For web applications, Phoenix is very popular: https://github.com/phoenixframework/phoenix; https://github.com/phoenixframework/phoenix; it uses some OTP directly and its dependencies like the web-server Cowboy use it as well. DB development usually uses Ecto: https://github.com/elixir-ecto/ecto https://github.com/elixir-ecto/ecto, it has OTP servers for connection pooling and other tasks. For managing background tasks I use Honeydew: https://github.com/koudelka/honeydew https://github.com/koudelka/honeydew
