Hey, I'v used Repl.it a fair amount for Python in the past. Seems like you've built a really nice tool which has lots of languages supported. Out of curiosity, how are you funded?
Was a side project in hibernation that didn't cost anything to run. Around 2015 we revamped the site and added a lot of features which caused us to grow a lot and became too expensive to run and maintain. Quit my job last year and raised a seed round but still try to keep burn rate to a minimum and hope to start making money soon.
