A comments section is a great way to build a community for your blog. Recently when I started blogging, I thought of adding a comments section. However, it wasn’t easy. Hosted comments systems, such as Disqus and Commento, come with their own set of problems: They own your data. They are not free. You cannot customize them much. So, I decided to build my own comments system. Firebase seemed like a perfect hosting alternative to running a back-end server.
