Mollie vs Stigg
A side-by-side editorial comparison of Mollie and Stigg — release velocity, themes, recent moves, and the top alternatives to consider.
Mollie vs Stigg: at a glance
What is Mollie?
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.
What is Stigg?
Stigg moves its entitlements and credit checks inside agent orchestrators and gateways.
Stigg now runs inside agent orchestration layers, applying entitlements, credits and budgets to each step of an agent run, and its Agent SDK supports solo.io and agentgateway out of the box. It also lets customers bill subscriptions through Airwallex invoices and payment links. This lands a day after new pricing with a free plan and monthly billing, and three days after Usage Governance went GA.

Mollie

Mollie's Payments API now supports embedded saved cards — a real concession to merchants who own their checkout.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Stigg
7.5FINANCE
Stigg moves its entitlements and credit checks inside agent orchestrators and gateways.
◆ Current state
Stigg now runs inside agent orchestration layers, applying entitlements, credits and budgets to each step of an agent run, and its Agent SDK supports solo.io and agentgateway out of the box. It also lets customers bill subscriptions through Airwallex invoices and payment links. This lands a day after new pricing with a free plan and monthly billing, and three days after Usage Governance went GA.
◆ Where it's heading
Stigg is placing its billing engine at the points where AI agents spend money: the orchestrator, the gateway and credit reservation before each operation. Billing-backend breadth, now Airwallex invoicing, keeps pace in the background.
◆ Prediction
Expect more gateway and orchestrator integrations in the Agent SDK and its move out of beta. Billing backends will likely keep widening around Airwallex and its peers.
