<![CDATA[Reflecting on the existence of httpsig.org]]>httpsig.org is a site with one sole purpose, to advocate for the adoption of RFC 9421 HTTP Signatures. It has a "Libraries" tab that does exactly what it advertises, it lists a bunch of libraries for you to use so you don't have to roll your own.

If you want to integrate AP today, but you don't want to roll your own everything, where do you go? Who do you ask?

All I know is:

Do we even have a list sorted by language? This would be huge. What other AP frameworks do you know of?

Granted, I didn't do a lot of thinking and deep diving before I listed those two examples, but even then, that's 1 more example than is listed on https://activitypub.rocks, so I think I might be on to something here from a developer advocacy point of view.

If I were looking to integrate AP, one of the first conclusions I'd come to is that the protocol itself is fairly complex and a library or framework might help.

I don't think there is a list that plainly lists supported libraries by language.

I'll put out a blog post / update here when it is ready for other folks to try out

Yes, indeed. I found this the other day, and have queued it up for inclusion at https://delightful.coding.social/delightful-fediverse-development

I also found the ongoing work on the implementation, which is mighty interesting. Great work. Also queued up, but for inclusion at https://delightful.coding.social/delightful-fediverse-experience

What other AP frameworks do you know of?

This one is used in Mitra and all my other projects: https://docs.rs/apx_sdk/latest/apx_sdk/

There are many libraries, actually - the Delightful List has already been mentioned in this thread. But most of these libraries are not actively developed, or not used in any serious project.

So I've been thinking of adding a curated list of libraries to the ActivityPub developer guide.

@tom @julian@activitypub.space
It'll be a bit, yeah, and ours is going to be a bit opinionated, I want to push for portable IDs throughout - it fits for our application and its how AP should work.

It seems like even for some frameworks, depending on libraries for trickier bits is a better idea in the long run.

* the **client** module[1] wraps the signing of activities.
* the **auth** module[2] wraps the verification functionality.

Also for lower level use, there's the underlying module being wrapped by GoActivityPub: dadrus/httpsig [3]

[1] https://github.com/go-ap/client
[2] https://github.com/go-ap/auth
[3] https://github.com/dadrus/httpsig

I trust the direction, but I wouldn't count on a plug & play framework release within a plannable timeframe.

There have been other Python ActivityPub frameworks and libraries, from the top of my head I know https://git.fabiomanganiello.com/blacklight/pubby by @fabio and https://github.com/fedi-libs/apkit by @cocoa. See also https://delightful.coding.social/delightful-fediverse-development/ curated by @smallcircles.

there was a brief discussion about this in the fedify matrix channel a bit ago.

https://dev.funkwhale.audio/funkwhale/pyfed (though not sure how active development is for this)

https://codeberg.org/bovine/bovine/ (also looks dead)

and @julian@fietkau.social is building a library for SciOp (https://blog.sciop.net/2025-12-08/sfn-and-federation#federation-plans)

They can all be used to build Fediverse servers from building blocks.

I think other parts might be more piecemeal. I thing HTTP Signature libraries are awesome. https://github.com/social-web-foundation/activitystrea.ms is an AS2 library that I've used a lot, even though it's weird.

https://github.com/social-web-foundation/ap-components is a Web Components library for ActivityPub objects. Also kind of cool!

I think a lot of of building a Fediverse server -- or client! -- is implementing behaviour, which an engine like Fedify can do, but most libraries aren't going to do for you.
