Can I use gkd-kit/gkd commercially? What is its license and are there limitations?

The software gkd-kit/gkd is currently under the GPL-3.0 license, which is a strong copyleft license. This means that you cannot use it commercially; the project expressly states that it is intended for learning and communication only, prohibiting any commercial or illegal uses.

Key Details:

• Repository: gkd-kit/gkd
• Stars: 40,782
• Last Push: 1 day ago (Actively maintained)
• Contributors: 11
• Open Issues: 11
• Latest Release: v1.12.1 on May 20, 2026

License and Limitations:

• The GPL-3.0 license is designed to ensure that anyone can use, modify, and distribute the software, but any derivative work must also be open-sourced under the same license. Additionally, commercial use is explicitly prohibited.

Given these factors, if you are considering using gkd for commercial purposes, it would be prudent to explore alternatives or ensure that your use case aligns with the non-commercial stipulations of the license.

Recommendation: If you need a tool that allows for commercial use, look for projects under more permissive licenses (like MIT or Apache 2.0) instead of GPL-3.0.
