Adapty vs Kill Bill
A side-by-side editorial comparison of Adapty and Kill Bill — release velocity, themes, recent moves, and the top alternatives to consider.
Adapty vs Kill Bill: at a glance
What is Adapty?
Adapty is handing paywall construction to coding agents and adding a credits economy underneath
Adapty's Flow & Paywall Builder is now the centre of the product, and August pointed a coding agent at it: a flow-generator skill lets Claude Code, Codex or Copilot CLI read a flow config through the CLI, rewrite it and preview the result. Alongside that, virtual currencies gave the platform a credits primitive, and Refund Saver reached Google Play as chargebacks there started costing developers real money.
What is Kill Bill?
Kill Bill's 0.25 line ships tags with no notes while 0.24 does the actual work
Kill Bill is publishing two lines that behave nothing alike. The 0.25 releases — 0.25.1 through 0.25.4 across July and August — carry a single line of body text apiece, the maven-release-plugin's tag-copy message, with no changelog at all. The 0.24 line carries structured notes with issue references, and it is where the recent user-facing work sits: shared tenant branding for HTML invoices in 0.24.20, then a revert of part of it in 0.24.21 five days later.

Adapty is handing paywall construction to coding agents and adding a credits economy underneath
◆ Current state
Adapty's Flow & Paywall Builder is now the centre of the product, and August pointed a coding agent at it: a flow-generator skill lets Claude Code, Codex or Copilot CLI read a flow config through the CLI, rewrite it and preview the result. Alongside that, virtual currencies gave the platform a credits primitive, and Refund Saver reached Google Play as chargebacks there started costing developers real money.
◆ Where it's heading
Two directions are running together. Monetization is broadening past subscriptions into balances and consumables, and authoring is moving from the dashboard toward the terminal and the agent. The one-click legacy paywall migration signals the old builder is being retired rather than maintained.
◆ Prediction
Expect the agent skill to extend from flows into the rest of the CLI surface — products, placements, campaigns — so a whole monetization setup can be generated and reviewed as config.

Kill Bill's 0.25 line ships tags with no notes while 0.24 does the actual work
◆ Current state
Kill Bill is publishing two lines that behave nothing alike. The 0.25 releases — 0.25.1 through 0.25.4 across July and August — carry a single line of body text apiece, the maven-release-plugin's tag-copy message, with no changelog at all. The 0.24 line carries structured notes with issue references, and it is where the recent user-facing work sits: shared tenant branding for HTML invoices in 0.24.20, then a revert of part of it in 0.24.21 five days later.
◆ Where it's heading
Reading the 0.24 line alone, the theme is invoice-generation robustness continuing from 0.24.18's error handling, retries and account parking, into 0.24.20's branding refactor. The August 12 revert of the template branding key suggests that refactor is not settled. What the 0.25 line contains is genuinely unknown from this feed — the tags exist, the notes do not.
◆ Prediction
Expect the tenant-branding work to return in a corrected form on the 0.24 line, since the revert removed the key rather than the surrounding refactor. Whether 0.25 is a development line or a release line is not something these entries answer.
