I'm pretty sure Vercel won't be able to deploy a redis cache without using a redis cloud offering.

Edit: I deployed this version to docker running in a linux server and as you can see there is big improvements in the performance. See the deployed version here.

Thats really awesome!

The vercel preview is working fine.
Do you want to edit the readme and include this instance?

No, it's not going to work with the current deployment configuration. As in the api will work without the cache. I've set it up to run redis inside the docker container. I checked out Vercel and it's currently going to run whatever is in the Vercel Function. It's stateless.

The only way to keep Vercel and run a Redis cache is to implement a cloud based one https://redis.io/docs/latest/operate/rc/cloud-integrations/vercel/
