📂 Repository Organization

Workflow Collection

2,053 workflows with meaningful, searchable names
365 unique integrations across popular platforms
29,445 total nodes with professional categorization
Quality assurance - All workflows analyzed and categorized

Advanced Naming System ✨

Our intelligent naming system converts technical filenames into readable titles:

Before: 2051_Telegram_Webhook_Automation_Webhook.json
After: Telegram Webhook Automation
100% meaningful names with smart capitalization
Automatic integration detection from node analysis

Use Case Category ✨

The search interface includes a dropdown filter that lets you browse 2,000+ workflows by category.

The system includes an automated categorization feature that organizes workflows by service categories to make them easier to discover and filter.

How Categorization Works

Run the categorization script
```
python create_categories.py
```
Service Name Recognition The script analyzes each workflow JSON filename to identify recognized service names (e.g., "Twilio", "Slack", "Gmail", etc.)
Category Mapping Each recognized service name is matched to its corresponding category using the definitions in context/def_categories.json. For example:
- Twilio → Communication & Messaging
- Gmail → Communication & Messaging
- Airtable → Data Processing & Analysis
- Salesforce → CRM & Sales
Search Categories Generation The script produces a search_categories.json file that contains the categorized workflow data
Filter Interface Users can then filter workflows by category in the search interface, making it easier to find workflows for specific use cases

Available Categories

The categorization system includes the following main categories:

AI Agent Development
Business Process Automation
Cloud Storage & File Management
Communication & Messaging
Creative Content & Video Automation
Creative Design Automation
CRM & Sales
Data Processing & Analysis
E-commerce & Retail
Financial & Accounting
Marketing & Advertising Automation
Project Management
Social Media Management
Technical Infrastructure & DevOps
Web Scraping & Data Extraction

Contribute Categories

You can help expand the categorization by adding more service-to-category mappings (e.g., Twilio → Communication & Messaging) in context/defs_categories.json.

Many workflow JSON files are conveniently named with the service name, often separated by underscores (_).
