Archived projects and projects with no commit in the last two years are left out. - Base score: GitHub stars on a log scale plus commits in the last 12 months (log scale, capped at 1,000). - Bonus points for a published Docker image, an OSI-approved open-source license and a commit in the last 90 days. - Each "Best for" section re-ranks the same apps with that audience's profile (for example startups add points for permissive licenses, project websites and recent commits; small business for Docker images and deploy guides). - Source-available apps can rank, but they are labelled and never described as open source. ## FAQ ### Is Odoo free?
