Add custom domains to your site, even if your hosting provider doesn't support them.
Get that little green lock next to your domain name. Let us worry about retrieving and renewing SSL certs from Let's Encrypt for you.
Get the most out of your domain by forwarding paths to different locations.
Route / to your landing page, /api to your API servers, /blog to your blog host.
Messing with config files and deployments is a pain. Set up your routes with a couple of clicks! Your changes will be available immediately.
Because your time is better spent working on your site, not your reverse proxy.
