About Hatsu
Hatsu is a free, open-source bridge that brings your static site to the Fediverse. Self-hosted and written in Rust, it uses your site's JSON, Atom or RSS feed to create Fediverse accounts and posts automatically: people on Mastodon and similar software can follow your site, discover new posts and reply, with replies fed back to you. Once configured it runs fully automatically. Hatsu suits bloggers and static-site owners who want Fediverse presence without running a full social server.
