A side-by-side editorial comparison of LNbits and Purchasely — release velocity, themes, recent moves, and the top alternatives to consider.
LNbits ships sandboxed WASM extensions, opening self-hosted Lightning wallets to uncurated plugins.
LNbits v1.6.0 was the project's most architecturally significant release: sandboxed WASM extensions let anyone write and share plugins without core-developer security review, addressing the bottleneck that kept third-party contributions slow. The same release shipped native Lightning Addresses in wallet core, an Electrum-backed block explorer, and Bark funding source support. v1.6.1 and v1.6.2 have since patched a PostgreSQL backup regression and closed NWC payment-failure false positives.
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.

The WASM extension model is a deliberate shift from curated gallery to permissive, sandbox-first plugin ecosystem — LNbits is betting that sandboxing replaces curation as the trust mechanism. Alongside that, native Lightning Addresses and payment breakdowns push the product further up the stack, adding first-class wallet UX that previously required an extension. LNbits is moving from infrastructure toolkit toward a more complete, self-sovereign financial application.
The next likely move is expanding the WASM sandbox API surface — more core hooks exposed to extensions, tooling improvements for the WASM manifest format, and a community-driven extension registry that can grow without gating on core-team review.
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.
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.
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.
