pyqt5 safe for commercial use?PyPI package · License: GPL-v3
pyqt5 is licensed under GPL-v3. That triggers obligations in 3 of the 5 common shipping models, so whether it is safe for you depends on how you ship.
| How you ship it | Result | Why |
|---|---|---|
| Hosted SaaS | No obligation | GPL-v3 triggers its obligations on distribution. Your distribution model is hosted SaaS, which is not distribution, so no obligation arises today. Shipping this software later — on-premises delivery, a binary, or a published library — would trigger whole-work source disclosure. |
| Distributed binary / app | Obligation triggered | GPL-v3 requires that a work incorporating it, when distributed, be licensed as a whole under the same terms with corresponding source made available. Your distribution model is distributed binary or application, which triggers that obligation. |
| Delivered to customer | Obligation triggered | GPL-v3 requires that a work incorporating it, when distributed, be licensed as a whole under the same terms with corresponding source made available. Your distribution model is software delivered to a customer environment, which triggers that obligation. |
| Internal use only | No obligation | GPL-v3 triggers its obligations on distribution. Your distribution model is internal use only, which is not distribution, so no obligation arises today. Shipping this software later — on-premises delivery, a binary, or a published library — would trigger whole-work source disclosure. |
| Published library | Obligation triggered | GPL-v3 requires that a work incorporating it, when distributed, be licensed as a whole under the same terms with corresponding source made available. Your distribution model is a published library, which triggers that obligation. |

If you only use it at build time, the answer changes.
GPL-v3 appears as a dev dependency, so it is not part of the artifact you ship. Distribution-triggered obligations do not arise. Tools that emit code into your output, such as code generators, are a separate case worth checking individually.
