About these numbers. Stars, dates and licenses come from GitHub through ecosyste.ms, collected on 10 Nov 2026; they can lag GitHub by a few days. A project is listed only if it has 300 or more stars, was updated in the last 12 months and states a license. A listing is not an endorsement, and we have not tested these tools on Antideploy yet. Logos belong to their projects and companies and are shown only to say which is which.
