Matomo and Piwik

Hi I am a little confused about Matomo and Piwik
After some tests and seems to me, that Piwik is better, more user-friendly and free
Will Piwik continue to work, is it safe to use it or need to migrate to Matomo?

Thank you

We have big plans when it comes to the future, so no need to worry. The product will remain free for 500k events/month. From my perspective, there’s no need to migrate to Matomo, unless you have some really specific requirements.
