How to deploy Next.js on Vercel: advantages, limits, and alternatives

Practical guide on how to deploy Next.js on Vercel: advantages, limits, and alternatives with examples and infrastructure comparison.

You have a Next.js frontend and you want to see a public link after every push. That's where Vercel is very convenient. The problem appears when you mix that website with an API that processes long-running jobs, a database, or a bot that needs to stay on all day.

I'm not going to sell you the idea that one platform is perfect for everyone. What's useful is understanding what work it saves you, what work remains yours, and how much it can cost to maintain it when the project stops being a test.

Vercel: what it really offers you

Vercel stands out for its integration with Next.js, branch previews, and global frontend distribution. It's not simply "a VPS with a button": its execution model and limits are different. Deployment can include server-side rendering, functions, and static resources, but it doesn't give you root access on a machine to install any service.

An example you could have tomorrow

A booking platform has public pages, an admin panel, and a backend that confirms payments. You can leave Next.js on Vercel with previews to review the interface, while FastAPI, PostgreSQL, and a worker run on an ArduMaker VPS. You connect both via api.tudominio.com and HTTPS. You don't need to choose one platform for absolutely everything.

How to start without overcomplicating things

1. Prepare the repository and verify that npm run build completes without errors.
2. Connect GitHub to Vercel and import the Next.js project; check the root directory if you have a monorepo.
3. Define public and private variables correctly. NEXT_PUBLIC_* variables are incorporated into the browser-visible code.
4. Test the preview before pointing the domain, especially SSR routes and API requests.
5. Review logs and consumption if a route executes slow queries or long-running jobs.

The fifth step is often the one that gets skipped: opening the application from another device, performing a write operation, checking a log, and verifying it again after restarting. That is worth more than a screenshot where the panel says "deployed".

The mistake I would avoid

Do not use localhost in code that runs in the browser: there it points to the device of whoever opens the website. Also, do not expose credentials in public variables. If you need persistent WebSockets or long-running jobs, check beforehand if they fit Vercel's execution model.

There is another simple rule: if the project has clients or payments, do not experiment with migrations directly on the only copy of the database. Test in a separate environment, keep a verifiable copy, and prepare how to roll back.

How would I solve the same in ArduMaker?

In ArduMaker you can run Next.js as a Node service on a VPS, connect Git and associate a domain. You can also host the backend and PostgreSQL in that environment. You gain process control, but you do not automatically receive PR previews or the CDN distribution that Vercel offers for the frontend.

In a typical case, you could create the VPS in ArduMaker, connect the Git repository, install or manage PostgreSQL according to the application, define the execution process and publish an HTTPS domain. If there is a worker that takes several minutes, separate it from the HTTP service. And if the project has several clients, organize them by Company to avoid mixed permissions and resources.

What I would look at before paying or migrating

I wouldn't choose based on a single figure on the pricing page. Note CPU, RAM, persistent storage, traffic, backups, support, and maintenance time. If you need to add a managed database, a workers service, or a licensed panel, include them. If you want redundancy between servers, that also needs to be designed: a VPS alone is not high availability.

So, which one would I use?

Vercel is usually more straightforward for frontend Next.js with collaborative work. ArduMaker makes sense if the application needs its own servers and processes; for many teams, the combination is a reasonable solution.

An honest test: publish a minimal API, connect it to a database, stop the process to see what the system logs, and try to recover it. The platform with which your team can repeat those steps without suffering is usually the one that brings you the most value.

The final idea: first solve a real problem with the tool. Then compare how much effort it takes to maintain it. That's where the difference between a demo and an application you can deliver to a client appears.
