Assuming you are on a Debian/Ubuntu based distro, make sure you have the following packages installed build-essential golang

However Gotify recomends using docker to build plugins
https://gotify.net/docs/plugin-deploy#with-docker-recommended

make GOTIFY_VERSION=“v2.0.5” FILE_SUFFIX=“for-gotify-v2.0.5” build

Use the gotify version according to the one installed on your system.
EX: make GOTIFY_VERSION="v2.4.0" FILE_SUFFIX="for-gotify-v2.4.0" build
for the latest release

the on build/you should have some .so files, copy the one for your machine arch to gotify plugins dir data/plugins

where a build for gotify v2.4.0 https://nowtransfer.de/3460c8e86670
copy only the one needed

You can get the rss of new releases with rss, and use rss plugin for Gotify

Debian can also be FreeBSD https://wiki.debian.org/Debian_GNU/kFreeBSD

Unfortunately died last year

Used duckdns for some years, but after some issues migrated to https://desec.io/

• https://desec.io
• https://nsupdate.info

For personal use https://forgejo.org/ or https://gogs.io/ should be enough

Start by choosing a network, try something like Libera Chat https://libera.chat/

You have some suggestions for IRC clients on their page, you can even use one on the browser. Browse the channels available, join, chat

Hosted or client, there’s IRC clients for everything, even on a Commodore 64 (https://csdb.dk/release/?id=197138)

I don’t use it for a longtime, but if it works why change it. It good for realtime chat, you can use it on a potato and some. Matrix chats also have IRC bridges so all can be on same chat.

Blink is a fork of WebKit wich is a fork of KHTML, KHTML exist since the '98, the codebase isn’t that younger too. Was tweaked by Apple then by Google, with some features that don’t exist on other engines.
