Based on this it seems like Optimizely is extending free licenses for up-to 6 months

You may want to reach out to Optimizely support representative who can assist you better.
You don't need a license for learning Optimizely, you can download code from GITHUB and use Visual Studio to start coding including building the website. There are pre-built Optimizely fake branded websites such as foundation, alloy etc that you can build on top of and customize it for your client.
Hi, I'm currently creating a website for a humanistic project here in mexico and currently I'm exploring options for free cms solutions, but I would like to continue my learning on Optimizely (2 years of professional experience now) and use it for this. Please let me know if theres is a free limited version (or a more affordable one) or licenses for a non-profit organization.
Regards,
