Huginn — Self-Hosted Automation Agents That Monitor and Act on Your Behalf

Introduction

Huginn is a self-hosted system for creating agents that monitor the web, react to events, and perform automated actions. Think of it as a privacy-respecting, self-hosted alternative to IFTTT or Zapier where you own all the data and logic.

What Huginn Does

• Creates agents that watch web pages, RSS feeds, emails, and APIs for changes
• Chains agents together into complex automation workflows via event propagation
• Sends notifications via email, Slack, Pushbullet, or webhooks when triggers fire
• Scrapes websites on a schedule and extracts structured data
• Digests and summarizes collected information into periodic reports

Architecture Overview

Huginn is a Ruby on Rails application backed by MySQL or PostgreSQL. Agents run as background jobs via a delayed_job worker process. Each agent has a schedule, receives events from upstream agents, processes them, and optionally emits new events downstream. The web UI provides a visual graph of agent connections.

Self-Hosting & Configuration

• Deploy via Docker: docker run -d -p 3000:3000 ghcr.io/huginn/huginn
• Configure database connection via DATABASE_URL environment variable
• Set SMTP credentials for email-based agents and notifications
• Use HUGINN_SEED_USERNAME and HUGINN_SEED_PASSWORD for initial admin account
• Scale workers independently with docker run huginn /scripts/init bin/threaded.rb

Key Features

• Over 50 built-in agent types covering web scraping, APIs, email, and social media
• Visual directed graph editor showing event flow between agents
• Liquid templating for dynamic message formatting
• Scenario import and export for sharing automation recipes
• Dry-run mode for testing agents before enabling live execution

FAQ

Q: How is Huginn different from Zapier or IFTTT? A: Huginn runs entirely on your own server with no usage limits, no subscription fees, and no data shared with third parties.

Q: What programming knowledge is needed? A: Basic web concepts are enough for most agents. Complex scenarios may use Liquid templates or custom agent classes in Ruby.

Q: Can Huginn handle thousands of agents? A: Yes, though performance depends on server resources and job scheduling. Run multiple worker processes for heavy workloads.

Q: Is there a mobile app? A: No native app exists, but the web UI is responsive. Huginn can send push notifications to your phone via Pushbullet or ntfy.
