Firefly III
Firefly III ships seven develop builds in six days, still with no changelog attached.
A side-by-side editorial comparison of Mollie and Stigg — release velocity, themes, recent moves, and the top alternatives to consider.
Mollie's Payments API now supports embedded saved cards — a real concession to merchants who own their checkout.
Mollie just enabled saving cards during checkout directly via the Payments API, letting merchants build fully embedded 1-click flows without redirecting to Mollie's hosted page. Alongside it: partial credit notes for specific invoice items, a new Methods Component beta for custom low-code checkouts, expanded webhook reference with permission requirements, and integration updates (Prestashop 6.4.3, VirtueMart for Joomla). Several smaller dashboard ergonomics ship in the same window.
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.

Mollie is repositioning from a hosted-checkout payments processor toward a more developer-platform shape — saved cards in the Payments API, the Methods Component low-code SDK, and the Unmatched credit transfers API all point the same direction. The webhook reference work and Token ID search in logs suggest the team is building for serious integrators who run Mollie alongside other payment rails.
Expect more checkout primitives to migrate from hosted-only to API-accessible (likely subscriptions and recurring billing next), and the Methods Component beta to graduate with deeper customization. Continued European e-commerce platform integrations remain on the conveyor belt.

Credits have become Stigg's main pricing unit, and the product is adapting them to AI workloads whose cost isn't known up front. Reserve and settle, together with the governance SDK, turns the entitlements engine into a spending control for agents.
Expect the governance SDK to use reservations directly for agent limits, and more reporting on reserved versus settled usage.
