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.
Stump 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.
