Invoice Ninja vs Purchasely: at a glance
What is Invoice Ninja?
Invoice Ninja adds OIDC auto-login while rebuilding its Stripe plumbing
Invoice Ninja ships v5.13 patch releases every few days. October's substance is payments and auth: Stripe moved to the 2025.basil API as a minimum with webhook upgrades, offline payment sync was finished, GoCardless, Razorpay and Braintree got fixes or upgrades, and OIDC gained auto-login and labelling. Several API fixes were found while building new mobile apps.
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.

Invoice Ninja

Invoice Ninja adds OIDC auto-login while rebuilding its Stripe plumbing
◆ Current state
Invoice Ninja ships v5.13 patch releases every few days. October's substance is payments and auth: Stripe moved to the 2025.basil API as a minimum with webhook upgrades, offline payment sync was finished, GoCardless, Razorpay and Braintree got fixes or upgrades, and OIDC gained auto-login and labelling. Several API fixes were found while building new mobile apps.
◆ Where it's heading
The work points at two things: keeping the payment gateway layer current with providers' API versions, and preparing the backend for new client apps. European e-invoicing (ZUGFeRD/CII, EPC QR codes) also keeps getting attention.
◆ Prediction
Expect more API fixes tied to the new apps and further gateway updates; whether the apps themselves appear in this feed is unclear.

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.
