Corteza is an open-source customer relationship management (crm) project, with 2.1k GitHub stars and a health score of 54/100. It committed 278 times in the last twelve months across 10 of those months, and its status is actively maintained. 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.
Corteza 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.
