📄 Description

🚀 Feature: Automation Enhancements for Open WebUI

contributor license agreement

This PR adds three powerful automation features to Open WebUI, enabling advanced workflow orchestration, persistent memory, and intelligent tool routing.

✨ Features

1. N8N Pipeline Integration (PIPE v2.2.0)

Connect Open WebUI directly to N8N workflows for end-to-end automation.

Key Features:

  • ✅ SSE Streaming: Real-time Server-Sent Events for streaming workflow responses
  • ✅ Retry Logic: Exponential backoff with configurable retry policies
  • ✅ Execution Tracking: Full history of workflow runs with status, duration, errors
  • ✅ Analytics: Success rates, average duration, error tracking per configuration
  • ✅ User-Scoped: Complete user isolation and security

API Endpoints (9 total):

  • POST /api/n8n/config - Create N8N configuration
  • POST /api/n8n/trigger/{config_id} - Trigger workflow (non-streaming)
  • POST /api/n8n/trigger/{config_id}/stream - Trigger workflow (SSE streaming)
  • GET /api/n8n/configs - List user configurations
  • GET /api/n8n/analytics/{config_id} - Get workflow analytics
  • And 4 more...

2. Auto Memory Plugin

Automatically extract and store conversation facts using Named Entity Recognition.

Key Features:

  • ✅ NER (Spacy): Extracts people, organizations, dates, locations, products, etc.
  • ✅ ChromaDB Storage: Vector embeddings for semantic search
  • ✅ Deduplication: Prevents redundant memory storage
  • ✅ User-Scoped: Privacy-preserving user collections
  • ✅ Configurable: Confidence thresholds, entity types, context length

Use Cases:

  • Remember user preferences automatically
  • Track conversation context across sessions
  • Build persistent knowledge bases
  • Accumulate facts over time

3. AutoTool Filter

Automatically suggest relevant tools using semantic similarity matching.

Key Features:

  • ✅ Semantic Matching: Sentence embeddings + cosine similarity
  • ✅ Smart Suggestions: Top-K recommendations with confidence scores
  • ✅ Auto-Injection: Optional automatic tool selection
  • ✅ Embedding Cache: Fast similarity calculations (<500ms)
  • ✅ Configurable: Thresholds, model selection, caching options

Use Cases:

  • Reduce manual tool selection
  • Improve UX with smart tool discovery
  • Auto-route queries to appropriate tools
  • Suggest tools based on query semantics
