Python
Discord API
Docker
Darwin is a proprietary bot framework primarily designed for Discord. It is designed for strict command processing and to be easily extendable with new commands.
It was originally designed over Discord REST API directly, but later it was extended to use the discord.py library.
Currently, framework uses pycord library. It also offers a web interface for SSO, content management, and user management.
Framework is still in use by multiple communities and is actively maintained.
