You can download and use all amCharts products for free. The only limitation of the free version is that a small amCharts logo will be displayed in the corner of your charts. If you’d rather have your charts without any branding, or you appreciate the software and would like to support its creators, please purchase a commercial license.
DISCLAIMER: The CDN resources are served through high-availability, load-balanced infrastructure. However amCharts does not provide any guarantees regarding uptime, availability and version consistency. It’s pretty reliable for production use, but if you need any to be extra cautious, use your own server infrastructure.
Also, CDN contains the latest released versions. This means that the version you use may be upgraded without your intervention. If you need to keep control on what version is used, use your own servers.
If you’d like to install amCharts 4 files right on your server, you can download these archives listed below.
