How it works

  1. Add your site and paste two lines of HTML into your page head.
  2. Paste the snippet into your site. Once it shows up on your homepage, the site is verified.
  3. Connect Bluesky or Mastodon. Add your feed URL if you also want to send mentions.

Receive

Incoming mentions arrive at your endpoint. You decide who gets through: allow all, deny all, or approve by hand. A JSON API serves them as a JF2 feed.

Backfeed

Connect Bluesky or Mastodon. Replies, likes and reposts become mentions on the matching blog post.

Send

Add your feed URL. Each new post that links to another site sends that site a webmention.
