Vercel Adds Routing Rules for Python Projects

What shipped: Vercel routing rules — response header manipulation and URL rewrites — now work with Python projects on the platform.

What changed: Previously limited to Node.js deployments, routing rules can now be applied to FastAPI, Django, and Flask apps. You can set response headers (CORS, security policies) and rewrite requests at the CDN edge — no code changes or redeploy required. Rules are managed through the CDN tab in the dashboard, the Vercel CLI, the Python SDK / REST API, or vercel.json.

Why a builder cares: Python web apps on Vercel just got the same edge-configurable routing that frontend projects have had. If you're running an API on FastAPI or a Django app behind Vercel's CDN, you can now tweak headers and redirect paths without touching your Python code or triggering a build. One less deployment cycle for config changes.
