April 23, 2017 supports several formats and protocols pioneered by the IndieWebCamp. We also believe in many of the same principles — that owning your content matters, and that you should post to your own site first before cross-posting or replying on other social networks.

Micropub: for iOS can post to Micropub-compatible sites. The server also supports the Micropub API for posting from other clients like Quill. See posting APIs for details.

Webmention: Replies in are sent as Webmentions to the target site if it supports Webmention. There is also limited support for receiving mentions from external blogs when they link to blogs.

Microformats: All hosted microblogs are marked up with Microformats. See the feeds page for details.

WebSub: can subscribe to blogs using WebSub to receive real-time notifications for when a blog post is published.
