Invoice Ninja vs Firefly III: 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 Firefly III?
Firefly III keeps tagging develop builds daily, still with no release notes.
Firefly III's feed remains automated develop pre-releases. November 12 and 13 added two more develop tags and another boilerplate development release, on top of four on November 12 alone. None includes a changelog.

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.
Firefly III
5.0FINANCE
Firefly III keeps tagging develop builds daily, still with no release notes.
◆ Current state
Firefly III's feed remains automated develop pre-releases. November 12 and 13 added two more develop tags and another boilerplate development release, on top of four on November 12 alone. None includes a changelog.
◆ Where it's heading
The project is in a pre-release stretch where builds ship several times a day without notes. The feed shows activity but not what is changing.
◆ Prediction
The feed does not show what the next stable release will contain; a tagged version with a changelog is the next thing worth watching.
