Health score combines commit recency, twelve-month commit volume, months with activity, release recency and archive state. Metadata refreshed August 2026.
Source-available (BSL, SSPL, Commons Clause): readable but not open source. Commercial use is usually restricted — read the licence before building on it.
This matters most when you plan to sell a hosted version. A permissive licence means anyone — including a competitor with more capital — can do the same, so your defensibility has to come from distribution, support or data, not from the code.
Invoice Ninja is shipping code consistently, so a buyer comparing your product will find a maintained free option. Price and position against the total cost of self-hosting it, not against the paid incumbent's list price.
Assume every prospect can find a free version in five minutes. Your wedge has to be something open source structurally cannot deliver: compliance, support SLAs, managed hosting at scale, or a workflow the maintainers refuse to build.
Actively maintained. Invoice Ninja recorded 1903 commits over the last twelve months, with activity in 12 of those months and 373 commits in the last quarter. Last commit: 2026-08-11. Last release: 2026-08-15. Committed within the last 45 days.

Invoice Ninja targets the same job as Invoicing and is actively shipping. Adoption sits at 10.0k stars. Whether it is a good replacement depends on your deployment constraints: self-hosting adds infrastructure, upgrade and security work that a commercial subscription absorbs for you.
42 open-source implementations, 27 of them actively maintained, led by HyperSwitch at 43k stars. Saturation score 72/100 — Crowded. Free, maintained alternatives already dominate this category.
