Increase vs Kill Bill
A side-by-side editorial comparison of Increase and Kill Bill — release velocity, themes, recent moves, and the top alternatives to consider.
Increase vs Kill Bill: at a glance
What is Increase?
Increase ships steady quarterly batches of banking-API primitives, from FedNow to 3D Secure.
Increase is a banking-as-a-service API whose public changelog is a quarterly newsletter bundling many small additions. Recent quarters added payment rails (FedNow, Real-Time Payments, Push-to-Card), card capabilities (3D Secure, a disputes API, push provisioning), and developer ergonomics (multiple SDKs, IP-restricted keys, LLM-friendly docs). The cadence is predictable rather than punctuated by big launches.
What is Kill Bill?
Kill Bill keeps its billing engine on a slow, reliability-first maintenance cadence.
Kill Bill, the open-source subscription-billing platform, is in steady maintenance mode. The active 0.24.x line is a stream of bug fixes, dependency updates, and invoice-processing reliability work, while a 0.25.x branch has opened with point releases that so far ship as bare release-plugin tags without published notes. Nothing here changes the capability surface; the focus is correctness and operational robustness of billing runs.

Increase

◆ Current state
Increase is a banking-as-a-service API whose public changelog is a quarterly newsletter bundling many small additions. Recent quarters added payment rails (FedNow, Real-Time Payments, Push-to-Card), card capabilities (3D Secure, a disputes API, push provisioning), and developer ergonomics (multiple SDKs, IP-restricted keys, LLM-friendly docs). The cadence is predictable rather than punctuated by big launches.
◆ Where it's heading
The through-line is breadth: Increase is filling in the full surface a bank program needs — more rails, more card controls, more SDK languages, more compliance hooks — one quarter at a time. Nothing here reads as a pivot; it is methodical coverage of the money-movement and card stack.
◆ Prediction
The Q2 2026 digest is the next expected drop and will likely continue the pattern of card, dispute, and SDK additions, though the feed has been quiet since April, so its exact contents are not yet visible.
Kill Bill
5.0FINANCE
Kill Bill keeps its billing engine on a slow, reliability-first maintenance cadence.
◆ Current state
Kill Bill, the open-source subscription-billing platform, is in steady maintenance mode. The active 0.24.x line is a stream of bug fixes, dependency updates, and invoice-processing reliability work, while a 0.25.x branch has opened with point releases that so far ship as bare release-plugin tags without published notes. Nothing here changes the capability surface; the focus is correctness and operational robustness of billing runs.
◆ Where it's heading
The project is hardening the parts operators feel most: invoice failure handling, lock and retry behavior, and logging around aborted runs. The parallel 0.25.x line suggests the next feature-bearing release is being staged, but the visible changes remain incremental. Expect continued small releases stabilizing invoicing before 0.25.x carries anything user-facing.
◆ Prediction
Likely more 0.24.x/0.25.x point releases in the same vein — dependency bumps and invoice-reliability fixes — with 0.25.0's substantive changes only becoming clear once release notes accompany the tags.
