Colanode is an open-source groupware project, with 5.0k GitHub stars and a health score of 30/100. It committed 74 times in the last twelve months across 6 of those months, and its status is slowing down. Licence: Apache-2.0. It does not currently meet the momentum threshold, so verify maintenance before depending on it.

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.
Colanode 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.
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.
