Invoice Ninja vs Adapty

Invoice Ninja vs Adapty: 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 Adapty?
Adapty lets one paywall flow personalise itself with the app's own user data
Adapty has finished moving customers onto one builder: the old Paywall and Onboarding Builders were deprecated on October 1 and Paywalls now live inside Flows & Paywalls. Since then it added a yearly plan sold as 12 monthly payments on native iOS, and the November 9 roundup brings custom tags, where the app passes a value through the SDK and any text in a flow can display it, alongside flow funnels and screen animations.

Invoice Ninja
5.0FINANCE
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.
Adapty
5.0FINANCE
Adapty lets one paywall flow personalise itself with the app's own user data
◆ Current state
Adapty has finished moving customers onto one builder: the old Paywall and Onboarding Builders were deprecated on October 1 and Paywalls now live inside Flows & Paywalls. Since then it added a yearly plan sold as 12 monthly payments on native iOS, and the November 9 roundup brings custom tags, where the app passes a value through the SDK and any text in a flow can display it, alongside flow funnels and screen animations.
◆ Where it's heading
With the migration done, the work has moved to making each flow do more: personalised copy, funnel analytics on flows, and animation. Adapty is turning the paywall builder into a general onboarding and conversion surface, with agent-built flows from August and pricing experiments like the 12-payment yearly plan layered on top.
◆ Prediction
Expect more SDK-fed personalisation and per-screen analytics inside flows, and the 12-payment yearly plan to extend beyond native iOS; the entries give no timeline for either.
