README

A self-hosted ActivityPub server implementation for Laravel 13, enabling federation with the Fediverse (Mastodon, Pleroma, Misskey, Pixelfed, PeerTube, etc.).

Features

WebFinger — Actor discovery via /.well-known/webfinger
Actor profiles — ActivityStreams JSON-LD representations
Inbox/Outbox — OrderedCollection with pagination support
HTTP Signatures — RSA-SHA256 signing and verification with Digest support
Federation — Outbound delivery of Create, Update, Delete, Follow, Accept, Like, Announce, Undo, and replies
Follower management — Track followers from remote servers
Shared inbox — POST /inbox for instance-level activity delivery
NodeInfo — /.well-known/nodeinfo and /nodeinfo/2.0
host-meta — /.well-known/host-meta with WebFinger XRD template
Blade-based Fediverse web UI — Dashboard, timeline, inbox, discover, profile editing
Artisan commands — activitypub:create-actor, activitypub:prune-activities
Queue jobs — Async delivery with retries, remote actor fetching with deduplication

Installation

composer require danielpetrica/laravel-activitypub

Publish the configuration and migrations:

php artisan vendor:publish --tag=activitypub-config
php artisan vendor:publish --tag=activitypub-migrations
php artisan migrate

Configuration

ACTIVITYPUB_DOMAIN=https://your-domain.com
ACTIVITYPUB_FEDERATION_ENABLED=true   # enable outbound federation
ACTIVITYPUB_FEDIVERSE_ENABLED=true    # enable Blade-based web UI

Creating an Actor

php artisan activitypub:create-actor --username=yourname --name="Your Name"

Federating Content

Have your Eloquent model implement FederatableContentContract and use the FederatesContent trait:

use DanielPetrica\LaravelActivityPub\Contracts\FederatableContentContract;
use DanielPetrica\LaravelActivityPub\Traits\FederatesContent;

class Post extends Model implements FederatableContentContract
{
    use FederatesContent;

    public function shouldFederate(): bool { return $this->status === 'published'; }
    public function activityPubActor(): ActorContract { /* return your actor */ }
    public function getActivityPubId(): string { return url("/posts/{$this->id}"); }
    // ... implement remaining contract methods
}

Testing

vendor/bin/pest --filter=InboxProcessingTest
vendor/bin/pest --filter=ConsoleCommandsTest

Postponed Features (TODO)

These items are planned for future releases:

Move / AlsoKnownAs — Account migration support (see ActivityPub spec §5.4)
Block activity — Blocking remote actors, filtering blocked content from timeline
Tailwind CSS build step — The Fediverse web UI currently loads Tailwind via CDN. Replace with a compiled CSS build step for production.
Full OrderedCollectionPage pagination — Currently returns OrderedCollection with first/last pointers. Proper page-by-page OrderedCollectionPage responses should be added.
JSON-LD compaction — Handle compacted JSON-LD payloads from Pleroma/Akkoma.
outbox_url shared inbox — Add sharedInbox to actor profiles for servers that support it.
Admin dashboard — Filament-based admin panel for managing actors, viewing federation stats.
