Run multiple frameworks in one project with Vercel Services

You can now deploy multiple frontends and backends together within a single Vercel project.

Vercel Services is now available, allowing you to deploy full stack apps with multiple frameworks on a shared domain, where services talk to each other privately and deployments build, preview, and roll back together.

Services are defined in vercel.json:

{

"services": {

"my_frontend": {

"root": "frontend/",

"framework": "nextjs"

},

"my_backend": {

"root": "backend/",

"entrypoint": "main:app"

}

},

// my_backend has no public route

// it is only reachable from my_frontend internally

"rewrites": [

{

"source": "/(.*)",

"destination": { "service": "my_frontend" }

}

]

}

Vercel handles routing, builds, and environment variables automatically.

From there, your services show up across the dashboard and CLI:

• The Deployments panel visualizes the services graph

• The Logs UI filters by individual service

• vercel dev runs every service locally for a production-like environment

Services talk to each other internally with the new bindings key, without routing through the public internet:

{

"services": {

"my_frontend": {

"root": "frontend/",

"framework": "nextjs",

"bindings": [

{

"type": "service",

"service": "my_backend",

"format": "url",

"env": "BACKEND_INTERNAL_URL"

}

]

},

"my_backend": { ... }

},

"rewrites": [ ... ]

}

The binding exposes my_backend to my_frontend as an environment variable.

The frontend reaches the backend privately through the URL in BACKEND_INTERNAL_URL:

export async function GET() {

const url = new URL("/users", process.env.BACKEND_INTERNAL_URL);

const res = await fetch(url);

const users = await res.json();

return Response.json(users);

}

The route fetches from my_backend using that variable and returns the response.

Most frameworks run with zero configuration. Framework-defined infrastructure means each service's framework is auto-detected and auto-provisioned, from FastAPI and Flask to Express and Hono, with first-class support for Go and Rust. Services run on Fluid compute with Active CPU pricing, so you only pay for the time your code is actually running.
