Open Source Charts

i want to talk about what kind of public depositories are available containing open source charts. There's just so many. Most of the major companies that i found, many of em, you know, micro soft included, and amazon,. they'll have charts out there that are public to install software. And all this is all in open source. I'm not familiar with people doing widely distributed proprietary charts. They're making all of these things where they want people to consume and run their software open source as far as the charts go.
