Build Status

📕 yarn is a Self-Hosted, Twitter™-like Decentralised micro-Blogging platform. No ads, no tracking, your content, your data!

  • yarnd is the Yarn.social pod backend server
  • yarnc is the command-line client to yarnd API and command-line Twtxt client

See Yarn.social for more deatils


Pre-built Binaries

As a first point, please try to use one of the pre-built binaries that are available on the Releases page.

Using Homebrew

We provide Homebrew formulae for macOS users for both the command-line client (yarn) as well as the server (yarnd).

brew tap yarnsocial/yarn https://git.mills.io/yarnsocial/homebrew-yarn.git
brew install yarn

Run the server:


Run the command-line client:


Building from source

This is an option if you are familiar with Go development.

  1. Clone this repository (this is important)
git clone https://git.mills.io/yarnsocial/yarn.git
  1. Install required dependencies (this is important)

Linux, macOS:

make deps

Note that in order to get the media upload functions to work, you need to install ffmpeg and its associated -dev packages. Consult your distribution's package repository for availability and names.


  • Install gmake
  • Install pkgconf that brings pkg-config gmake deps
  1. Build the binaries

Linux, macOS:





Command-line Client

  1. Login to your Yarn.social pod:
$ ./yarn login
INFO[0000] Using config file: /Users/prologic/.twt.yaml
  1. Viewing your timeline
$ ./yarn timeline
INFO[0000] Using config file: /Users/prologic/.twt.yaml

Hey @rosaelefanten 👋 Nice to see you have a Twtxt feed! Saw your [Tweet](https://twitter.com/koehr_in/status/1326914925348982784?s=20) (_or at least I assume it was yours?_). Never heard of `aria2c` till now! 🤣 TIL

  1. Making a Twt (post):
$ ./yarn post
INFO[0000] Using config file: /Users/prologic/.twt.yaml
Testing `yarn` the command-line client
INFO[0015] posting twt...
INFO[0016] post successful

For additional help on using the yarnc command-line client:

$ yarnc help
This is the command-line client for Yarn.social pods running
yarnd. This tool allows a user to interact with a pod to view their timeline,
following feeds, make posts and managing their account.

  yarnc [command]

Available Commands:
  completion  generate the autocompletion script for the specified shell
  help        Help about any command
  login       Login and euthenticate to a Yarn.social pod
  post        Post a new twt to a Yarn.social pod
  stats       Parses and performs statistical analytis on a Twtxt feed given a URL or local file
  timeline    Display your timeline

  -c, --config string   set a custom config file (default "/Users/prologic/.yarnc.yml")
  -d, --debug           Enable debug logging
  -h, --help            help for yarnc
  -t, --token string    yarnd API token to use to authenticate to endpoints (default "$YARNC_TOKEN")
  -u, --uri string      yarnd API endpoint URI to connect to (default "http://localhost:8000/api/v1/")

Use "yarnc [command] --help" for more information about a command.

Deploy with Docker Compose

Run the compose configuration:

docker-compose up -d

Then visit: http://localhost:8000/

Web App

Run yarnd:

yarnd -R

NOTE: Registrations are disabled by default so hence the -R flag above.

Then visit: http://localhost:8000/

You can configure other options by specifying them on the command-line or via environment variables.

To view the available options simply run:

$ ./yarnd --help

Valid environment value names are the long-option version of a flag in all uppercase with dashes repalced by an underscore _.

Configuring your Pod

At a bare minimum you should set the following options:

  • -d /path/to/data
  • -s bitcask:///path/to/data/twtxt.db (we will likely simplify/default this)
  • -n <name> to give your pod a unique name.
  • -u <url> the base url (public facing) of how your pod will be reahced on the web.
  • -R to enable open registrations.
  • -O to enable open profiles.

Most other configuration values should be done via environment variables.

It is recommended you pick an account you want to use to "administer" the pod with and set the following environment values:

  • ADMIN_USER=username
  • ADMIN_EMAIL=email

In order to configure email settings for password recovery and the /support and /abuse endpoints, you should set appropriate SMTP_ values.

It is highly recommended you also set the following values to secure your Pod:


These values should be generated with a secure random number generator and be of length 64 characters long. You can use the following shell snippet to generate secrets for your pod for the above values:

$ cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 64 | head -n 1

There is a shell script in ./tools/gen-secrets.sh you can use to conveniently generate the required secrets for a production pod. The output is designed to by copy/pasted into a docker-compose.yml file with the right indentation.

DO NOT publish or share these values. BE SURE to only set them as env vars.

NOTE: The Dockerfile specifies that the container run as the user yarnd with uid=1000. Be sure that any volume(s) you mount into your container and use as the data storage (-d/--data) path and database storage path (-s/--store) is correctly configured to have the correct user/group ownership. e.g: chorn -R 1000:1000 /data

Production Deployments

Docker Swarm

You can deploy yarnd to a Docker Swarm cluster by utilising the provided yarn.yaml Docker Stack. This also depends on and uses the Traefik ingress load balancer so you must also have that configured and running in your cluster appropriately.

docker stack deploy -c yarn.yml
