Is GPL 2.0 compatible with MIT?
GPL 2.0-licensed code is not compatible with a MIT 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
GPL 2.0 is a copyleft license — any combined work must keep that copyleft license, so you cannot wrap it in a permissive license like MIT.
Key obligations
Adopt GPL 2.0 for the whole project to use this code.
Potential conflicts
Copyleft requires derivative works to be released under the same terms.
Distribution notes
Prohibited under MIT.

Stop guessing. Start automating.
Modern applications pull in hundreds of transitive dependencies. A manual check can't keep up.

What this means in practice
GNU GPL v2.0 (Only) is a strong copyleft license and MIT License is a permissive license. Combining them in a single distributed work is not permitted because their terms conflict. You can often still use the GPL 2.0 component if you keep it at arm's length — behind a separate process or network boundary — or by choosing an alternatively-licensed dependency.
Compliance checklist for GPL 2.0 → MIT
- Do not combine GPL 2.0 and MIT code in the same distributed binary.
- Isolate the GPL 2.0 component behind a process or network boundary if you must use it.
- Evaluate an alternatively-licensed library, or re-license your project to resolve the conflict.
- Get legal sign-off before shipping anything that links the two.
About these licenses
GNU GPL v2.0 (Only)
LibraryStrong copyleft. Distributing a combined work means releasing all of it under GPL v2.0. The "only" variant is incompatible with the GPL v3 family.
- Type
- Strong copyleft
- Patent grant
- None
- Source sharing
- Entire combined work
MIT License
ProjectA short, highly permissive license. Use it almost anywhere as long as you keep the copyright and license notice.
- Type
- Permissive
- Patent grant
- None
- Source sharing
- Not required
GPL 2.0 and MIT: frequently asked questions
Common questions about combining GNU GPL v2.0 (Only) and MIT License.
Is GPL 2.0 compatible with MIT?
GPL 2.0 is a copyleft license — any combined work must keep that copyleft license, so you cannot wrap it in a permissive license like MIT.
Can I use GPL 2.0 code in a MIT SaaS or cloud application?
Over SaaS, traditional copyleft licenses like GPL 2.0 often do not trigger their share-alike requirements (the "SaaS loophole"). This is legally complex and only conditionally compatible.
What are my obligations when combining GPL 2.0 and MIT?
Adopt GPL 2.0 for the whole project to use this code. Prohibited under MIT.
