Purchasely vs Stigg: at a glance
What is Purchasely?
Purchasely 6.0 overhauls the SDK's core — initialization, presentation, and purchase flow get a full rewrite.
Purchasely is an SDK for managing in-app subscriptions and paywalls on iOS, Android, and web. SDK 6.0 modernized the initialization model, screen presentation, action handling, and purchase flow control across all platforms — a major version that breaks backwards compatibility but aligns the SDK with current platform requirements. SDK 6.1 builds on this with a web-to-app redemption flow and proxy routing for environments where the Purchasely API is unreachable.
What is Stigg?
Stigg adds Airwallex billing, its first visible step beyond the Stripe ecosystem.
Stigg's newest release is a native Airwallex integration in beta, letting customers bill through Airwallex instead of Stripe. It follows the Stripe Projects listing, faster Plans and Add-ons, sub-10ms entitlement checks in the REST SDKs and a natural-language contracts AI skill. The runtime and the commercial layer are both growing.

◆ Current state
Purchasely is an SDK for managing in-app subscriptions and paywalls on iOS, Android, and web. SDK 6.0 modernized the initialization model, screen presentation, action handling, and purchase flow control across all platforms — a major version that breaks backwards compatibility but aligns the SDK with current platform requirements. SDK 6.1 builds on this with a web-to-app redemption flow and proxy routing for environments where the Purchasely API is unreachable.
◆ Where it's heading
The 5.x series added screen orchestration (Flows), conditional visibility (Bring Your Own Screen), web checkout parity, and campaign tooling. The 6.0 reset cleans up the resulting complexity. The web-to-app redemption feature in 6.1 extends the funnel across platforms — subscribers who start on the web can redeem in the app and vice versa. This is a meaningful cross-platform monetization capability.
◆ Prediction
The next move is likely expanding web-to-app funnel analytics and deepening the server-to-server event model to support more complex subscription lifecycle scenarios (pauses, downgrades, family plans). The proxy routing feature in 6.1 suggests Purchasely is serving markets or enterprise environments with restricted network access.
Stigg
5.0FINANCE
Stigg adds Airwallex billing, its first visible step beyond the Stripe ecosystem.
◆ Current state
Stigg's newest release is a native Airwallex integration in beta, letting customers bill through Airwallex instead of Stripe. It follows the Stripe Projects listing, faster Plans and Add-ons, sub-10ms entitlement checks in the REST SDKs and a natural-language contracts AI skill. The runtime and the commercial layer are both growing.
◆ Where it's heading
Stigg is positioning itself as the monetization layer that sits above whichever billing provider a company uses, while extending into sales-led contracts with AI-operable tooling. Distribution is widening at the same time: inside Stripe Projects for new developers, and toward Airwallex for companies that don't bill through Stripe.
◆ Prediction
Expect more billing-provider integrations and Contract Management leaving beta; the entries don't show which providers come next.
