Python on Vercel is now generally available
Python is now a first-class language and runtime on Vercel, enabling you to build APIs, full-stack applications, and AI agents with native Python SDKs alongside JavaScript frontends in a unified deployment workflow. Vercel provides automatic framework support for FastAPI, Flask, and Django, plus SDKs for building agents, orchestrating workflows, and running isolated workloads.
is now a first-class language and runtime on Vercel. Build APIs, full-stack applications, and AI agents with native Python SDKs and a shared development and deployment workflow for your Python backend and JavaScript frontend.Python
Vercel handles the infrastructure so you can focus on your application:
Within your application, Python SDKs let you build agents, run untrusted code, and orchestrate durable workflows.
Use the SDKs individually or combine them in the same Python application.
For full-stack applications, allows you to deploy your frontend and backends together in one project, with shared previews and atomic deployments and rollbacks. Within that project, you can view logs by service and connect backends privately through service bindings.Vercel Services
