To host a Next.js app on Netlify, push the code to a Git provider, connect the repository in the Netlify dashboard, and let Netlify’s Next.js adapter handle the build - it detects the framework, runs next build, and wires up static pages, server rendering, and API routes automatically. Next.js has been natively supported for years, so the modern experience is close to zero-config. The part worth understanding is what actually runs where once it is deployed.
The deploy is genuinely a few clicks. The useful knowledge is which parts of your Next.js app become static files, which become functions, and what that means for cost and behaviour.

The deploy, start to finish
Put your Next.js project in a GitHub, GitLab, or Bitbucket repository. In the Netlify dashboard, choose Add new site and pick the repo. Netlify detects Next.js and fills in the build command (next build) and leaves the publish directory to the adapter - you usually do not set it manually.
Click deploy. Every push to the connected branch then triggers a fresh build and deploy, with instant rollbacks to a previous version if one goes wrong. If you prefer the terminal, the Netlify CLI deploys the same project without leaving the command line. For a from-scratch start, the Next.js platform starter template is a one-click way to get the structure right.
The adapter and what it does
The reason this is nearly zero-config is the Next.js adapter. When you deploy, it maps Next.js concepts onto Netlify’s primitives: statically generated pages become CDN-served files, server-rendered pages and route handlers become serverless functions, and image optimization and middleware are wired to the equivalent Netlify features.
You do not configure most of this - the adapter reads your Next.js output and does it. What this means for you is that a page using getStaticProps is cheap and fast (it is a file), while a page rendered per request runs a function on every hit, which has different performance and cost characteristics. Knowing which of your pages is which is the useful mental model.
Dynamic routes, API routes, and the gotchas
Dynamic routes, preview mode, and API routes all work, because they map to functions. The common surprises are at the edges: client-side fetch calls are always served by the current deployment rather than the one that rendered the page, so skew between a cached page and a newer function response is something to be aware of.
Environment variables are set in the Netlify UI and injected at build and runtime - a missing one is the most frequent cause of a build that passes locally and fails in CI. And anything that assumed a long-running server (a persistent in-memory cache, a background worker) does not fit the function model and needs rethinking.
Before you pick a host
Netlify is an excellent fit for a Next.js app that is mostly static with some serverless. Before committing any host, check three things against your app’s shape. How much of the app is per-request server rendering versus static - because that drives function invocation cost. Does it need a long-running process or background jobs - which the function model does not provide. And what does bandwidth cost beyond the free allowance, since a popular site’s egress is often the real bill.
Those three answers, not the deploy experience, decide whether a host is right - the deploy is easy everywhere now.
Where RunxBuild fits
If your Next.js app has outgrown the serverless shape - it needs a long-running server, background workers, or a managed database beside it - RunxBuild runs Next.js as a full service from your GitHub repo, with build logs, a live route, environment variables, and rollback, documented under services/next.
That is the difference in model: a function-based host is ideal when the app is static-plus-functions, and a service-based host fits when the app is a real server with a database and workers. Model the pieces - the service, the database, the bandwidth - in the calculator so the choice is based on what your app actually is rather than how nice the first deploy felt.
How this fits the rest of the stack
The cost of a project is the sum of its line items, not the headline number, and the RunxBuild hosting calculator is the right place to add them up: the service, the database, the storage, the bandwidth, each a separate figure. Model it before committing, not after the first invoice. The RunxBuild dashboard is where the running project shows its real usage in one place.

FAQ
Is Next.js supported on Netlify?
Yes, natively and for several years. Netlify’s Next.js adapter detects the framework, runs next build, and maps static pages to the CDN and server-rendered pages and API routes to serverless functions automatically, so the deploy is close to zero-config.
How do I deploy a Next.js app to Netlify?
Push the project to a Git provider, connect the repository in the Netlify dashboard, and let it detect Next.js and set the build command to next build. Each push then triggers a build and deploy. The Netlify CLI does the same from the terminal if you prefer.
Do Next.js API routes work on Netlify?
Yes. API routes and server-rendered pages become serverless functions, and dynamic routes and preview mode work. The caveat is the function model: there is no long-running server, so persistent in-memory state or background workers need a different approach.
Why does my Netlify build fail when it works locally?
The most common cause is a missing environment variable - locally it is in your shell or .env, but on Netlify it must be set in the site’s environment settings and injected at build and runtime. Check those first before deeper build debugging.
When should I not use Netlify for Next.js?
When the app needs a long-running process, background jobs, or a tightly coupled managed database - the serverless function model does not provide those. A service-based host that runs Next.js as a full server is a better fit once the app is more than static pages plus functions.
