Authlib Under BSD License

Happy new year, happy new license. Authlib will be licensed under BSD instead of AGPL starting from next release v0.11.

The new year has arrived, it is the time to make a change. The license issue of Authlib has been there for a long time, AGPL seems not a good choice in first place. Although I had planned to split Authlib into 3 modules and issue them under different licenses, that won't happen in a short time. AGPL is preventing many people from using Authlib, the situation will end soon. New year is the time to change the license, and I'm happy to announce that Authlib is going to be licensed under BSD from next release.


Authlib was created to replace my Flask-OAuthlib project. In my previous blog article Announcement of Authlib, the following is posted:

That is why I started Authlib from scratch and build it as a monolithic project. Starting from scratching would provide Authlib a cleaner and better designed code base, it won't be affected by the maintenance of other projects. Being monolithic would keep specification implementation and framework integrations synchronic in Authlib, and it would also provide a better API design for integrations.


The original goal of making Authlib sustainable won't change. Being profitable equals being sustainable. Although I had switched Authlib license from AGPL to BSD, it is still suggested that enterprise users buy a commercial plan.

  1. You will be enlisted in the security mail list to get security notification at first time;
  2. Your feedbacks will get responses more quickly than community support;
  3. There will be more features in the future.

There is also another way to support my work on Authlib. I'm now accepting donations and sponsorships on Patreon. Thanks for supporting my work on Authlib.
