Comparison
FluidKit vs Adapty
Adapty is a subscription platform: SDK, paywalls, A/B tests and revenue analytics, with onboarding built into its Flow & Paywall Builder. FluidKit only does onboarding and works with whatever billing you already have. If you want billing and onboarding from one vendor, Adapty is the stronger choice today. If you want onboarding without adopting a subscription SDK, that's what FluidKit is built for.
Facts about Adapty checked on , from the sources listed below.
On October 1, 2026 Adapty deprecated its legacy Onboarding Builder. Existing onboardings keep running, and new ones are built in the Flow & Paywall Builder, which renders natively and needs Adapty SDK v4 or later.
