Dify.ai, a self-hosted prompt-management tool

[umnz]

From a quick scan it isn't very clear from the pricing page whether the self hosted community edition is feature complete or has certain features missing. Has anyone found a price/feature/comparison page? Otherwise I agree this looks very solid.

@umnz with the community self-hosted version, you can't modify their branding ("powered by dify" and logo) unless you obtain a license from them. If you just use dify as backend, you don't need to purchase license.

@taowang seems like a good candidate for Cloudron in that case!

"Importance of AI Prompt Management:

Consistency: Ensures consistent outputs across multiple interactions or users.
Efficiency: Saves time by reusing and refining effective prompts.
Performance optimization: Helps in fine-tuning prompts for better results.
Collaboration: Enables teams to share and improve prompts collectively.
Version control: Tracks changes and improvements in prompts over time.
Compliance: Helps maintain adherence to guidelines and ethical standards.

Issues in Prompt Management:

Versioning: Keeping track of different prompt versions and their effectiveness.
Organization: Managing a large number of prompts across various projects or use cases.
Sharing: Efficiently sharing prompts among team members or across departments.
Testing: Systematically testing and comparing different prompt variations.
Documentation: Maintaining clear records of prompt purposes, contexts, and performance.
Security: Ensuring sensitive prompts are not exposed to unauthorized users.
Scalability: Managing prompts as the number of AI applications and users grows.

How dify.ai can help:

Centralized repository: Provides a single location to store and organize all prompts.
Version control: Tracks changes to prompts over time, allowing for easy rollbacks if needed.
Collaboration features: Enables team members to work together on prompt development and refinement.
Testing and optimization: Offers tools to systematically test and compare different prompt versions.
Integration capabilities: Can potentially integrate with various AI models and platforms for seamless workflow.
User management: Allows for access control and permission settings for different team members.
Analytics: Provides insights into prompt performance and usage patterns.
Templating: Offers reusable prompt templates to maintain consistency across similar use cases.
API access: Likely provides API endpoints for programmatic access to prompts in applications.
Documentation: Facilitates adding context, notes, and performance data to each prompt.

This app is extremely complicated. It includes at least 9 services....

@zonzonzon er, you didn't vote

For folks who need to self host this app, I created a comprehensive tutorial.

Create a fresh server, update and upgrade the system, install docker and docker compose with this one command.

sudo apt-get update -y &&
sudo apt-get upgrade -y &&
sudo apt-get install -y apt-transport-https ca-certificates curl software-properties-common gnupg lsb-release &&
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg &&
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null &&
sudo apt-get update -y &&
sudo apt-get install -y docker-ce &&
sudo usermod -aG docker $USER &&
sudo curl -L https://github.com/docker/compose/releases/download/v2.26.1/docker-compose-`uname -s-uname -m` -o /usr/local/bin/docker-compose &&
sudo chmod +x /usr/local/bin/docker-compose && \

Clone the Repo

git clone https://github.com/langgenius/dify.git

Customize the .env file

cd dify/docker
cp .env.example .env

I only customized the following variables.
APP_WEB_URL=your_domain_name
NGINX_HTTPS_ENABLED=true
NGINX_SSL_CERT_FILENAME=cert.pem
NGINX_SSL_CERT_KEY_FILENAME=key.pem

Ctrl S to save, Ctrl X to exit the nano editor.
cd -

Create SSL Certificate

Create ssl certificate at Cloudflare (open SSL/TSL tab and open Original Server)

nano dify/docker/nginx/ssl/cert.pem
Copy and paste the Cloudflare certificate, then Ctrl S, Ctrl X

nano dify/docker/nginx/ssl/key.pem
Copy and paste the Cloudflare SSL key, then Ctrl S, Ctrl X

Deploy

cd dify/docker
docker compose up -d

Upgrade

cd dify/docker
docker compose down
git pull origin main
docker compose pull
docker compose up -d

Setting Up Automated Backups for Dify Using Restic and Cloudflare R2

Step 1: Install Restic

1. Connect to your server via SSH.
2. Update your package list and install Restic:

   sudo apt update
   sudo apt install restic
   

Step 2: Prepare Your Cloudflare R2 Bucket

1. Create a new R2 bucket in your Cloudflare account if you haven't already.
2. Note down the following information from your Cloudflare R2 setup:
   • Bucket name
   • Access Key ID
   • Secret Access Key
   • R2 Endpoint URL

Step 3: Create the Backup Script

1. Create a new directory for the Restic script:

   mkdir -p /root/restic
   

2. Create and open the backup script using nano:

   nano /root/restic/backup.sh
   

3. Copy and paste the following content into the file:

   #!/bin/bash
   
   # Set environment variables for Restic
   export RESTIC_REPOSITORY="s3:YOUR_R2_ENDPOINT_URL/YOUR_BUCKET_NAME"
   export AWS_ACCESS_KEY_ID="YOUR_ACCESS_KEY_ID"
   export AWS_SECRET_ACCESS_KEY="YOUR_SECRET_ACCESS_KEY"
   
   # Set the backup source
   BACKUP_SOURCE="/root/dify/docker/volumes"
   
   # Perform the backup
   restic backup $BACKUP_SOURCE
   
   # Prune old snapshots (keep last 7 daily, last 4 weekly, and last 12 monthly backups)
   restic forget --keep-daily 7 --keep-weekly 4 --keep-monthly 12 --prune
   
   # Check the repository for errors
   restic check
   

4. Replace the following placeholders with your actual Cloudflare R2 information:

   • YOUR_R2_ENDPOINT_URL: Your Cloudflare R2 endpoint URL
   • YOUR_BUCKET_NAME: Your R2 bucket name
   • YOUR_ACCESS_KEY_ID: Your R2 Access Key ID
   • YOUR_SECRET_ACCESS_KEY: Your R2 Secret Access Key

5. Save the file and exit nano:

   • Press Ctrl + X
   • When prompted to save, press Y
   • Press Enter to confirm the file name

6. Make the script executable:

   chmod +x /root/restic/backup.sh
   

7. Secure the script (as it contains sensitive information):

   chmod 700 /root/restic/backup.sh
   

Step 4: Initialize the Restic Repository

1. Set the environment variables (replace with your actual R2 information):

   export RESTIC_REPOSITORY="s3:YOUR_R2_ENDPOINT_URL/YOUR_BUCKET_NAME"
   export AWS_ACCESS_KEY_ID="YOUR_ACCESS_KEY_ID"
   export AWS_SECRET_ACCESS_KEY="YOUR_SECRET_ACCESS_KEY"
   

2. Initialize the Restic repository:

   restic init
   

Step 5: Set Up Daily Backups

1. Open the crontab file:

   crontab -e
   

2. If prompted to select an editor, choose nano by entering the corresponding number.

3. Add the following line at the end of the file to run the backup daily at 3 AM:

   0 3 * * * /root/restic/backup.sh > /root/restic/backup.log 2>&1
   

4. Save the file and exit nano:

   • Press Ctrl + X
   • When prompted to save, press Y
   • Press Enter to confirm

Verifying the Setup

To ensure everything is set up correctly:

1. Run the backup script manually:

   /root/restic/backup.sh
   

2. Check the Restic repository for snapshots:

   restic snapshots
   

Restoring from a Backup

To restore your data:

1. List available snapshots:

   restic snapshots
   

2. Restore the latest snapshot:

   restic restore latest --target /path/to/restore
   

   Replace /path/to/restore with the directory where you want to restore the data.

Done.
