Keila is an open-souce Mailchimp alternative I’m developing and I aim to follow good coding practices with it. I’ve actually found myself referencing code from the project when explaining certain concepts to friends and I’ve occasionally even written tutorials on how certain parts of the code work.

I m the maintainer of GitHub - papercups-io/papercups: Open-source live customer chat · GitHub. We’re an open source live chat (intercom alternative). I think our quality needs some work tbh but a lot of our contributors come to us because we are very crud heavy so it tend to be a good starting point to check out Elixir code for your own projects.

We have over 1k real customers and users so if you want to see what an Elixir app looks like in production we are a good place to check out. Feel free to hop in our public Slack channel if you have any questions.

Or you can look at Bytepack .
It’s archived, but certainly a very good source of inspiration.

Or perhaps Changelog
