Epicyon is an AGPL licensed ActivityPub protocol compliant federated social network server suitable for hosting a small number of accounts on low power systems requiring minimal maintenance, such as single board computers. It's the ActivityPub equivalent of an email server, storing posts as human readable JSON on file, rather than in a database. It also uses only a small amount of RAM.
Epicyon is written in Python with a HTML+CSS web interface and uses almost no javascript which makes display in a web browser very lightweight.
Emojis, hashtags, photos, video and audio attachments, instance and account level blocking controls, moderation functions and reports are all supported. Build the community you want and avoid the stuff you don't. No ads. No blockchains or other Silicon Valley garbage.
Define the scope of your messages to reach the right people.
Epicyon supports many languages. Translations and emoji can easily be added. Alter the logo, backgrounds, terms of service and style to create a unique personality for your instance. Choose from a few different themes, or make a new one.
When creating a new post you can optionally also add a date, time and place. This will show up on the calendars of your followers, and makes organizing meetups or other community events simple. You can use message scopes to set up public events or private ones. To create reminders you can send yourself a DM with an event and it will appear on only your calendar.
Epicyon's lack of javascript makes it much more usable in shell based web browsers such as Lynx. As new web systems are deployed we should not be leaving anyone with minority use cases behind.
Some posts contain images and some don't. The media timeline enables you to view all your pet photos in one place.
Barter and gift physical items or services with other people on your instance. Search for shared items which you might want or post items you no longer have a use for. Promote ride shares or available accomodation without any unnecessary companies in the middle. Pool resources between trusted friends to build solidarity and have fun.
Define a set of skills in your profile and search for other people who have the skills you need. Organize teams who can get things done!
Want to remember a particular link or reply to something later? Bookmark your favorite posts and view them on the Saves timeline.
No algorithmic timelines. No rating or ranking of people. No trending stuff. Removing the artficial cruft of social networking allows you to focus on things you actually care about, instead of what someone else thinks you should pay attention to.
On a Debian based system:
sudo apt-get -y install tor python3-pip python3-socks imagemagick python3-numpy python3-setuptools python3-crypto python3-dateutil python3-pil.imagetk python3-idna certbot nginx
sudo pip3 install beautifulsoup4 pycryptodome
The following instructions install Epicyon to the /etc directory. It's not essential that it be installed there, and it could be in any other preferred directory.
Create a user for the server to run as:
sudo su
adduser --system --home=/opt/epicyon --group epicyon
Clone the repo:
cd /etc
git clone https://gitlab.com/bashrc2/epicyon
chown -R epicyon:epicyon /opt/epicyon
Create a daemon:
nano /etc/systemd/system/epicyon.service
Paste the following:

Activate the daemon:
systemctl enable epicyon
systemctl start epicyon
Create a web server configuration:

Enable the site:
ln -s /etc/nginx/sites-available/YOUR_DOMAIN /etc/nginx/sites-enabled/
Forward port 443 from your internet router to your server. If you have dynamic DNS make sure its configured. Add a TLS certificate:
certbot certonly -n --server https://acme-v01.api.letsencrypt.org/directory --standalone -d YOUR_DOMAIN --renew-by-default --agree-tos --email YOUR_EMAIL
Restart your web server:
systemctl restart nginx
If you are using the Caddy web server then see caddy.example.conf
Now you can navigate to your domain and register an account. The first account becomes the administrator.
