Self-hostable software: Copyleft License (692)
Projects with copyleft licenses require that derivative works are distributed under the same or compatible license terms. This ensures that improvements and modifications remain freely available to the community.
Common copyleft licenses include GPL 3.0, AGPL 3.0, LGPL 3.0, and MPL 2.0.
Copyleft licenses vary in strength: strong copyleft (GPL, AGPL) requires the entire derivative work to use the same license, while weak copyleft (LGPL, MPL) only requires changes to the licensed files themselves to be shared.
