Is Apache 2.0 compatible with GPL 3.0?
Apache 2.0-licensed code is compatible with a GPL 3.0 project. Here is what that means for your obligations, conflicts, and distribution.
The license of the code you want to use.
The license you are applying to your project.
The short answer
Permissive licenses like Apache 2.0 carry few restrictions, so they can be absorbed into copyleft projects like GPL 3.0.
Key obligations
Retain the original copyright notices and license text for the Apache 2.0 components.
Potential conflicts
None. The copyleft terms supersede the permissive terms for the combined work.
Distribution notes
The combined work as a whole must be distributed under GPL 3.0.
Deep-dive resources
Stop guessing. Start automating.
Modern applications pull in hundreds of transitive dependencies. A manual check can't keep up.

What this means in practice
Apache License 2.0 is a permissive (+ patent grant) license and GNU GPL v3.0 is a strong copyleft license. That combination is generally safe to ship: you can include the Apache 2.0 library in a GPL 3.0 project as long as you meet the notice and distribution requirements below. Internal-only use rarely triggers copyleft obligations, while shipping binaries or running a public network service is more likely to.
Compliance checklist for Apache 2.0 → GPL 3.0
- Retain the original Apache 2.0 copyright and license notices.
- Record that your project bundles Apache 2.0-licensed components (e.g. in an attribution or NOTICE file).
- Distribute the combined work under terms that satisfy GPL 3.0.
- Re-check the verdict if you switch to SaaS delivery or start modifying the component.
