Adapty vs Kill Bill: at a glance
What is Adapty?
Adapty lets one paywall flow personalise itself with the app's own user data
Adapty has finished moving customers onto one builder: the old Paywall and Onboarding Builders were deprecated on October 1 and Paywalls now live inside Flows & Paywalls. Since then it added a yearly plan sold as 12 monthly payments on native iOS, and the November 9 roundup brings custom tags, where the app passes a value through the SDK and any text in a flow can display it, alongside flow funnels and screen animations.
What is Kill Bill?
Kill Bill keeps two release lines alive with small invoice-template changes.
Kill Bill ships on two lines: 0.25.x tags with no published notes, and 0.24.x releases that list small changes. Recent 0.24 work is about invoices: shared tenant branding (logo, company info, colours) in the HTML invoice generator, a revert of a branding template key, and partial-locale support for invoice and catalog translations.

Adapty lets one paywall flow personalise itself with the app's own user data
◆ Current state
Adapty has finished moving customers onto one builder: the old Paywall and Onboarding Builders were deprecated on October 1 and Paywalls now live inside Flows & Paywalls. Since then it added a yearly plan sold as 12 monthly payments on native iOS, and the November 9 roundup brings custom tags, where the app passes a value through the SDK and any text in a flow can display it, alongside flow funnels and screen animations.
◆ Where it's heading
With the migration done, the work has moved to making each flow do more: personalised copy, funnel analytics on flows, and animation. Adapty is turning the paywall builder into a general onboarding and conversion surface, with agent-built flows from August and pricing experiments like the 12-payment yearly plan layered on top.
◆ Prediction
Expect more SDK-fed personalisation and per-screen analytics inside flows, and the 12-payment yearly plan to extend beyond native iOS; the entries give no timeline for either.
Kill Bill
2.5FINANCE
Kill Bill keeps two release lines alive with small invoice-template changes.
◆ Current state
Kill Bill ships on two lines: 0.25.x tags with no published notes, and 0.24.x releases that list small changes. Recent 0.24 work is about invoices: shared tenant branding (logo, company info, colours) in the HTML invoice generator, a revert of a branding template key, and partial-locale support for invoice and catalog translations.
◆ Where it's heading
The visible feature work is per-tenant invoice presentation, with branding and localisation becoming configurable rather than hard-coded. The 0.25 line ships regularly but its notes are bare Maven tags, so its direction can't be read from the entries.
◆ Prediction
More invoice-presentation and localisation changes on 0.24.x are likely; what 0.25.x is building toward isn't visible in the entries.
