Interesting it's open-source but they don't seem to highlight it on their home page, I had to search for their Github page to find it https://github.com/tremorlabs/tremor
Then when I came back to the home page and searched for "license", I confirmed it says "Apache-2.0 license" in light-grey, small font in the middle of the page.
Hi, Chris here from Tremor. Many thanks for the feedback! I wasn't aware that it is not directly understood as an open-source library by our website hero title
I totally missed it as well, got to the bottom of the page, saw something about pre-release and assumed it was paid for. This comment above is what has made me go back and bookmark.
