Microsub
Microsub provides a standardized way for reader apps to interact with feeds. By splitting feed parsing and displaying posts into separate parts, a reader app can focus on presenting posts to the user instead of also having to parse feeds. A Microsub server manages the list of people you're following and collects their posts, and a Microsub app shows the posts to the user by fetching them from the server.
- Want to implement a Microsub client or server? See the Microsub specification.
Contents
Microsub enables a client to show posts from feeds across the web and display them in a reader, without having to do any feed parsing itself. With Microsub, people can use any suitable reader to follow and read the content. Decoupling the idea of displaying posts from actually fetching remote feeds makes it simpler to build a reader, as well as makes your subscription list portable between readers.
Reader apps can also use Micropub to respond to content the user is following, for example with a like, a repost or a comment.
Microsub decouples managing subscriptions and delivering content from the presentation of that content. The Microsub server handles the actual subscription to feeds, (likely using WebSub), while providing a consistent API so that apps can present the contents of the feeds in a reader interface.
A short verbal discussion of what it does can be heard here on

Clients
Indigenous
Indigenous is a set of in-development native iOS and Android Microsub reader apps.
Android
Indigenous for Android is a native Android Microsub reader app built by
Kristof De Jaeger
Monocle
Monocle is a Microsub reader web app built by
Aaron Parecki. If you have a Microsub server, you can use the hosted version at https://monocle.p3k.io
Together
Together a web based Microsub reader, primarily developed by
Grant Richmond. Source code at https://github.com/alltogethernow/web/ and an online at https://alltogethernow.io
Ekster Reader
Ekster Reader is an in-development Microsub reader, running in a browser. It connects directly to a Microsub server without its own Microsub proxy backend. For this to work you do need a Microsub server that handles CORS headers, to allow access from the browser. This also applies for the Indieauth endpoint. A version is hosted at https://reader.p83.nl/
Microsub Notifier
microsub notifier is a Microsub client built purely to send notifications of new content in any of your Microsub channels. Built by
Grant Richmond is is hosted at https://microsub-notifier.tpxl.io
(needs screenshots!)
Servers
- Aperture, built by
Aaron Parecki, is a Microsub server with no UI for rendering posts. This is intended to be a server only, and all rendering happens using Microsub clients. It is built in PHP with MySQL storage. Source on Github - The Drupal IndieWeb module, built by
Kristof De Jaeger includes a built-in Microsub server. - dobrado includes a Microsub server, built by
Malcolm Blaney - Micro.blog can be used as a Microsub server. Channels are mapped to the built-in sections of Micro.blog like Timeline, Mentions, and Favorites.
- Yarns is a plugin to run a Microsub server from your WordPress site, built by
Jack Jamieson. It uses the Parse This library built by
David Shanske. It has a UI for managing channels and subscriptions. - Ekster, built by
Peter Stuifzand, is a Microsub server in Go using a Redis storage. Source on Github
Proxies - not entire server(s), but implements Microsub server API wrapped around existing service(s):
- Baffle, built by
Ryan Barrett, is a bridge that makes traditional feed readers like NewsBlur and Feedly support Microsub. More background
IndieWeb Examples
-
Aaron Parecki uses Aperture as his Microsub server, and the Together and Indigenous clients.
-
Eddie Hinkle uses a self-hosted Aperture as his Microsub server, and the Indigenous for iOS (mobile) and Monocle (on computer) clients.
-
Marty McGuire uses an identical setup since 2018-03-05.
-
-
Kristof De Jaeger uses the built-in Microsub server of the Drupal Indieweb module and the Indigenous for Android (mobile) and Monocle (on computer) clients -
Neil Mather uses an account on
Aaron Parecki's Aperture instance and the Indigenous for Android (mobile) and Monocle (on computer) clients since 2018-09-07 -
Peter Stuifzand uses Monocle, Indigenous, Together and Ekster Reader with his own microsub-server, Ekster. - Add yourself here… (see this for more details)
In Progress
- Sven Knebel is building a bridge from Inoreader to Microsub (not ready yet, sorry!)
-
Jack Jamieson is building a WordPress plugin called Yarns Microsub Server. Source on Github
-
Sebastiaan Andeweg is working on a project codenamed Leesmap, as described on this post on Seblog.nl

Getting Started
To use a Microsub app, your website will need to support IndieAuth and advertise a Microsub endpoint. Starting with a plain HTML home page, the steps below will walk you through getting set up so you can log in to an IndieWeb reader app.
Setting up IndieAuth
If you have WordPress or another website that has native IndieAuth support, that is your best option. Install the IndieAuth plugin in WordPress or your CMS.
If you are not using a CMS that has native IndieAuth support, you can use the steps below to delegate all the authentication to external services so that you can use it with a static site or any other project.
- add a rel=me link to your GitHub profile
- e.g.
<a href="https://github.com/username" rel="me">username</a> on github
- e.g.
- add the following tags to delegate your IndieAuth handling to indieauth.com
-
<link rel="authorization_endpoint" href="https://indieauth.com/auth"> -
<link rel="token_endpoint" href="https://tokens.indieauth.com/token">
-
Setting up Microsub
- sign in to https://aperture.p3k.io/login with your domain
- after you sign in you will see a link tag displayed on your dashboard
- add the <link> tag it generates for you to your web page
- e.g.
<link rel="microsub" href="https://aperture.p3k.io/microsub/000">
- e.g.
- sign in to an IndieWeb reader!
