Strong copyleft

GNU General Public License v3.0

Strong copyleft requiring that distributed derivatives remain under GPL-compatible terms with corresponding source.

Compared to common options: Stronger than MIT/Apache/MPL for distributed works; AGPL is stricter for network services; GPL-2.0 is the older generation.

Generally allows

  • Commercial use
  • Modification
  • Distribution
  • Patent use
  • Private use

Typically requires

  • Disclose source when you distribute the software
  • Include license and copyright notices
  • State changes
  • Use a GPL-compatible license for distributed derivatives

Watch-outs

  • Distributing proprietary closed derivatives of GPL-covered works
  • Holding authors liable

How teams usually use it

  1. Prefer when you want improvements shared back with the community on distribution.
  2. SaaS-only use without distribution may not trigger GPL release duties — AGPL is stricter for network use.
  3. Check dependency compatibility before combining GPL code with incompatible licenses.

Orientation only — not legal advice. Always verify the repository LICENSE file, notices, and dependency terms, and obtain counsel for commercial distribution decisions.
