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.
Cosmos 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.
The clearest opening in the dataset. Low open-source competition usually means either a genuinely underserved need or a market too small to attract volunteers — validate demand before assuming the former.
