There are two kinds of mastofeeds?! Some notes and ideas.
Posted by jpluimers on 2026/10/21
Earlier this year, someone mentioned Mastofeed. Then I found there are two kinds of Mastofeeds. Both have their own domain and their own repository. Both are free, so I wonder what their business models are as something or somebody needs to be the product. Both have to do with feeds and the ActivityPub protocol of the Fediverse (which mainly consists of Mastodon servers, but other types of servers are still growing). Both can be self-hosted. Both their directions and audience differs.
In short:
- mastofeed.org (mentioned to me first) is uses RSS as feed and posts entries to the Fediverse
- mastofeed.com (found later) uses Fediverse as feed and exposes entries as an HTML iframe using an HTTP API
Some more links:
Mastofeed.org
Runs in the EU since 2022. Signing up requires write access to your ActivityPub feed.

If you sign up with MastoFeed to your Mastodon server, said server will grant MastoFeed a private key for MastoFeed to post on your account. This uses the OAuth 2.0 Protocol.
MastoFeed only asks for the following permissions: Read-only access to your account (to get your username), write-only access to your posts (to send public messages on behalf of your account), and write-only access for media attachments (to include pictures in the messages if necessary).

MastoFeed is the easiest way to automate sending your RSS Feeds to your Mastodon account.

Personally, I don’t need this as WordPress solved it by posting it to both @wiert@mastodon.social and @wiert.me@wiert.me
Mastofdeed.com
On-line since 2018; seems hosted in the USA.

If you wanted to make high-impact fediverse software, I would recommend making a simple daemon that does the following:
– Consumes RSS/Atom feeds
– Posts them as subscribable feeds over activitypub
– So dead easy you can host it yourself as a simple daemon on your server
– Optionally: collects replies as a comment section with a way to render them inline, a-la disqus, with some simple moderation tools. Simplest way to reduce spam would be to make it approve-only to show up on the feed.You could extend this to allow posting on other servers etc. But, in other words, let more people use the static site generator they already have

@cwebber I haven’t audited the source code yet but I’ve seen some accounts using mastofeed

@Christine Lemmer-Webber I’m using friendica which does more or less that (among a thousand other features, of course), and I can confirm it’s something that would be really useful
especially if it was something easy to package for distributions, and thus easy to run in a sensible and low effort way
The idea here is to actually combine mastofeed.org, mastofeed.com and extend bits of the the masto-feed below. Interesting concept!

It is a pity though, as it is an interesting concept: it can communicate two ways so in addition to publishing over ActivityPub, it can also respond to ActivityPub messages for status and updates. In a sense it reminds me of the old BITNET Relay, LISTSERV and TRICKLE days.

- Friendica might do what all the above already does:
