With now you can alias your deployments to a better URL, in the free tier you can alias to now.sh sub domains (eg. coolproject.now.sh), if you paid you can use a custom domain but I think for OSS projects (free tier) a now.sh sub domain it's OK
Definitely good to know about the subdomain aliases. I like to use now for prototypes that I can easily share with others, so that will come in handy!
For my personal site, I wanted to use evansalter.com for the domain, so that wouldn't have worked for me unless I wanted to pay. I definitely haven't ruled out now for other types of projects though, as I do like what the service offers. Thanks for the tip!
