Is pyqt6 safe for commercial use?

PyPI package · License: GPL-3.0-only

pyqt6 is licensed under GPL-3.0-only. That triggers obligations in 3 of the 5 common shipping models, so whether it is safe for you depends on how you ship.

Can I use pyqt6 in SaaS, a distributed app, or internally?

How you ship itResultWhy
Hosted SaaS No obligation GPL-3.0-only 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-3.0-only 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-3.0-only 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-3.0-only 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-3.0-only 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.

What obligations does pyqt6 carry?

Source disclosureSame license

If you only use it at build time, the answer changes.

GPL-3.0-only 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.

What is GPL-3.0-only?

Strong copyleft, with added anti-tivoization and patent-retaliation terms over v2. Like v2, its obligations attach to distribution, not to operating a hosted service.

How was this determined?

The license was read from the PyPI registry, then evaluated against each shipping model. Only the declared license is considered; code copied into a project's own source files is not detected by this method.
