Why would you not use the same service to handle them? Less is more.

Having worked at a large company that misuses feature flag service for everything, here are some examples why you shouldn’t:

- one team uses feature flag for product gating. Feature flag service goes down. Users temporarily got locked out of the features they paid for.

- one team uses feature flag for dynamic pricing by leveraging targeting rules (how hard is it to write a bunch of if else in code?). It’s evaluated against all users, even if they are not active (for analysis reasons). Feature flag service charges by MAU. We have millions of users. Our feature flag service bill is now 6 digits per year.

- one team uses feature flag as literal json store instead of a proper db (god knows why). Someone updated the value but the “schema” is wrong. Shit breaks.
