WP Simple Pay vs Stigg
A side-by-side editorial comparison of WP Simple Pay and Stigg — release velocity, themes, recent moves, and the top alternatives to consider.
WP Simple Pay vs Stigg: at a glance
What is WP Simple Pay?
WP Simple Pay 4.17.4 brings payments and refunds into WordPress, no Stripe tab needed.
The feed's first entry since October 2025, 4.17.4 adds a Transactions page listing every one-time payment with status filters, search by customer email and spreadsheet export, plus refunds from inside WordPress. Earlier releases tracked Stripe's own surface: 4.16 added local payment methods and 4.13 compliance controls. The standout remains 4.14, which removed the paywall on recurring subscription payments.
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.

WP Simple Pay 4.17.4 brings payments and refunds into WordPress, no Stripe tab needed.
◆ Current state
The feed's first entry since October 2025, 4.17.4 adds a Transactions page listing every one-time payment with status filters, search by customer email and spreadsheet export, plus refunds from inside WordPress. Earlier releases tracked Stripe's own surface: 4.16 added local payment methods and 4.13 compliance controls. The standout remains 4.14, which removed the paywall on recurring subscription payments.
◆ Where it's heading
Until now the plugin competed on Stripe coverage and, with 4.14, on access. 4.17.4 points somewhere new: replacing trips to the Stripe Dashboard for daily payment work. That makes WordPress the place a site owner runs payments, not only collects them.
◆ Prediction
Expect the Transactions view to take on more payment operations, alongside continued fast-following of Stripe payment methods. Whether free subscriptions shifted monetization elsewhere isn't visible in these entries.
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.
