You’ve probably heard a lot of hype around one of the newest kids on the framework block, Remix. It may be surprising that it got its start back in 2019, but it was originally only available as a subscription-based premium framework. In 2021, the founders raised seed funding and open sourced the framework to let users start using Remix for free. The floodgates opened and everyone seems to be talki
