throng VS KeystoneJS

In order to try and mitigate the OOMs. I read the Background Jobs in Node.JS with Redis blog post and implemented Heroku Data For Redis with ioredis, BullMQ and Throng,

This is a memory intensive process though and Heroku is OOM'ing with R14 errors. For this they recommend migrating intensive work like this to a Background Job via Redis, implemented in Bull and Throng

Keystone 6: The GraphQL Behemoth

Also, there are lots of exciting web frameworks that use Prisma as their default ORM layer (like RedwoodJS which is built by the founder of GitHub, Amplication which recently raised $6.6M in seed funding, Wasp (YC W21) or KeystoneJS) which should give you some more validation that Prisma is being used in a lot production applications :)

KeystoneJS https://keystonejs.com

https://keystonejs.com/ is a nice smaller alternative.

Keystone.js is a content management system and framework for creating server-side applications that interact with a database. It is based on the Express platform for Node.js and uses MongoDB for data storage. It is an alternative to CMS for web developers who want to create a data-driven website, but do not want to move to the PHP platform or too large systems such as WordPress.

I have a website I've built in nextjs frontend using keystonejs as a cms written in node.

I have a working graphql server written in Keystone CMS and hosted on Heroku.

Even you can use WordPress through their API, I would recommend you to try KeystoneJsKeystone Js CMS, as others suggested before, there are several headless CMSs but Keystone is totally free, open source and self hosted, you can even deploy on vercel. take a look

The most ok alternative would probably be something like Keystone.
