What is Lemon Squeezy?

Lemon Squeezy's public changelog has been visibly idle for roughly nine months. The last shipped work centered on payment-platform fundamentals: 34-language checkout localization with no configuration required, MRR/ARR chart accuracy improvements, manual webhook simulation for developer integration, account-level 2FA, and partial refunds with credit notes.

What is Invoice Ninja?

Invoice Ninja ships a frequent GitHub release train for its open-source invoicing platform. The cadence is fix-and-feature point releases: passkey login, global tags across entities, PHP 8.5 support, ZUGFeRD and SwissQR e-invoicing work, and QuickBooks sync improvements, interleaved with dependency bumps and bug fixes.

Lemon Squeezy vs Invoice Ninja: editorial side-by-side

L0.0

Lemon Squeezy ships fundamentals — localization, charts, webhook tooling — then goes quiet.

◆ Current state

Lemon Squeezy's public changelog has been visibly idle for roughly nine months. The last shipped work centered on payment-platform fundamentals: 34-language checkout localization with no configuration required, MRR/ARR chart accuracy improvements, manual webhook simulation for developer integration, account-level 2FA, and partial refunds with credit notes.

◆ Where it's heading

The arc through 2024 and into mid-2025 was filling out merchant-of-record table stakes — international checkout, refund flexibility, security, integration ergonomics. Since then, the public surface has gone silent. That can mean a deliberate move toward larger less-frequent releases, focus on the parent company's roadmap (Stripe acquisition era), or genuine reduced cadence. The entries themselves don't disambiguate.

◆ Prediction

The next public update is unclear from the visible signal. If shipping resumes, the most natural extensions of the prior trajectory are subscription dunning workflows or richer tax/VAT automation atop the localized checkout.

I5.0

Invoice Ninja's point-release train adds passkeys and global tags amid steady fixes

◆ Current state

Invoice Ninja ships a frequent GitHub release train for its open-source invoicing platform. The cadence is fix-and-feature point releases: passkey login, global tags across entities, PHP 8.5 support, ZUGFeRD and SwissQR e-invoicing work, and QuickBooks sync improvements, interleaved with dependency bumps and bug fixes.

◆ Where it's heading

The product is steadily broadening payments, e-invoicing compliance (ZUGFeRD, SwissQR), and accounting integrations (QuickBooks) while modernizing auth (passkeys) and the API (filters, sorting, tags). It is incremental maintenance and breadth, not a directional shift — a mature OSS tool thickening its feature surface release by release.

◆ Prediction

Expect continued e-invoicing format coverage, payment-gateway additions, and API refinements on the same rapid point-release cadence.
