Squarespace is awesome, but until they offer SSL certificates I can't recommend it to anyone. This is very unfortunate because it's a great product otherwise.
I've personally wanted seamless SSL for all Squarespace customers on custom domains for forever now, and we've put a lot of work into making it a reality. Furthermore, before initiatives like Let's Encrypt, the business/logistics side of getting this in place was a mess.
This is great! I really like Squarespace but this is one of the big features I have been waiting on. The other one is integrated A/B testing, or at least an easy way to work with A/B testing frameworks. Are there any plans to support this?
Not "seamless", but if you set up a VPS as a reverse proxy to your site with NGINX and Certbot, you can get Let's Encrypt running with Squarespace today. Doesn't require a huge amount of technical know-how; it was only the second SSL cert I'd ever installed. If anyone is interested in detailed instructions, shoot me an email.
