Brutaldon is a brutalist, Web 1.0 web interface for Mastodon. It is not a Mastodon-compatible social networking server; rather, it is just a client, like the Android or iOS client for Mastodon you may already be using, but it runs in a web server, and is accessed through a web browser. The web browser that brutaldon targets is Lynx. Of course, you can use it in a more heavy-weight graphical browser, as well as other text browsers such as w3m or elinks. There is a hosted instance at brutaldon.online which you can use to log in to any instance. However, you are also encouraged to run your own, either locally or on a public server.
