This is really cool. I'm wondering if people are using BS4 in production? I recently used BS3 because I saw that 4 was still in Alpha. Is it safe to use in production even though it's in alpha state?
I'm using it in prod for a site with roughly 200k request per minute. It has been great. We were on bootstrap 2 and doing significant changes where upgrading Bootstrap made sense. We've been live with it since December.
