The Complete Guide to Vercel Services

Vercel Services let you deploy multiple frontends and backends in one project on a shared domain. Learn how to define services in vercel.json, route requests by path prefix, and connect services with generated environment variables.

How Vercel Services run on Fluid compute

The backends in a Vercel Services project run as Vercel Functions on Fluid compute by default. Learn how optimized concurrency, Active CPU pricing, and per-service memory and maxDuration settings make multi-backend projects efficient.

Choosing how to structure your application on Vercel

Compare three ways to structure an application on Vercel (a single framework, one project with Services, or separate projects in a monorepo) and learn how to choose based on domains, deploy coupling, and languages.

Learn how to build Figma-style multiplayer cursors with Next.js and FastAPI, kept consistent across multiple Vercel Function instances using WebSockets and Redis.

Use Services to Deploy an App

When a project has multiple services, Vercel merges their routes into a single routing table and distributes incoming requests based on each service's route prefix.

Learn more about Vercel Services

For example, a Next.js frontend and a FastAPI backend in the same repository deploy together with shared routing, environment variables, and a unique domain, replacing the need to split monorepos into separate Vercel projects.
