So, unless you have access to some non-public information, codesandbox (repo started in Nov 2016) is significantly older than stackblitz (repo started in July 2017). Personally, I'm suspicious that stackblitz is simply a proprietary copy of the open source codesandbox (not that stackblitz doesn't bring it's own innovations to the table).

I also learned about stackblitz before codesandbox (via Angular), and incorrectly thought that codesandbox was copying stackblitz.
