COMPARE / FEATURE FLAGS
Feature flags, with the math.
Compare hosted flag configuration for one application and its release team.
One application. Requests mean SDK configuration fetches, not local flag evaluations or monthly users. Match actual SDK polling and caching before comparing. Flagsmith identity and trait writes are excluded. ConfigCat transfer is entered separately. Taxes, custom contracts, self-hosting and optional add-ons are excluded.
