Hello, I built an embedded commenting system for Jekyll (and others), called Talkyard. It’s open source. And there’s hosting, so you can use it without any server.
Here’s a Jekyll site with getting-started instructions, and you can post test comments:
What are your thoughts? Feedback is welcome :- ) Any reason you would hesitate to use it? Or what do you like about it? If you want to use it and / or have questions, I’d be happy to help.
Talkyard is forum software too (see https://www.talkyard.io) so you can create e.g. a community at
forum.yourwebsite.com that integrates with the Jekyll blog comments.
