The gist VS growthbook

Graphile worker has been great for me because it's a library that works with Postgres that allows me to queue jobs and execute them on the server without adding too many additional layers of complexity for being able to accomplish async tasks. (I'm aware of how popular bull is, but I don't want to add another data-store only for async tasks)

Bull is currently in maintenance mode, we are only fixing bugs. For new features check BullMQ, a modern rewritten implementation in Typescript. You are still very welcome to use Bull if it suits your needs, which is a safe, battle-tested library.

I use bullmq with node

You might consider using a queue for processing the request. I've found bullMQ, which works with Redis, to be a nice developer experience.

BullMQ is a pretty solid choice: https://github.com/taskforcesh/bullmq It's the successor of Bull: https://github.com/OptimalBits/bull

BullMQ

For Node.JS you can use something like BullMQ (https://github.com/taskforcesh/bullmq) and then dispatch jobs to the message queue with your worker handling the jobs. You can read about an example for Bull MQ here (https://deadsimplechat.com/blog/best-nodejs-schedulers/#2-bull)

bullmq seems like an open issue

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,

Why did we choose GrowthBook?

I would not adopt a platform that did not support exclusions. I think you should create a marketing page explaining the ways you are superior to the competition. Right now I would pick https://www.growthbook.io/

Seems that no-one mentioned my favorite feature flagging + A/B testing open source tool: https://www.growthbook.io/

Currently have the task of spiking a technical setup for A/B testing within our team application. I've already been looking at Growthbook and react-ab-test, what other tools / sources of info do people normally reach for in their own experience?

What are the differences to Flagr, GrowthBook or Flagsmith?

I work in the marketing analytics field, so I'm not that deep into product (even though I'm dabbling and will jump at the opportunity when one presents itself). Feature flags are being used to roll out experiments. Essentially, you publish code/experiments to the app source code, and based on the flag it shows a control or variant. The flag is fetched from a server and the rollout can easily be disabled if issues crop up. https://www.growthbook.io/ is an open-source tool that seems to be getting a bit of traction.
