SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Choosing the right backend architecture on Vercel is difficult when you must decide between Functions, Services, containers, Workflow, Queues, and Marketplace databases without a clear decision framework. ## Core Features & Use Cases - Product Mapping: Maps workload types (HTTP APIs, WebSockets, background jobs, durable workflows, scheduled tasks) to the correct Vercel product. - Framework Guidance: Lists supported backend frameworks including Express, Fastify, Hono, NestJS, FastAPI, Flask, Django, and Go. - Database Selection: Recommends Marketplace storage integrations such as Neon, Supabase, Upstash, MongoDB Atlas, and Turso. - Use Case: When migrating an existing Express API with a Dockerfile and a Postgres database to Vercel, use this Skill to decide between container images on Functions versus a native runtime, and to pick a Marketplace Postgres provider. ## Quick Start Use the create-a-backend skill to plan the architecture for deploying my FastAPI service with a Postgres database on Vercel.

FAQPage Schema
How do I choose between Vercel Functions and Vercel Services for my backend?

Use Vercel Functions for standard request/response backends like HTTP APIs and webhooks. Use Vercel Services when a frontend and one or more backends should deploy together with shared routing, preview URLs, and rollbacks.

What backend frameworks does Vercel support?

Vercel supports Node.js frameworks including Express, Fastify, Hono, NestJS, Koa, and Elysia, plus Python frameworks FastAPI, Flask, and Django. Go is also supported as a Functions runtime, and Next.js Route Handlers fit backends within Next.js apps.

Can I deploy an existing Dockerfile as a backend on Vercel?

Yes, container images on Vercel Functions support existing Dockerfiles, custom runtimes, and system dependencies. They run as autoscaling, stateless Functions rather than always-on container hosts, and can be composed with Services.

When should I use Vercel Queues versus Vercel Workflow?

Use Vercel Queues for background jobs, buffering, fan-out, and direct message routing. Use Vercel Workflow for durable multi-step business logic that needs retries, sleeps, or external event handling.

How do I add a Postgres database to a Vercel backend?

Provision Postgres through Vercel Marketplace integrations such as Neon, Supabase, or Prisma so credentials are injected into the project automatically. Keep the database close to the Functions region and use a serverless-compatible connection pool.
