You'll still be building management UI over their system (it doesn't understand or validate actor types, tenants, etc, so you have to do that.).

But at high throughput, you might want something with dedicated professional love. Ten thousand feature flags, being checked at around 2 (or 200) million RPS from multiple deployments... I don't want to be the team with that as their side project. And once you're talking a team of three to six engineers to build all this out, maybe it makes sense to just buy something for half a million a year. Assuming it can actually fit your model.

But it's not a side-project in most implementations it's part of the app itself.

Side project means it’s not that team’s primary focus.

The scale is easy in practice, cause you outsource to a CDN. But everything takes time and has opportunity cost.

Maybe we've worked with different FF systems, but anything that involves a call more expensive than an RPC would be lethal to request latency. Calling out to a CDN forty five times per inbound request would be... Infeasible

A background thread long polls the CDN, updating a local hashmap on change.
