I’m considering different comment system. I found this really useful list of options, but it’s 5 years old so I don’t know if it’s still up to date. I would like another “integrated third party” system preferably. My main priority is to choose a service which is reliable and likely to stay open (I know, this is the one reason to choose Disqus normally !).
I use Hashover in version 2.0. It is a bit buggy in some places, the author himself writes that on his website. Version 1.0 has been around for 10 years. On the whole I am satisfied and it is free. The integration into the own design and the adaptations for a multilingual website works. Have written a blog article about it - https://tekki-tipps.de/en/integrate-hashover-2.0-comments-in-hugo-websites/
I few month back I tried for days. Installation typically failed somewhere, depends what guide I followed. After a week and hours of trying it was not running. It’s much deeper than what they write on the Isso site. I always tried on a brand new free VPS (I had this link to a service that one can use for 3 days for free)
Then after a while I manage to set up one in Docker. But there is no instruction how make it run with several websites, or how to get old comments into the DB.
This said, Hashover looks very good! @myFrank-wk, great guide! Will need to have a closer look. Looks easier to implement. The MySQL backend would make it very easy to feed in old comments.
