Upstash Redis Integration

Serverless, pay-per-request Redis — a drop-in REDIS_URL swap.

Upstash speaks the standard Redis protocol over TLS, so it's a genuine drop-in replacement for self-hosted Redis. Point REDIS_URL at your Upstash instance and rate limiting, caching, and Celery's broker all work unchanged.

Setup in 4 steps

1Create an Upstash Redis database and copy its TLS connection string
2Set REDIS_URL to the Upstash connection string in your .env
3Rate limiting and response caching work unchanged — same Redis client calls
4Celery broker and result backend also point at REDIS_URL — no separate config

What's included

Standard Redis protocol — zero code changes, only a connection string swap
Pay-per-request pricing avoids paying for an idle Redis instance in low-traffic apps
TLS by default, works well with serverless/edge deployment targets
Same rate limiting, caching, and Celery broker behavior as self-hosted Redis
Good fit when your compute is already serverless and a persistent Redis box is awkward

Code example

example.py

# .env — Upstash as a drop-in Redis replacement
REDIS_URL=rediss://default:<password>@<region>.upstash.io:6379

# Rate limiting, caching, and Celery all use this same URL — unchanged
@rate_limit(per_minute=60)
async def my_endpoint(...):
    ...
