Progressive frustration
I first tried to use growthbook. They had only react support. I thought - I could use the js sdk and work around it. Ok fine. It seemed a bit complicated to use in terms of their UI. Okay fine, I try to find an easier one maybe I can self-host. That way I could even put it behind cloudflare CDN and use caching on it and clever cache-busting when I change values could help propagate changes. Okay fine I have a plan. I ended up going with Flagsmith instead. It was even easier. Perfect.

Show HN: Featurevisor – Git based feature flags and experiments management
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/

Good Packages / Tools for A/B Testing Setup within React Apps?
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?

Product Led Growth challenges
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.
