Stigg vs Purchasely: at a glance
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.
What is Purchasely?
Purchasely puts its Management API in the terminal and in AI coding agents
Purchasely is an SDK and console for in-app subscriptions and paywalls. Version 6.2 in October let apps send their own business events to trigger campaigns and linked every purchase to the paywall, placement and test that drove it. On November 5 it released a CLI in beta that exposes every Management API operation as a command, shows app metrics in the terminal, and installs a Purchasely plugin into AI coding agents, with dry runs, plan-then-apply and a read-only mode for safe writes.
Stigg vs Purchasely: editorial side-by-side
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.
Purchasely
6.3FINANCE
Purchasely puts its Management API in the terminal and in AI coding agents
◆ Current state
Purchasely is an SDK and console for in-app subscriptions and paywalls. Version 6.2 in October let apps send their own business events to trigger campaigns and linked every purchase to the paywall, placement and test that drove it. On November 5 it released a CLI in beta that exposes every Management API operation as a command, shows app metrics in the terminal, and installs a Purchasely plugin into AI coding agents, with dry runs, plan-then-apply and a read-only mode for safe writes.
◆ Where it's heading
The SDK releases have steadily moved control of paywalls and campaigns out of app code and into the Console. The CLI moves it again, into scripts, CI and coding agents, with guardrails designed for automated writes.
◆ Prediction
The CLI needs Management API access enabled by Purchasely staff, so the next likely step is broader self-serve access, or more agent-facing tooling built on the same API.
