Bridges help users connect to external content (RSS, ActivityPub) but are not real Org Social accounts. They no longer appear in /feeds/, cannot be registered via POST, are skipped by both feed discovery tasks, and do not count in /stats/. A data migration removes bridge URLs already registered as feeds.
Org Social Relay
Introduction
Org Social Relay is a P2P system that acts as an intermediary between all Org Social files. It scans the network, creating an index of users, mentions, replies, groups and threads. This allows you to:

- Receive mentions and replies.
- Have a more comprehensive notification system.
- Read or participate in threads.
- Perform searches (tags and full text).
- Participate in groups.
- See who boosted your posts.
- Notify external sites linked from posts via Webmention (sending only; receiving them is not possible since plain text feeds cannot advertise an endpoint).
- Follow Mastodon/ActivityPub accounts and RSS/Atom feeds from any Org Social client through bridges (virtual social.org feeds).
Concepts
- Relay: A server running Org Social Relay (this software). Each relay maintains a local
relay-list.txtfile with URLs of other relays. Relays scan the network and share feed information with each other, creating a decentralized P2P network. - Client: An application that connects to a Relay to get information. It can be Org Social or any other application that implements the Org Social Relay API.
Installation
You need to have Docker and Docker Compose installed.
1. Create a .env file based on envExample
cp envExample .env
2. Edit variables as needed
nano .env
Important Environment Variables
GROUPS: Comma-separated list of group names available in the relay (optional)- Example:
GROUPS=Emacs,Org Social,Elisp - Group names can have spaces and capital letters
- Slugs (for URLs) are generated automatically (lowercase, spaces become hyphens)
- Leave empty if no groups are needed
- Groups allow users to participate in topic-based discussions
- Example:
3. Run with Docker Compose
docker compose up -d
Managing Relay Nodes
Local Relay List
This relay uses a local file (relay-list.txt in the project root) to manage the list of other relay nodes it connects to.
To add or remove relay nodes from your local instance:
# Edit the relay list file
nano relay-list.txt
# Add one relay URL per line, for example:
# https://relay.org-social.org
# https://other-relay.example.com
The relay will automatically discover feeds from these nodes every 3 hours.
Make your Org Social Relay public
If you want your Relay to be discoverable by other relay nodes, you can make a Pull Request to add your relay URL to the relay-list.txt file in this repository:
Steps to add your relay:
- Fork this repository
- Edit
relay-list.txtand add your relay URL on a new line:https://your-relay.example.com - Create a Pull Request with your changes
- Once merged, all relay nodes that update their code (via
git pull) will automatically discover your relay
This way, the network of relays grows organically as new nodes are added to the shared list.
Updating
To update your Org Social Relay to the latest version:
# Navigate to your installation directory
cd /path/to/org-social-relay
# Check if Docker containers are running
docker compose up -d --build
# Pull the latest changes
git pull
# Apply database migrations (if any)
docker compose exec django python manage.py migrate
# Restart the services
docker compose restart
Endpoints for clients
Important Note: URL Encoding
When passing URLs as query parameters (like feed or post), they must be URL-encoded to avoid conflicts with special characters like #, ?, &, etc.
Examples:
https://example.com/social.org→https%3A%2F%2Fexample.com%2Fsocial.orghttps://foo.org/social.org#2025-02-03T23:05:00+0100→https%3A%2F%2Ffoo.org%2Fsocial.org%232025-02-03T23%3A05%3A00%2B0100
You can use:
- Manual encoding:
curl "http://localhost:8080/endpoint/?param=encoded_url" - curl's automatic encoding:
curl -G "http://localhost:8080/endpoint/" --data-urlencode "param=unencoded_url"
HTTP Caching
All Relay endpoints that return data include HTTP caching headers:
ETag: A unique identifier for the current state of the relay (e.g.,"a1b2c3d4"). This value changes when the relay scans feeds for updates.Last-Modified: The timestamp when the relay last scanned feeds (e.g.,Wed, 01 Nov 2025 10:15:00 GMT).
All endpoints return the same ETag and Last-Modified values, which represent the global state of the relay. These headers are updated by the periodic feed scanning task.
Example:
curl -i http://localhost:8080/mentions/?feed=https://example.com/social.org
# Response headers include:
# ETag: "abc123"
# Last-Modified: Wed, 01 Nov 2025 10:15:00 GMT
CORS (Cross-Origin Resource Sharing)
All Relay endpoints have CORS enabled with Access-Control-Allow-Origin: *, allowing direct access from any frontend/web application. This means you can call the API directly from JavaScript in the browser without CORS restrictions.
Example:
// Fetch notifications directly from the browser
fetch('http://localhost:8080/notifications/?feed=https://example.com/social.org')
.then(response => response.json())
.then(data => console.log(data));

Each notification includes:
type: The notification type ("mention","reaction","reply", or"boost")post: The notification post URL (format:{author_feed}#{timestamp})emoji: (Only for reactions) The reaction emojiparent: (Only for reactions and replies) The post URL that received the notificationboosted: (Only for boosts) The original post URL that was boosted
Mentions only have type and post because you are the one being mentioned in someone else's post.
Reactions and replies have parent to indicate which of your posts received the reaction/reply.
Boosts have boosted to indicate which of your posts was shared.
To extract the author's feed from the post field, simply take the part before the # character. For example, from https://alice.org/social.org#2025-02-05T13:15:00+0100, the author is https://alice.org/social.org.
The by_type breakdown in meta allows you to show notification counts per type in your UI.
Optional parameters:
type: Filter by notification type (mention,reaction,reply,boost)- Example:
/notifications/?feed={feed}&type=reaction - Example:
/notifications/?feed={feed}&type=boost
- Example:
Real-time notifications (SSE)
/sse/notifications/ - Subscribe to real-time notifications via Server-Sent Events. The ?feed= parameter is optional:

The response includes:
reactions: Array of reaction objects withpost(URL) andemojireplies: Array of reply post URLs (excludes reactions - posts without mood)boosts: Array of boost post URLsparentChain: Array of parent post URLs from oldest to most recent (empty if post is root)
Note: This endpoint is optimized for displaying post details in a single request. It excludes nested replies (use /replies/?post={post_url} for the full thread tree) and only includes direct replies to maintain simplicity and performance.
The parentChain allows you to reconstruct the conversation context by showing all parent posts from the original root post up to the immediate parent. If the post is a reply to another post, you'll get the full chain; if it's a root post, the array will be empty.
Use cases:
- Display a post with all its interactions in one request
- Show conversation context with parent chain
- Optimize mobile/web apps by reducing HTTP requests
- Get post engagement metrics (reactions, replies, boosts count)
Get raw feed content
/feed-content/?feed={url feed} - Get the raw content of an Org Social feed file. This endpoint fetches and returns the original .org file content from the specified feed URL.
# URL must be encoded when passed as query parameter

"_links": {
"self": {"href": "/feed-content/?feed=https%3A%2F%2Fexample.com%2Fsocial.org", "method": "GET"}
}
}
The response includes:
content: The raw text content of the feed file (Org Mode format)
Use cases:
- Debug feed format issues
- Parse feeds locally in client applications
- Backup or archive feed content
- Analyze feed structure and properties
- Validate Org Social format compliance
Error handling:
- Returns 400 if the
feedparameter is missing or invalid - Returns 404 if the feed is not registered in the relay
- Returns 502 if the feed URL cannot be fetched (network error, server down, etc.)
Note:
- This endpoint fetches the feed content directly from the source URL in real-time and does not use cached data.
- The content is returned exactly as stored in the original
.orgfile, preserving all formatting, whitespace, and Org Mode properties.
Get replies/threads
/replies/?post={url post} - Get replies for a given post. This will return a tree structure with all the replies to posts in the given feed. If you want to see the entire tree, you must use the meta parent as a post.

Get statistics
/stats/ - Get aggregated statistics about the activity registered by the Relay. Data is grouped by year and month, plus a block of global counters. The month of each post is determined by its ID (RFC 3339 timestamp), not by when the Relay discovered it.

{

},
"_links": {

}
}
Counter definitions per month:
active_accounts: Number of distinct accounts that published at least one post (of any kind) during that month.total_posts: Every post registered that month, regardless of its type.posts: Original posts, meaning posts that are neither a reply (:REPLY_TO:) nor a boost (:INCLUDE:).replies: Posts with the:REPLY_TO:property that contain text content. Reactions are excluded.boosts: Posts with the:INCLUDE:property.reactions: Replies with a:MOOD:property and no text content.group_messages: Posts published in any group (:GROUP:property).polls: Polls created that month (posts with:POLL_END:). Poll closings are not counted.
Global counters:
registered_feeds: Total number of feeds currently registered in the Relay.total_accounts: Total number of accounts (profiles) known by the Relay.total_posts: Total number of posts registered, all time.total_follows: Total number of follow relationships between accounts.active_groups: Number of groups with at least one message.
Note: Counters are not mutually exclusive: a reply inside a group counts in both replies and group_messages, and a poll also counts in posts. Only posts, replies, reactions and boosts are disjoint between them, and together they add up to total_posts. Months with no activity are omitted. Like the rest of the endpoints, the response is cached and refreshed after each feed scan.
Bridges (follow ActivityPub accounts and RSS feeds)
Bridges expose external accounts as virtual social.org feeds served by the relay. Any Org Social client can follow them with a plain #+FOLLOW: line, no client changes needed.
Registration is implicit: the first request of an unknown account fetches it from the origin and stores it. Active bridges are refreshed every 15 minutes; bridges nobody has requested for 90 days are removed automatically (and re-created on the next request).
ActivityPub bridge
/bridge/activitypub/@{user}@{instance}/ - A Mastodon (or any ActivityPub) account as a virtual social.org feed (plain text).
curl http://localhost:8080/bridge/activitypub/@Mastodon@mastodon.social/

Following on from yesterday's blog post...
To follow the account, users add to their social.org:
#+FOLLOW: https://relay.org-social.org/bridge/activitypub/@Mastodon@mastodon.social/
Notes:
- Handles are case-insensitive; non-canonical spellings redirect (301) to the lowercase canonical URL.
- Only public top-level posts are bridged (no replies, no boosts), like Mastodon's public RSS.
- Content warnings become a
CW:first line; media attachments become Org links; hashtags become:TAGS:. - Instances running in authorized fetch mode (signed requests required) cannot be bridged.
/bridge/activitypub/ (without handle) lists the accounts already bridged by this relay.
RSS/Atom bridge
/bridge/rss/?url={feed_url} - An RSS or Atom feed as a virtual social.org feed (plain text). The url parameter must be URL-encoded.
curl -G http://localhost:8080/bridge/rss/ --data-urlencode "url=https://xkcd.com/rss.xml"
#+TITLE: xkcd.com
#+NICK: xkcd_com

To follow the feed:
#+FOLLOW: https://relay.org-social.org/bridge/rss/?url=https%3A%2F%2Fxkcd.com%2Frss.xml
Notes:
- Entry titles become
***sub-headings inside the post, followed by the converted content and a link to the original article. - Entries without a publication date are skipped; entries sharing the same date get IDs shifted forward one second so none is lost.
/bridge/rss/ (without url) lists the feeds already bridged by this relay.
Bridged feeds and the rest of the API
Bridged accounts are stored as regular profiles, so the existing endpoints (/profile/, /search/, /rss.xml?feed=..., ...) work with the bridge URL as the feed parameter. Bridged posts never trigger Webmentions nor notifications: the relay only mirrors external content.
Groups Configuration
Org Social Relay supports organizing posts into topic-based groups. Users can join groups to participate in focused discussions.
Configuring Groups
To configure groups in your relay, set the GROUPS environment variable with a comma-separated list of group names:
# In your .env file
GROUPS=Emacs,Org Social,Elisp,Programming,Tech
Groups Configuration Examples
No groups (default):
GROUPS=
# or simply omit the GROUPS variable
Single group:
GROUPS=Emacs
Multiple groups:
GROUPS=Emacs,Org Social,Elisp
Using Groups
Once configured, users can:
- View group-specific message threads
- Discover other group members
- Post messages to specific groups
The groups endpoints will only be available when groups are configured via the GROUPS environment variable.
RSS Feed
Org Social Relay provides an RSS feed of different types of content.
- The latest posts scanned from all registered feeds.
http://localhost:8080/rss.xml
- By tag.
curl http://localhost:8080/rss.xml?tag=emacs
- By author feed.
curl http://localhost:8080/rss.xml?feed=https%3A%2F%2Forg-social.org%2Fsocial.org
This RSS feed can be used in RSS readers to stay updated with new posts from the relay, but is limited to the latest 200 posts.
Technical information
The relay list is stored locally in relay-list.txt.
Crons
Scan feeds
Every minute, Relay will scan all registered feeds for new posts, mentions, replies, polls, and profile updates. After each scan, the cache is automatically cleared to ensure all endpoints return fresh data.
During the scan, users continue to see cached data (complete and consistent, even if slightly outdated). Once the scan completes and cache is cleared, the next request will fetch fresh data from the database.
Scan other nodes
Every 3 hours, Relay will search for new users on other nodes.
Discover new feeds
Every day at midnight, Relay analyzes the feeds of all registered users to discover new feeds they follow.
Cleanup stale feeds
Every 3 days at 2 AM, Relay automatically removes feeds that haven't been successfully fetched (HTTP 200) in the last 3 days. This keeps the relay efficient by removing inactive or dead feeds.
Refresh bridges
Every 15 minutes, Relay refetches the bridged ActivityPub accounts and RSS feeds that have been requested in the last 7 days. Dormant bridges are refreshed inline on their next request instead.
Cleanup stale bridges
Every 3 days at 3 AM, Relay removes bridged accounts that nobody has requested in the last 90 days, together with their stored profile and posts. They are re-created automatically if someone requests them again.
