console too – which you definitely should do (never add sensitive data to git repositories, even private ones) – and then the app will build and deploy itself automagically.

Once your app is initiated, custom domains can be added for free, SSL/TLS certs are issued (and auto-renew), and your app is ready to be served from the edge network. There are no performance hits for using the free tier either; your free app is production-grade and can be relied upon for business-critical operations.

From there, Vercel has a unique offering – real-time analytics. 

I love Google Chrome's Lighthouse, where I can get insights about how my app might perform, but that's just a simulation – my app's users may have a totally different experience for various reasons. 

Vercel at scale

Okay, so hopefully, I've sold you on the free tier. But what about enterprise-grade apps? 

Another really nice facet of Vercel is that once the foundations are laid, scaling is brainless. If you suddenly have a huge spike in traffic, Vercel will auto-scale. This is the beauty of serverless architecture. With scaling taken care of, all you then need is a way to manage deployments among your team members. 

Everything is git-based so most collaboration will happen on Github or Bitbucket. All that needs to happen on Vercel is to assign permissions to the appropriate team members, which we do via roles. 

You can be assigned as an owner, member, developer, billing, or viewer; these different roles become available on different plans. You'll start paying actual money at this stage, but it's still pennies compared to running an entire DevOps team to keep your application running smoothly.

Vercel vs Netlify

Netlify was founded in 2014, a year before Zeit (which later rebranded as Vercel in 2020).

They're both great platforms, and honestly, many of the features that I love about Vercel are ones that I had discovered earlier by using Netlify. With both platforms, you get auto-scaling, auto-deploys, edge functions, git-integration, CI/CD, A/B testing, and more. 

In the past, some features of one had not arrived in the other – edge functions being a notable example, and SSR capabilities – but as these features developed, they were eventually adopted by both companies.

One key difference between these two giants, which still arguably stands, is focus. 

Netlify is sometimes considered wider in scope than Vercel – it tries to do more, while Vercel concentrates its efforts. For Netlify, this is evident from their Integrations Hub, with hundreds of partners to choose from, companies like Auth0, Cloudinary, Cypress, or Contentful.

In contrast, Vercel has very much doubled down on its flagship offering, Next.js. 

The React.js as any frontend developer will tell you, the Javascript library still reigns supreme in adoption and popularity. And among React developers, Next.js is extremely well-loved. 

Hence, the tight integration between Vercel and Next.js is self-evident. If you're using Next.js (and many, many developers are), there is a good chance Vercel will be a perfect fit for hosting your application.

Here's a handy table that summarizes the differences:

So, which one to choose? We could put it this way: If you're building with Next.js, Vercel is the natural fit. If you need broader integrations and enterprise solutions, Netlify is a strong alternative

Vercel use cases

As discussed, Vercel is a great platform that can be used for various use cases. Below, we've assessed some of the most common use cases for Vercel:

• For web applications: If you're looking to build and launch a fast and responsive web app, Vercel is the way to go! It's optimized for performance and will help you deliver a top-notch user experience.

• Static websites: Vercel is also great for hosting and deploying static websites. They load quickly and work seamlessly no matter where your users are located.

• Serverless functions: Want to build backend logic for your application without the hassle of a dedicated server? Vercel has got you covered with their support for serverless functions.

• Progressive web apps: Vercel also makes building and deploying PWAs that work across multiple devices and platforms easy.

• eCommerce websites: If you're building a composable commerce storefront, Vercel is a fantastic choice. It's optimized for these sites and supports popular eCommerce frameworks like Shopify and Magento.

• Developer portfolios: Lastly, if you're a developer looking to showcase your work, Vercel is an excellent choice for building and deploying your portfolio. They have support for popular front-end frameworks like React and Next.js, so you can really make it your own.

Closing thoughts

Switching from traditional server architecture to serverless Composable methodologies has given the frontend developer community a boost in productivity on a scale that's rarely seen. 

Vercel is a streamlined, intuitive, and cost-effective platform for getting your web applications out of your brain and into the world. 

There's no barrier to entry, and I honestly feel that the front-end developers who aren't using it in 2025 are mainly composed of those who don't know about it.

The future has arrived. Get on board.
