Kill Bill vs Stigg
A side-by-side editorial comparison of Kill Bill and Stigg — release velocity, themes, recent moves, and the top alternatives to consider.
Kill Bill vs Stigg: at a glance
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.
What is Stigg?
Stigg is moving from pricing plumbing to AI-operated contracts, and now ships inside Stripe Projects.
Stigg's recent releases cover two layers. The runtime got faster: sub-10ms entitlement checks and fail-safe resilience now reach the REST SDKs, and Plans and Add-ons load faster in the app. The commercial layer grew as well, with a natural-language contracts AI skill, a dedicated credit configuration section, and export-failure webhooks. Stigg is now also listed as a provider on Stripe Projects.
Kill Bill vs Stigg: editorial side-by-side
Kill Bill
5.0FINANCE
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.
Stigg
6.3FINANCE
Stigg is moving from pricing plumbing to AI-operated contracts, and now ships inside Stripe Projects.
◆ Current state
Stigg's recent releases cover two layers. The runtime got faster: sub-10ms entitlement checks and fail-safe resilience now reach the REST SDKs, and Plans and Add-ons load faster in the app. The commercial layer grew as well, with a natural-language contracts AI skill, a dedicated credit configuration section, and export-failure webhooks. Stigg is now also listed as a provider on Stripe Projects.
◆ Where it's heading
Contract Management went from beta in August to AI-operable in September, which positions Stigg as the system of record for sales-led deals as well as self-serve plans. The Stripe Projects listing shifts attention to acquisition: Stigg is placing itself where developers already set up billing, rather than waiting to be integrated afterwards.
◆ Prediction
Expect more distribution-channel listings and agent-facing skills alongside Contract Management leaving beta; the entries don't show which will come first.
