μpub
micro social network, federated
μpub aims to be a private, lightweight, modular and secure ActivityPub server
- follow development in the dedicated matrix room
μpub is usable as a very simple ActivityPub project: it has a home and server timeline, it allows to browse threads, star notes and leave replies, it renders remote media of any kind and can be used to browse and follow remote users
all interactions happen with ActivityPub's client-server methods (basically POST your activities to your outbox), with appropriate extensions: μpub doesn't want to invent another API!
development is still active, so expect more stuff to come! since most fediverse software uses Mastodon's API, μpub plans to implement it as an optional feature, becoming eventually compatible with most existing frontends and mobile applications, but focus right now is on producing something specific to μpub needs
a test instance is usually available at feditest.alemi.dev
about security
most activitypub implementations don't really validate fetches: knowing an activity/object id will allow anyone to resolve it on most fedi software. this is of course unacceptable: "security through obscurity" just doesn't work
μpub correctly and rigorously implements and enforces access control on each object based on its addressing
most instances will have "authorized fetch" which kind of makes the issue less bad, but anyone can host an actor, have any server download their pubkey and then start fetching
μpub may be considered to have "authorized fetch" permanently on, except it depends on each post:
- all posts marked public (meaning, addressed to "https://www.w3.org/ns/activitystreams#Public"), will be fetchable without any authorization
- all posts not public will require explicit addressing and authentication: for example if post A is addressed to example.net/actor
- anonymous fetchers will receive 404 on GET /posts/A
- local users must authenticate and will be given said post only if it's addressed to them
- remote servers will be given access to all posts from any of their users once they have authenticated themselves (with http signing)
note that followers get expanded: addressing to example.net/actor/followers will address to anyone following actor that the server knows of, at that time
contributing
all help is extremely welcome! if my cgit looks too scary there's a github mirror you can open issues or PRs on. get in touch with me (fedi is fine, but a mail works too), i'd be thrilled to showcase the project to you!

what about the name?
μpub (or simply upub) means "micro-pub", but could also be read "upub", "you-pub" or "mu-pub"
