Dify is a platform that allows users to easily create AI-powered tools without needing programming knowledge. Through a visual interface, users can build AI workflows by simply dragging and dropping, helping to improve business efficiency and automate tasks.

Here is the GitHub page for Dify.
To run Dify, you'll need Docker and Docker Compose.

sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
