Health score combines commit recency, twelve-month commit volume, months with activity, release recency and archive state. Metadata refreshed August 2026.
Permissive (MIT, Apache, BSD): you can fork it, close the source and sell it. Lowest legal friction for a commercial product.
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.
Gollum is not currently shipping at a healthy pace. Popular but stalled projects inflate how competitive a category looks — and they are also risky to build on.
Winnable, but differentiation is not optional. Pick one underserved segment and be visibly better for it rather than competing feature-for-feature with a free tool.
