Giscus is a neat open source project that lets you add Github comments to your website.
abuses uses the discussions API from Github to store each message.
It has a lot of configurations you can do so consider giving them a ⭐️ for building an awesome product.
If you want to see a live demo check out my site. Feel free to drop a comment or reaction but keep things civil please 🙏.
If you are interested in how it was integrated into my next.js app check out the source code here.
