A side-by-side editorial comparison of LNbits and Purchasely — release velocity, themes, recent moves, and the top alternatives to consider.
LNbits v1.6.0 replaces Python extension security reviews with WASM sandboxing — a new distribution model for Lightning tools.
LNbits v1.6.0 shipped WASM extensions: sandboxed plugins that can be written and shared without requiring core-developer security review, directly addressing the bottleneck that limited ecosystem growth. Lightning Addresses moved from extension territory into core, and the block explorer via Electrum and Bark (barkd) funding source added new infrastructure options. v1.6.1 followed with phoenixd node page, NWC false-failure fixes, and payments CSV comment export — iterative polish on the 1.6.0 surface.
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 shifts security isolation from audit-based to runtime-sandbox-based, which should increase the throughput of the extension ecosystem considerably. Lightning Addresses as a core feature signals LNbits is moving toward being a complete Lightning wallet experience rather than just a developer toolkit. The multi-backend funding source expansion (Bark, Blink, phoenixd, LND gRPC self-payments) suggests LNbits is building toward being backend-agnostic across the Lightning node ecosystem.
WASM extension tooling will mature next — documentation, the vetted extension repository growing, and possibly browser-based WASM development support. Phoenixd's deepening integration (node page, preimage returns, mnemonic display) hints at a tighter mobile Lightning node story ahead.
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.
